1. What is qBittorrent, and What Makes it Stand Out?

qBittorrent is a cross-platform and open-source torrent client. It is supported by major operating systems, including Linux, macOS, Windows, FreeBSD, and OS/2. The qBitorrent application is written in C++ and based on the Qt 5 toolkit and the libtorrent-rasterbar library. It is available in 70 different languages.

qBittorrent is designed to serve as an excellent open-source (and free) alternative to uTorrent, BitTorrent, and other commercial BitTorrent clients in the market. The software is known to be reasonably reliable, stable, and fast.

qBittorrent is developed by a strong community of volunteers. To learn more about the project contributors and repository, visit GitHub qBittorrent project.

a. qBittorrent Compatibility and Applications

You can use qBittorrent with macOS, Windows, Linux, FreeBSD, and OS/2. The latest stable version is qBittorrent v4.4.2

  • Windows: qBittorrent is supported by Windows 7, 8, 10, and 11. You can download 32-bit & 64-bit qBittorrent installers or PGP signature (FossHub).
  • macOS: qBittorrent is supported by macOS Catalina, Big Sur, and Monterey. You can download qBittorrent macOS from DMG or PGP signature (FossHub).
  • Linux. qBittorrent latest version (qBittorrent v4.4.2) works for Ubuntu 20.04 (or other similar distros such as Debian). You can download qBittorrent Linux from AppImage or PGP signature (FossHub). The AppImage is created directly on Ubuntu 20.04 and uses the latest version for Qt6, libtorrent, boost, and OpenSSL.

You can also download qBittorrent from source tarball or binaries. All source tarballs and binaries are PGP signed (public key for PGP signing) starting from qBittorrent v3.3.4. You can download qBittorrent source tarball from TAR.GZ and PGP signature (SourceForge)

Other remarkable qBittorrent apps are worth mentioning.

Being open-source, you can use several new projects to improve your qBittorrent experience and torrent control. For example:

  • qBittorrent Remote Free. A mobile qBittorrent Android remote control client that lets you control qBittorrent through the WebUI API. You can add torrents, pause, resume, delete, copy magnet links, rename, etc.
  • qBittorrent Home Assistant. Home Assistant is an open-source home automation software that can run on a Raspberry Pi or a local server. It integrates with more than a thousand devices and services, including qBittorrent. With the Home Assistant, you can monitor your qBittorrent downloads and set up torrent automation.
  • The qBittorrent Controller for Android is an open-source mobile qBittorrent Android app to manage your qBittorrent (web UI) servers. With this app, you’ll be able to add torrents, pause, start, erase, and more.

b. qBittorrent Features.

The qBittorrent is not just another torrent client. Unfortunately, qBittorrent is underrated, but it has several features that make it stand out as one of the best.

  • qBittorrent is lightweight. The qBittorrent is very compact. For instance, the Windows 10 64-bit installer is 28.8 MBs, the macOS installer is 32.5, and the Linux AppImage installer is 38.6MBs.
  • Web User Interface. qBittorrent’s UI is visually appealing and minimalistic. The newest version, qBittorrent v4.2.2, allows you to use unofficial Qt UI themes for all operating systems. The UI comes without any ads or other unnecessary bloatware.
  • Integrated torrent search engine. qBittorrent’s integrated torrent search engine allows you to search simultaneously in different torrent search sites and categories.
  • RSS feed support. qBittorrent comes with support for RSS so that you can download torrents automatically. It also includes advanced download filters (incl. regex) to enhance your RSS feeds.
  • Supports different P2P protocols. qBittorrent supports Distributed hash table (DHT), peer exchange protocol (PEX), and local peer discovery (LSD) protocols.
  • Encrypted connections. qBittorrent comes with built-in encryption to allow (or force) your client to connect to encryption-enabled peers. Enforcing qBittorrent encryption may reduce the number of available peers but is a good start for encryption.
  • Remote torrent management. Control (start, pause, queue) your torrents remotely through a secured web user interface similar to the original UI (written in AJAX). With this feature, you can manage your home-based torrent client anywhere from the web UI.
  • Torrent creation tool. qBittorrent comes with a complete built-in torrent creation tool. It lets you create V1, V2, or hybrid torrents; you can set it as a private torrent and start torrenting it immediately.
  • Advanced torrent control. Control your torrents through queueing and prioritizing. You can also select the torrent content to be downloaded and prioritize it. In addition, you can control trackers and peers.
  • Bandwidth scheduler. A feature that allows you to limit the bandwidth for your downloads and uploads to ensure that you keep torrenting without affecting the entire Internet connection.
  • Port forwarding support. qBittorrent supports port forwarding through Universal Plug and Play (UPnP) and NAT Port Mapping Protocol (NAT-PMP).

