Resize an image online
A 4000-pixel photo is wasted on an 800-pixel column. Resize first, then compress.
Set the max width or height. The tool scales the longest edge and then reduces file weight.
- Control the longest edge in pixels.
- Then compress so the resized file is light.
- Batch resize a folder before you publish.
Set the max edge, then select files. Scaling happens on your device.
Resize before you compress
Compression without resize still ships extra pixels. The browser must download those pixels.
Match the longest edge to the largest size you show on the site.
Suggested sizes
