Privacy is not a feature. It's the foundation.
No Uploads
Everything happens locally in your browser. Your files are never sent anywhere.
No Tracking
No analytics, no cookies, no fingerprinting. We don't know what you convert.
100% Free
No paywalls, no premium tiers, no ads. Free and open for everyone.
No Account Required
Just open the page and start converting. No sign-ups, no emails, no friction.
How does it work?
All conversions happen using WebAssembly and browser APIs. Your files are processed entirely in-memory on your device and are never sent to any server. The conversion code runs locally in your browser — no backend, no cloud, no network requests. When you close the tab, the data is gone.