Sure, the default settings work… *if you love slow downloads.* Fix that now 🎯

2. The Best qBittorrent Settings for Speed.

qBittorrent comes optimized for speed. First, because it is free from ads, Malware, or any bloatware that hurts performance and speed, and second, because it is by default ready to download and upload torrents without modifying qBittorrent settings. But still, no bandwidth and computer are the same. So by tweaking a few qBitorrents settings for speed, you’ll get even faster torrent downloads and uploads.

In this section, we’ll go through the qBittorrent best settings for speed.

a. Let’s optimize speed outside qBittorrent.

  • The health of your torrent determines the speed. If you are getting slow speeds on qBittorrent, then it is likely that your torrent file is unhealthy (low on seeders). One of the best pieces of advice to improve qBittorrent is to get a healthy torrent with a good amount of seeders.
  • Your bandwidth determines torrent speed. Speed is relative to requirements and available resources. For some people, 1-5MB is fast; for others, 50-100 is fast, and so on. If you want faster downloads, you might have to change or config your Wifi AP, reduce the number of connected clients, and call your ISP to expand that bandwidth.
  • Your computer and bandwidth-hungry apps. Another reason why you are getting slow speeds is when your computer (memory and CPU) is unable to process the amount of data coming in, or there are other bandwidth-hungry apps open such as video streaming, automatic backups, and video calls, etc., eating up your bandwidth.

b. Help qBittorrent find quality peers and seeds.

A healthy torrent swarm has a good share ratio between seeders (users with the entire file) and peers (the users getting the content and helping distribute it. A third player comes into place, leechers the users downloading the content but not uploading it. If the share ratio within a torrent swarm is unbalanced, for instance, there are more leechers than peers, and everyone in the swarm will experience slow speeds.

There are (tracker-less) methods such as DHT and PEX can help you find more peers and seeds to download your content. After you finish downloading the content, keep it sharing for some time.

To enable DHT and PEX:

  • Go to qBittorrent settings > BitTorrent > Privacy.
  • Make sure that DHT and PEX. Enable “Local Peer Discovery” only if you are on a large (or campus) LAN.
  • Ensure “Encryption mode” is set to “Allow Encryption.” Although this encryption is no substitute for a VPN, it does help hide traffic from ISPs (more on this in the next section). Allow encryption allows you to download/upload from/to everyone, but if both clients have “Allow Encryption,” the traffic will be encrypted. Don’t use “Require Encryption,” as this option will limit you to only users with the “Require Encryption” flag.

Good sharing ratios are vital for maintaining membership in private trackers. If you are enrolled in a private tracker, DHT and PEX are irrelevant (they are trackless methods). Private trackers set the “private” flag on their torrents, so they won’t be distributed to other peers outside the private tracker. An excellent way to increase a torrent’s share ratio is using a seedbox.

c. Config upload and download to unlimited.

  • Click on qBittorrent settings > Speed.
  • Make sure that Global Rate Limits are set to infinite > ∞
  • The ∞ setting is set by default, which means that qBittorrent is not setting any caps on the speed. If there is a different value, then it is likely that someone tweaked it.
  • Do not limit upload speed. The BitTorrent protocol was designed for sharing. It uses a choking mechanism that affects download speed when upload speed is compromised.

You can also enable rate limits and configure them to take effect on a specified schedule. For example, this option can be helpful when traffic in your network is in higher demand during the daytime. To set this config right, follow these settings:

  • Set an upload and download rate.
  • Enable “schedule the use of alternative rate limits.
qBittorrent speed

  • The alternative rate limits will automatically be enabled according to the schedule.
  • You can also switch between global and alternate speed limits manually from the speedometer icon on the bottom bar.

d. Select the right port to improve speed.

qBittorrent uses a TCP port to establish communications with peers and trackers (except DHT, which uses various UDP ports to communicate with peers). Within local networks, firewalls and NATs do not simply trust any outsider (peer) from accessing the local network through the requesting port.

Software such as qBittorrent and various routers now support protocols like UPnP and NAT-PMP to discover local network services (open the best port). Although UPnP is generally safe, it can ease insecure connections. If you are ok using UPnP, your router supports it, and you don’t want to manually forward a specific port, follow the following best qBittorrent settings for speed and connectivity.

