Frequently Asked Questions

Does compressing a PNG keep transparency?

Yes. Alpha transparency is preserved through quantization, so logos and screenshots keep their transparent backgrounds.

How does PNG compression work here?

The image's colours are reduced to an optimized palette (quantization), which typically cuts screenshots and graphics by 50–80% with no visible difference.

Are my images uploaded?

No. Compression runs entirely in your browser — images never leave your device.
