How to use it

  1. Choose an image by dropping it in the box or browsing your files.
  2. Set the new size in pixels or as a percentage. With “Keep aspect ratio” on, changing one side updates the other.
  3. Resize and download. Pick the output format first if you want to change it.

Examples

  • A 4000 × 3000 photo at 25% becomes 1000 × 750.
  • Set the width to 1200 and the height follows automatically.

Making an image larger cannot add detail, so it may look soft. JPG output replaces transparent areas with white. Animated images are saved as a single frame.