What if the only thing slowing you down… is one wrong port? Learn more about the fix 🔓

e. How to speed up qBittorrent

  • Go to qBittorrent settings > Connection.
  • Check the box “Use UPnP / NAT-PMP port forwarding from my router.”
  • Click on “Random” to get a new port number. Or use ports within the 49160-65534 range. Changing a port can improve your qBittorrent speed, as ISPs are commonly known to block common BitTorrent ports. Port forwarding will help bypass port ranges blocked by your ISP.
qBittorrent ports

  • You can use online services such as CanYouSeeMe or ​​Portchecker to verify if your application is reachable from the outside through your NAT, router, and firewall. The service will detect your IP address, but you need to enter your port number.
  • While testing for open ports, leave the qBitttoren application online. If your port is open, go ahead and test your speed.
  • But if it’s closed, you’ll need to port forward the port manually. For instance, port 22512 (which was randomly obtained) is closed in my case.
qBittorrent port checker
08 – Photo by Portchecker

It is important to note that even though an online port checker sees my port as closed, there are still many peers within a torrent swarm that will be able to connect to my qBittorrent client.

  • This is because qBittorrent is running in passive mode, which means my client can’t accept incoming connections but can connect to peers that accept connections.
  • If active mode is enabled, if my port were open (which we will do by port forwarding), then my qBittorrent client would be able to accept incoming connections.

f. Manual qBittorrent port forwarding.

Port forwarding is essential for enabling remote access for peers to your content on the local network. Use port forwarding if your router/NAT/firewall does not support UPnP, you don’t trust UPnP, or if you are downloading from small torrent swarms. Port forwarding will allow your router/NAT/firewall to accept incoming connections and connect to peers that are accepting incoming connections; more peers = more speeds.

To manually port forward, you’ll need to access your router and configure a new entry so that the external world can access your qBittorrent application and its contents. Logging to your router/firewall and port forwarding are beyond the scope of this guide.

3. Best qBittorrent Settings for Anonymous Downloads.

The previous section dealt with the best qBittorrent settings for speed. But still, aside from getting good speed rates, torrent users usually also want to improve their anonymity. There are a couple of qBittorrent settings and tools outside the client that can help you protect your privacy.

a. Built-in Encryption.

In the previous section, we enabled qBittorrent’s built-in encryption. Although this encryption is not a substitute for a VPN, enabling it does help build the first layer of defense. To do this:

  • Go to qBittorrent settings > BitTorrent > Privacy.
  • Ensure “Encryption mode” is set to “Allow Encryption.”
qBittorrent encryption

  • qBittorrent also comes with Anonymous Mode. This mode stops the client from broadcasting the client’s information (i.e user-agent) used for fingerprinting. When Anonymous mode is enabled, qBittorrent will attempt to mask its identity.
  • Use anonymous mode for public trackers, NOT for private trackers.

NOTE for Private Tracker users:Bear in mind that if you are downloading torrents from a private tracker, the Anonymous mode will remove the entire information from the torrent tracker. Private trackers use passkeys to identify themselves, so if this is removed, you will not be recognized as a valid user. You will not be able to connect to the tracker and the torrent swarm.

  • To enable it go to qBittorrent settings > BitTorrent > Privacy > Check on “Enable Anonymous Mode”. Click on “Apply” > “Ok”.
  • It is recommended to enable Anonymous mode if you are using a proxy or VPN.

b. Configuring a proxy in qBittorrent.

Proxies are exceptional for improving the privacy of torrents. Although they do not encrypt traffic (as VPNs do), they help by masking your IP in torrent swarms. Of course, proxies were not designed for the same purpose as VPNs (VPNs vs. proxies), so they can be suitable for different use cases. For instance, proxies do not encrypt traffic, making them faster than VPNs for torrenting.

  • To enable a proxy server on qBittorrent, go to Preferences > Connection > Proxy Server.
  • Select the type of proxy, for instance, SOCKS5 or HTTP.
  • Enter the proxy server’s IP and port.
  • If you choose SOCKS5, you may need to enter your username and password. Authentication is an advantage of SOCKS5 when it comes to security.
  • Click on “Use proxy for peer connections” or “Use proxy only for torrents.”

c. qBittorrent VPN.

