What it does

Set an exact width and height in pixels, or scale by a percentage. Resize one photo or a whole batch, keep the aspect ratio so nothing looks stretched, and download everything as a ZIP. Your images stay on your device.

How to use it

  1. Click “Choose images”, drop one or more images onto the box, or paste with Ctrl+V (⌘+V on a Mac).
  2. Choose “By pixels” and enter a width, a height or both, or choose “By percentage” and pick a scale. Leave “Keep aspect ratio” on unless you want an exact stretch.
  3. Pick the output format. Changing any setting updates every image instantly.
  4. Download the images one by one, or all at once as a ZIP.

Common uses

  • Shrinking camera photos before emailing or uploading them
  • Making a batch of product photos the same width for a shop or blog
  • Meeting a form’s exact pixel requirement, such as 600 × 600

Tips

  • Resize before you compress: fewer pixels is the most effective way to cut file size.
  • For photos with different shapes, enter only the width (or only the height) so each one keeps its proportions.
  • Avoid enlarging small images by more than about two times, since detail can’t be added back.

Questions

How does “Keep aspect ratio” work when I enter both width and height?

The image is scaled to fit inside the box you enter, so it never looks stretched. One side may come out smaller than the number you typed.

Can I make an image bigger?

Yes, but enlarging can’t add detail that isn’t there, so large increases will look soft.

Is there a maximum size?

Results are capped at about 16.7 megapixels (for example 4096 × 4096 px), the largest size every major browser can handle safely.
