Hi everyone 👋

I built Brevio because almost every "online" PDF or image tool uploads your
file to a server first. For anything sensitive — a contract, an ID scan, a
medical PDF — that never sat right with me. So Brevio does the opposite: every
tool runs entirely in your browser. Your files never leave your device, and you
can verify it in ~10 seconds by opening DevTools → Network and watching that
nothing is sent.

It's now 500+ tools (PDF, image, dev, text, calculators), no account, no
per-hour limits, works offline after the first load, and it's localized into 14
languages.

It's free, supported by contextual ads. The one thing I'd love feedback on:
try to catch anything that touches the network when it shouldn't — that's the
bug I most want to hear about.

Thanks for taking a look!