You should use Virtual Private Networks (VPNs) when torrenting from unsecured public trackers. VPNs also mask your IP, so if you torrent from a public tracker, the torrent swarm will see the VPN’s server IP and not yours. In addition, VPNs build an encrypted tunnel between the VPN client and the VPN server, bypassing any traffic throttling or monitoring from intermediaries like ISPs, governments, or hackers.

NOTE for private tracker users: Bear in mind that most private trackers do not allow VPNs because there is no reason to hide your IP within the private swarm. Always check whether the private tracker you are using allows VPNs; if so, then proceed.

Tips about choosing a VPN for torrenting:

  • Ensure the VPN server provider supports P2P or torrenting.
  • If you are using a private tracker, you do not necessarily need a VPN unless you are concerned about the middlemen (ISPs, governments, etc.).
  • If you are torrenting from a public tracker, always use a VPN.
  • Choose VPNs with a no-logs policy and large distributed networks.
  • The OpenVPN service is the most popular VPN technology that uses SSL/TLS for key exchange. It has become the de facto standard in the open-source networking space.

d. Seedbox.

Seedboxes are cloud-based Virtual Private Servers (VPS) built explicitly for torrenting. Seedboxes like Rapidseedbox come with pre-installed torrenting applications, including qBittorrent, BitTorrent, uTorrent, and other applications like Plex, VPN, Jackett, and Brave, to make the torrenting even better. Rapidseedbox offers shared or dedicated seedboxes with speeds ranging from 1GBps to 10GBps.

With a seedbox, you download and upload torrents from and to the VPS seedbox and only use your local computer for remote login and torrent management. Torrents and their content are stored in the cloud, and when you want to download them to your premises, you can use other secure methods like RSync or SFTP. In addition, you can also use a seedbox with a Plex media server to organize and stream all your content online.

When you use qBittorrent with a Seedbox, you’ll get the following benefits:

  • Download at high speeds up to 10Gbps
  • Unlimited traffic (based on a fair use policy).
  • Storage from 1TB to 5.6TBs.
  • Dedicated IP
  • SSH access.
  • Remote Desktop
  • Built-in Plex media server with 4k streaming capabilities.

4. User Experience with qBittorrent Settings.

Some qBittorrent settings such as UI customization, search engine, and RSS downloads can help you improve the user experience with qBittorrent.

a. qBittorrent User Interface.

qBittorrent comes with a uTorrent-like secure web User Interface (UI). You can remotely control the software through the secure UI. As of the newest qBitTorrent v4.22, you can use custom unofficial Qt UI themes on all operating systems.

  • By default (as of the macOS qBittorrent v4.4.2), the web UI comes with the qBittorrent dark theme, which looks fantastic to the eye. One particular feature is its clean and free-of-ads UI.
qBittorrent UI

You can also use customized unofficial Qt UI themes for all platforms. For instance, you can download a different version of the qBittorrent dark theme from its official repository [qBittorrentDarktheme] and install it.

b. qBittorrent UI Navigation.

The left-hand menu divides the web UI, containing vital torrent status information on categories, tags, and trackers. The top bar menu provides necessary torrenting actions such as “Add a torrent link” (or magnet links), add a torrent file, delete, resume, pause, and preferences. The bottom bar shows you information on the particular torrent. You can get information on torrent health, including progress, availability, trackers, peers, HTTP sources, content, and speed.

c. Searching through the UI.

One of the cool features of qBittorrent is that it comes with an integrated torrent search engine (written in Python). The search engine allows you to search for torrents on simultaneous torrent search sites and specify your search request based on category, for instance, music, movies, books, software, etc.

To access your qBittorrent search engine:

  • Go to View > Search Engine
qBittorrent search engine

  • To enable the qBittorrent search engine, you’ll have to install the qBittorrent search plugin. Go ahead and click on “Search plugins … ” > “Check for updates.”
  • Once you click on “Check for updates,” you’ll get a list of search plugins— usually popular public torrent site indexes. If you are searching and downloading torrents through a public torrent tracker, it’s best to use a VPN.
  • Click on “Install a new one” if a particular search plugin is not on the list. You can add a search plugin via the local link or web URL.

d. qBittorrent RSS Feeds.

qBittorrent supports RSS feeds so that you can automatically download your favorite torrents. Whenever a new torrent is added and listed on an RSS feed, you can configure your client to download it automatically. This support includes advanced download filters (including regex) to improve your RSS feeds.

How to set up RSS feeds in qBittorrent?

  • Go to qBittorrent > View > RSS Reader > RSS.
  • If you see “Fetching of RSS feeds is disabled now! You can enable it in application settings,” you’ll have to enable the fetching.

