Resize Image
Resize an image to exact pixel dimensions, keeping the aspect ratio locked if you want.
Free No signup Runs in your browser — nothing uploaded
What it does
Resize Image works on JPG, PNG and WEBP images and writes a new file; the one you dropped in is untouched. Change image dimensions instantly.
When you need it
Usually because something downstream has an opinion: a profile photo that must be square, a marketplace that rejects anything over a certain width, a print that needs the right proportions, or a phone photo that arrived rotated.
Limits and caveats
Enlarging an image cannot add detail that was never captured, so scaling up softens it. Saving to a lossy format re-encodes the pixels, which is worth doing once rather than repeatedly on the same file. Everything happens in your browser, so the file never leaves your device.
