How it works

  1. Your browser decodes the image and reads its original dimensions.
  2. It redraws the image at the new size using high-quality resampling, in several steps for large reductions so edges stay sharp.
  3. The resized file is saved in the format you choose.

Supported formats

Opens
JPG, PNG, WebP, AVIF, BMP and GIF (the first frame of an animation)
Saves
The same format, or JPG, PNG or WebP
Limits
Files up to 80 MB. The saved image can be up to 16.7 megapixels on iPhone and iPad, 36 on Android and 64 on computers, and 16,384 pixels on its longest side.
  • Making an image much larger than the original can’t add detail, so it will look soft.
  • Metadata such as camera details and location is not copied to the new file.

Your image stays on your device

This tool runs entirely in your browser. The image is never uploaded, so there is nothing for us to store, see or delete.

To check, open your browser’s developer tools, switch to the Network tab and use the tool: you will not see your image being sent anywhere.

Questions

Are my images uploaded anywhere?

No. The image is read and processed by your own browser. Nothing is sent to our servers, so there is no copy of your image anywhere but your own device.

Will enlarging an image make it sharper?

No. Enlarging adds pixels but cannot add detail, so large upscales look soft. Resizing down always looks better than resizing up.

Can I change the aspect ratio?

Yes. Unlock the link between width and height, then set both. The image will be stretched to fit — it is not cropped.
