Good to know
With the aspect ratio locked, changing the width or the height works out the other side from the original proportions, so the picture is never squashed or stretched.
If you enlarge past the original size, the tool warns that the picture may turn blurry: enlarging spreads the existing pixels apart and does not add new detail.
Which images work
JPG, PNG and WebP images are supported, up to 50 MB per file and 40 megapixels. Animated images such as GIFs can't be edited; use a still image instead.
Images with a wide-gamut (Display P3) or CMYK color profile open too, with colors converted correctly; CMYK images are limited to 24 megapixels.
FAQ
- A site says my image is too big. What should I do?
- Make the width and height smaller and save again; the file usually gets much smaller. To shrink it further, use Convert format afterwards and lower the JPEG or WebP quality.
- Is my image uploaded?
- No. This tool works on the image right in your browser; it is not sent to our servers or to any other service.
- Does it cost anything?
- This tool is free to use.
