A letter to anyone who has ever paused before uploading a file.

You know the moment. You have a PDF that matters. Maybe it's a signed contract, a payslip, a medical scan, a photo of your passport. And you just need to do one small thing to it. Merge it. Shrink it. Pull the text out. So you search, you land on some free online converter, you choose your file, and then you stop.

Where is it actually going? Whose server does it land on? How long do they keep it? Who else gets to read it? You don't know, and nobody tells you. That little pause you feel is completely reasonable, and honestly, it's the whole reason I built DoxDock.

So I made the opposite kind of tool. In DoxDock, nothing you open ever leaves your machine. There's no upload. There's no server sitting somewhere waiting for your document. No accounts, no sign-ups, no trackers, no analytics quietly writing down what you do. Every conversion happens right inside your own browser, on your own device, using your own processor. Your file is opened, worked on, and handed straight back to you. It never once touches the network.

I didn't want you to have to trust me on that. Trust is what every other tool asks for, and trust is exactly the thing you can't actually check. So I built DoxDock to be provable instead.

Don't trust me. Check.

Open your browser's Network tab and use any tool. You'll see requests only to the app itself, never to an outside server.
Or turn off your Wi-Fi entirely and reload. Everything still works, offline, for as long as you like.
Or read the code. It's open source under the MIT license, and the rule that forbids any network request, connect-src 'self', is sitting right there in the page's security policy.

The whole thing is free and open source, and that part is deliberate too. Privacy shouldn't be a premium tier. A tool that touches your most private documents should be one that you, or anyone cleverer than me, can open up, read, audit, fork, and run yourself. If you don't believe the promise, you should be able to prove it false. I'm quietly confident you can't.

That's really the whole idea. Useful tools shouldn't cost you your privacy. The safest place for your files is the device already in your hands. And any software that makes a promise about your data should let you check it for yourself instead of asking you to just believe.

So please, use it. Try to break it. Tell me where it falls short, or send a pull request and make it better. It's as much yours as mine now.
