When do you need to resize an image?

A government form asking for a "300×300 pixel photo," a website banner with a fixed slot, a smaller image for email — exact dimensions come up everywhere. Keep aspect-ratio lock on and your image won't distort: change the width and the height adjusts proportionally on its own. Shrinking a large image keeps quality intact; blowing up a small one too far can look blurry — for that, reach for our AI Upscaler (coming soon).

Frequently Asked Questions

What does aspect-ratio lock do?

It keeps the width-to-height ratio fixed — change one dimension and the other adjusts automatically, so your image never looks squashed or stretched. Turn the lock off if you need two exact, independent dimensions.

Which format should I download in?

WebP for the web (smallest file size), JPG for general use, PNG when you need a transparent background. Choosing "Original format" keeps it exactly as it was.

Does the image get sent to a server?

No — resizing happens entirely in your browser; the image is never uploaded anywhere.
