Exact pixel dimensions
Type any width and height up to 12,000 px per side — perfect for hitting a required size to the pixel.
Aspect ratio lock
Change one side and the other updates automatically, so nothing ends up stretched or squashed.
JPEG, PNG, and WebP
Open any of the three and save in any of the three. PNG and WebP keep transparent backgrounds intact.
Need a smaller file too?
Once the dimensions are right, run the result through Compress Image to cut the JPEG or WebP file size even further.
