Image Resizer

Resize any image by width, height, exact size or percentage — with the aspect ratio kept.

How to use

  1. Choose any image from your device.
  2. Pick how to resize: by width, by height, by percent, or an exact width × height.
  3. Keep “Keep aspect ratio” on to avoid stretching, then click “Resize image” and download the result.

FAQ

Will resizing keep my image proportions?

Yes, when Keep aspect ratio is on, the other side is calculated automatically so the image is never stretched or squashed. Turn it off only when you want an exact size.

Can I resize by percentage?

Yes. Choose Resize by percent and enter a value: 50 makes the image half its original size, 200 doubles it.

Does resizing change the image format?

Only if you choose a different output format. Pick PNG, JPEG or WebP; JPEG fills transparent areas with white, while PNG and WebP keep transparency.

Are my images uploaded?

Never. The resizing happens entirely in your browser.
