Is Compresso really free?

Yes. Compresso is free with no sign-up, no paywall, and no watermarks on your files.

Does Compresso upload my files?

No — never. Everything runs 100% on your device. Compresso works fully offline; your files never leave your phone.

Images (JPG, PNG, HEIC, WebP), PDFs, and video. Output images as WebP (smallest, transparency), JPG (max compatibility), or keep the original format.

Completely. There are no servers involved, so it works on a plane, in a tunnel, anywhere — and it is private by design.

None. Your compressed files come out clean — no badges, no branding.

Yes. Convert Video to GIF or Video to Images with trim, fps, and presets, plus a live size estimate before you export.
