How to use Resize Image

  4. Click “Resize images” and download the results.

Frequently asked questions

Will my image be stretched?

Not with “Keep aspect ratio” turned on. Each image is scaled to fit inside the size you set, keeping its proportions.

Can I make an image bigger?

Yes — untick “Don't enlarge”. Enlarging cannot add detail, so very large increases will look soft.

Is Resize Image free?

Yes. Resize Image is free to use with no sign-up and no watermark.

Are my files uploaded to your server?

No. All processing happens locally in your browser using JavaScript and WebAssembly. Your files never leave your device, which also makes it fast and private.

Does it work on my phone?

Yes. It works in any modern browser on Windows, Mac, Linux, Android and iPhone. Very large files may be slow on older phones.
