Resize Image

Change image dimensions with aspect ratio control

About Resize Image

Change an image's pixel dimensions to fit a specific requirement — a profile photo size, a form's upload spec, or a smaller thumbnail for a webpage — while keeping the proportions correct.

How to resize image

  1. 1Upload the image you want to resize.
  2. 2Enter the target width and/or height, with aspect ratio locking available if you only want to set one dimension.
  3. 3Click Run Resize Image.
  4. 4Download the resized image.

Tips

Lock the aspect ratio unless you specifically need to stretch or squash the image — it avoids distorted results.

If a site or form specifies exact pixel dimensions, resize to those numbers precisely rather than guessing.

Resizing down also reduces file size, so it can double as a lighter version of Compress Image for oversized photos.
