Resize photos for web, email and social
Set a target width, height or percentage and the other side follows automatically, so nothing looks stretched. Transparent PNG and WebP images stay transparent. Resize many images at once and download them all as a ZIP.
Is the aspect ratio preserved?
Yes, always. Choose width or height and the other dimension is calculated for you.
Can I make an image bigger?
Untick “Don't enlarge small images”. Enlarging a small image will make it look soft, because no new detail can be created.
Are my images uploaded?
No. Everything happens in your browser.
