Frequently Asked Questions
What format will my compressed images be in?
WebP. This tool re-encodes PNG, JPG and WebP images to WebP, which is usually much smaller at similar quality. The dedicated JPG and PNG compressors keep their original formats instead.
Where does my image compression happen?
On your device. Compression runs locally in your browser with WebAssembly, and your images are never uploaded anywhere. Open DevTools → Network while compressing to confirm.
Can I convert multiple images at once?
Yes — use Image Factory to build a batch pipeline: convert, compress, crop and resize many images in one flow, entirely on your device.
