a→b
Privacy

Your files never leave your device.

This isn’t a policy you have to trust — it’s something you can watch happen. Here’s exactly what a → b does, and how to verify it yourself in about ten seconds.

Processed on-device
Every byte is handled by your own CPU via WebAssembly — never a server.
Nothing is logged
No analytics, no cookies, no fingerprinting. We keep nothing because we receive nothing.
Verifiable, not promised
The zero-requests claim is something you can watch in DevTools, not a policy to trust.
Verify it yourself
Open your Network tab and watch nothing happen.
Press F12 (or ⌥⌘I), open Network, then run any conversion. The request list stays empty — because there’s no server to call.
