3. 3Leave the lock on to keep the proportions, or turn it off to set both freely.
4. 4Download the resized image.

The image is drawn onto a canvas at the target size using the browser's built-in high-quality resampling, which averages neighbouring pixels rather than simply dropping them. That is what keeps a downsized photo smooth instead of jagged.

Making an image smaller is lossless in appearance — there is more information than you need, so removing some is safe. Making one larger cannot invent detail that was never captured, so enlarging past about 150% starts to look soft. When you scale up, the tool warns you.

With the aspect lock on, changing one dimension recalculates the other from the original ratio, so circles stay circular and faces are not squashed.

Images are decoded by the browser, redrawn on a canvas and re-encoded on your own machine. Nothing is uploaded, so there is no waiting on a queue and no copy of your photos anywhere else.
