Compare Two Images

Highlight where two versions of an image differ. Nothing is uploaded.

Choose both images to compare them.

Spot the differences

Useful for checking a design before and after an edit, comparing two scans, or finding changes between versions of a screenshot. Changed pixels turn red, and the rest of image A fades into the background.

Questions

Do the images have to be the same size?

Yes for the comparison to be exact. If the sizes differ, image B is scaled to match image A.

Is my image uploaded?

No. The comparison runs in your browser.
