Frequently Asked Questions

Will my images lose quality?

Our smart compression algorithm removes unnecessary metadata and optimizes color profiles. If you keep the quality slider above 75%, the human eye generally cannot detect any loss in quality.

Are my images safe?

Yes. Since our tool is 100% browser-based, your images never leave your computer. We do not store, view, or upload your private photos.
