About resizing an image

Resizing changes an image's pixel dimensions — to meet an upload limit that caps width and height, fit a layout, or cut the file size of an oversized photo from a phone.

You set the target size (with or without keeping the aspect ratio) and the image is redrawn at those dimensions in your browser. Making an image larger than its original can't add detail that wasn't captured. Everything stays local.

How to Resize Image

  1. 1

    Add your image

    Drop in any image; it is processed entirely on your device.

  2. 2

    Set the new size

    Type an exact width and height, or drag the slider to scale by percentage. Keep the lock on and the other dimension follows the aspect ratio automatically.

  3. 3

    Download

    Save the resized image at its new dimensions.

Resize Image — frequently asked questions

Will resizing distort my image?+

Only if you want it to. Leave the aspect-ratio lock on and setting one dimension fills in the other automatically. Turn the lock off to force an exact width and height, which can stretch the image.

Can I set an exact width and height?+

Yes — type both values in the Width and Height fields. Turn off the lock icon between them first if the exact size doesn't match the original proportions.

Can I enlarge an image?+

You can, but upscaling past the original size cannot add detail — the result will look soft.

What output format do I get?+

The same format as the input (JPG stays JPG, PNG stays PNG, WebP stays WebP).

Is there a free way to resize an image by pixels or percentage?+

Yes — this tool resizes the image entirely in your browser, free and with nothing uploaded.

Do you upload my files to a server?+

No — every tool here processes your files entirely on your device, and nothing is uploaded to a server. The only exception is the AI tools, which send the extracted text (not the file) to Claude to do their work.

Is there a file size limit?+

There's no artificial limit we impose, but since processing happens in your browser, very large files (500+ MB or 1,000+ pages) are limited by your device's memory rather than by us.
