About Resize Image

Change image dimensions in seconds with this in-browser image resizer. Set an exact width and height, lock the aspect ratio, or scale a photo down by percentage — the original format is preserved so you get back the same kind of file, just bigger or smaller.

The resize happens entirely on your device with no upload and no signup, and it works offline. Whether you're shrinking a photo for email or fitting an image to a layout, your files never leave your browser.
