How To Enlarge A Photo For Printing Without Losing Quality

Your computer's native photo editing tools are generally all you need to adjust DPI and get your photo ready for print. (If you have Photoshop or other similar photo editing software, we'll get into some additional things you can do later in this post.) Tuning DPI will also show you the largest size at which you can keep the original quality of your photo.

  1. Double-click your file to open it in preview. (To open multiple images, highlight them all, right click, and click "open.")
  2. In the menu bar, click on "Tools".
  3. Select "Adjust Size" in the "Tools" dropdown menu. (You should now see adjustable cells for Width, Height, and Resolution show up.)
  4. Choose "inches" for Width and Height and "pixels/inch" for Resolution. (For our purposes we can treat pixels/inch and DPI as one and the same.)
  5. Uncheck the “Resample Image” checkbox and set your Resolution to 300 pixels/inch. The dimensions for your maximum Width and Height at 300 DPI will appear automatically.
  6. Once you resize your image to your liking, click okay and save the file. (Don't worry about getting the aspect ratio just right, you can easily crop in our editor!)
