TinyPNG alternative that never uploads your photos

TinyPNG is fast but sends files to a third party with size and count limits. Compresso runs entirely in your browser — verify zero upload bytes in DevTools.

Cómo funciona

1. Open the Compresso app
2. Drop images — no account
3. Download optimized files locally

Preguntas comunes
