Batch image resizer

Resize many images at once — fit inside a box, scale by percent, or set the long side — downloaded as one ZIP.

Images stay in this browser. Nothing is uploaded or stored.

Up to 20 PNG/JPG/WebP files (≤ 10 MiB each). Output is a ZIP built in memory — combined output is capped at 96 MiB. Fit and long-side modes only shrink; percent mode also enlarges. Animated images lose animation.

How to use

  1. Choose up to 20 images.
  2. Pick the resize mode, target size, and output format.
  3. Download the ZIP of resized images.
