Resize for the right place
Different destinations want different dimensions: a profile picture might need to be square, a header image a specific width, and an upload form may reject anything above a certain size. Resizing to the exact pixels the destination expects avoids awkward cropping and cuts the file size, which speeds up loading. Locking the aspect ratio keeps the image looking natural while you change one dimension; unlocking it lets you hit precise width-and-height targets when a layout demands them. Everything happens on your device, so the original never leaves your browser.
Common uses
- Resizing a photo to the exact dimensions a website or form requires.
- Shrinking a large image's pixel dimensions to reduce its file size.
- Making a square crop-free version for an avatar or thumbnail.
Frequently asked questions
- Are my images uploaded?
- No — resizing happens entirely in your browser; nothing is sent to a server.
- Should I keep the aspect ratio locked?
- Usually yes — locking it changes width and height together so the image doesn't look stretched. Unlock it only when you deliberately need to force exact dimensions.