5. Smarter Bandwidth Control with qBittorrent

qBittorrent lets you control how your internet gets shared across torrents. A few quick tweaks can smooth out performance and keep your connection from getting hogged. Here’s how to fine-tune your setup:

a. Limit Peer Connections (Keep Things Stable)

Too many connections can slow your system—especially if you’re downloading a lot of torrents at once or using a lightweight device. To set limits:

  • Go to Tools > Preferences (or Options) > BitTorrent
  • Under Connection Limits, adjust:
    • Global connections: Try 200–500 based on your system
    • Connections per torrent: Aim for 50–100
    • Global upload slots: Start with 4–8
    • Upload slots per torrent: Use 2–4
qBittorrent Bandwidth Management

b. Set Queueing Rules (Work Smarter, Not Harder)

Too many active torrents can drain your bandwidth. Queueing keeps it efficient. To set it up:

  • Go to Preferences (or Options)> BitTorrent > Queueing
  • Turn on “Enable torrent queueing”
  • Set your limits:
    • Active downloads: 3–5
    • Active uploads: 2–4
    • Total active torrents: 5–10
💡 Tip: Turn on “Do not count slow torrents” to let sluggish ones run quietly in the background.
qBittorrent Bandwidth Management

c. Schedule Bandwidth Use (Day vs. Night Control)

Torrenting while you sleep? Sounds good, right? Or simply, you might just want to free up bandwidth when others are online. The scheduler helps. To set it:

  • Go to Preferences (or Options) > Speed
  • Enable “Schedule the use of alternative rate limits”
  • Set your standard and alternate bandwidth limits.
  • Use the Scheduler tab to pick when those limits kick in.
qBittorrent Bandwidth Management

Perfect if you’re on a shared connection or your ISP limits speed during peak hours.

6. Troubleshooting qBittorrent.

Below are three infamous qBittorrent issues with their possible solutions. The qBittorrent stalled, the qBittorrent I/O error, and the qBittorrent not downloading.

a. How to fix the qBittorrent stalled?

If you see “stalled” as the status on your download, it means that qBittorrent is trying to download but can’t find seeders or all your connected peers cannot seed to you. To solve the qBittorrent stalled, you can try the following solutions.

  • Remove the torrent from the list and load it again. You can also try removing the torrent from the list without removing the content and then adding it again.
  • Run qBittorrent as an administrator. Exit qBittorrent; when opening it again, right-click and choose “Open as an administrator.”
  • Force resume or “set location.” If you paused the torrent and it stayed as “stalled, ” you’ll need to force its resume. You can also help qBittorrent locate the file by right-clicking and then “set location” to set the correct location where the torrent is being downloaded.
  • Update your tracker list or update a not-responding tracker. Right-click on your stalled torrent, go to edit trackers and paste working trackers (which you can find online by looking for tracker lists) after the ones already on the list. You can also edit one on the list if its URL is incorrect.
  • Other causes: The disk might be full, there are no seeders available, or the application is too old (update it to the latest version).

qBittorrent Stalled? Here’s how to fix it

Torrents stuck on “Stalled”? This guide breaks down the reasons and shows how to get things moving again — port settings, trackers, and more.

b. How to fix qBittorrent I/O error?

The qBittorrent I/O error might be caused by limited permission access or denied access from an antivirus or firewall. To fix the I/O error qBittorrent, try the following solutions:

  • Run qBittorrent as an administrator. Exit qBittorrent. Right-click and choose “Open as an administrator” when opening it again.
  • Create a user just for qBittorrent. Right-click on the qBittorrent application’s icon. Select properties > Security > Edit. Click on “Add”> enter the username. Click on “Check Names”> select your new user and click on “Ok.”
  • Add an exception to your antivirus (AV) and a firewall. As a test, disable your AV and firewall and check whether you keep seeing the qBittorrent I/O error. If not, you’ll need to create an exception on any of the programs causing the error. Don’t forget to enable your AV and firewall again.

c. qBittorrent not downloading

The qBittorrent not downloading might be caused by many reasons. If you cannot download with qBittorrent, try any of the following solutions.

