Friendly, privacy-first file tools for everyone.
Make your files fit, right in your browser. Your files never leave your device.
Simple tools for everyday file problems: the photo a form rejects for being too big, the video that will not send, the PDF that is too heavy for email. Built for people who have never heard the word "compression".
Available now: Compress image to a target size (20 KB, 50 KB, 100 KB or any limit you need). More tools are on the way.
- Private by design. Free tools run entirely in your browser. No upload, no copy kept on a server.
- Honest. You always see the real result, and we tell you before anything ever leaves your device.
- For everyone. Mobile first, accessible, and available in English and Portuguese, with more languages coming.
- Open core. The tools and the site are open source under AGPL-3.0.
