Private by design

Your files never leave your device

Most online PDF sites upload your documents to their servers. DocuVault doesn’t. Everything happens inside your browser, so there is nothing for anyone to see, store or leak.

Check it yourself

Use a tool once, then turn off your Wi-Fi or switch to airplane mode and use it again — it still works. Developers can watch the Network tab: no file is ever sent.

How we keep DocuVault private and free

  1. Step 1

    You choose a file

    Your browser opens it directly from your device — like opening it in an app.

  2. Step 2

    Your device does the work

    The processing code runs inside this browser tab. No server ever receives your file.

  3. Step 3

    You save the result

    The new file goes straight to your downloads. Close the tab and everything is gone.
