Are my images uploaded to your server?

No. The tool runs entirely in your browser, so your images never leave your device. That also makes it fast and works for private photos.

How much smaller will my image get?

Phone photos usually shrink by 50–80% at 75% quality. Images that are already compressed shrink less.

PNG is lossless. For a much smaller file, switch the output to JPG or WebP.

Lower the quality and, if needed, resize the image first with the Image Resizer. Smaller dimensions cut the size the most.