  • Ensure that the torrent you are trying to download is healthy and alive. Check its peers using the bottom window. You can also check your trackers; and update them from a trusted list of trackers (if necessary). As a test, you can try downloading reliable torrents such as Ubuntu’s (https://ubuntu.com/download/alternative-downloads).
  • Connect via VPN. If your connection is being throttled, using a VPN might help you connect to your peers. If you are using a VPN but still unable to connect, try re-installing your VPN client or updating it. But if you can’t still connect via VPN, open qBittorrent settings > Advanced > On “Network Interface,” choose the interface assigned by the VPN.
  • Check your proxy config settings. Make sure the IP address, port, and proxy type are correct. If you are using SOCKS5, you will have to check the authentication. But if you cannot download with qBittorrent, try disabling the proxy.
  • Ensure the firewall or A/V is not blocking the connection. As a test, disable your AV and firewall and check whether you keep seeing the qBittorrent I/O error. If not, you’ll need to create an exception on any of the programs causing the error. Always enable your firewall and AV after you finish testing.
  • Downgrade. As a last resort, try downgrading your qBittorrent version. Some users report having to downgrade to older versions (i.e., 3.3.11)

d. Fix qBittorrent Freezing or Crashing

If qBittorrent freezes or crashes, it’s usually a memory or display issue—especially on low-power machines or high-res screens. Here are two quick fixes:

  • Tweak the disk cache: A bloated cache can make qBittorrent act weird—freezes or crashes. Adjusting the cache size can help. To do this, go to Tools > Preferences (Options) > Advanced > Scroll to Disk cache. If set to “Auto,” try a manual size—512MB or 1024MB. If it’s already high and causing trouble, switch back to Auto or lower it
  • Turn off high-res scaling: The UI might stutter or crash due to scaling conflicts (especially if used with a high-DPI display). How to fix it fast? Go to Properties (Options) > Compatibility > Change high DPI settings > Check “Override high DPI scaling” > Set it to “System” or “System (Enhanced)” > Click OK and restart qBittorrent

7. qBittorrent Frequently Asked Questions (FAQ.)

What are the best qBittorrent settings for faster downloads?

To get faster downloads, use a healthy torrent with plenty of seeders, enable DHT and PEX, choose a high-range random port (49160–65534), and ensure your upload speed is not capped. Also, allow UPnP or configure manual port forwarding.

Why is qBittorrent not downloading even with active torrents?

Common reasons include ISP throttling, blocked ports, an inactive tracker, or a misconfigured proxy or VPN. To fix this, try disabling your firewall temporarily or using a different port. We also recommend switching to a VPN with P2P support to see if the issue resolves.

How do I bypass ISP blocking with qBittorrent?

To bypass ISP blocking, choose a custom port. As a rule of thumb, always avoid default BitTorrent ports. ISPs often throttle or block common torrent traffic, so switching to a VPN with torrent support or simply using a seedbox can significantly improve speed and privacy. We also recommend a VPN with the kill-switch functionality

What port should I use in qBittorrent for optimal speed?

Use a port between 49160 and 65534. Also don’t forget to check if it’s open using tools like Portchecker. Avoid well-known torrent ports that ISPs may block. Also, try enabling UPnP/NAT-PMP if supported by your router, or set up manual port forwarding for best results.

Is it better to use a proxy or VPN for torrenting with qBittorrent?

Use a SOCKS5 proxy if you want faster speeds and don’t require full encryption. But, on the other hand, use a VPN if you need privacy and want to encrypt all your traffic. Learn more differences here: VPNs vs. Proxies

How do I enable the anonymous mode in qBittorrent?

Go to Preferences > BitTorrent > Privacy and check the box for “Enable Anonymous Mode.” This feature helps hide your client’s metadata. Only use this mode with public trackers — enabling it on private trackers can cause connection issues.

How can I use qBittorrent remotely?

Enable the Web UI in Preferences > Web UI. Then (on the same menu) set a username and strong password, and optionally restrict access to certain IPs. You can also use mobile apps like qBittorrent Controller or qBittorrent Remote to manage downloads on the go.

What should I do if qBittorrent is showing a stalled status?

Try these fixes: restart the torrent, check for available seeders, force resume, update your tracker list, and ensure your port is open. Also, confirm your storage device isn’t full or write-protected. Learn more on how to fix the qBittorrent stalled status

How can I throttle bandwidth in qBittorrent?

Under Preferences > Speed, set download and upload limits manually or schedule alternative rate limits for specific times of the day. This helps prevent qBittorrent from hogging all your bandwidth during peak usage times.

Is qBittorent Safe?

Yes, qBittorrent has always been considered one of the safest torrent clients on the market and still is today. The platform is open-source, free of ads, and free of bloatware.
