Why these tools run in your browser
A privacy-first design decision, not a limitation.
Files never leave your device
Every tool here runs as JavaScript in the tab you already have open. There is no upload endpoint, so there is nothing to intercept — a hotel Wi-Fi network cannot see what you convert.
Works when the internet does not
Load the page once and the tools keep responding on a plane, in a tunnel, or on a connection that has dropped. Latency is measured in milliseconds because there is no server round trip.
No account, no quota, no email
We do not ask for an email address, and there is no daily limit to hit. Open as many files as your device can hold in memory.

We ship a new utility every couple of weeks. If something is missing, tell us and it may land in the next batch.
