Tools

Three tools, done properly

Each one does a single job well, on your device.

How it works

Your file stays in the tab

Every tool runs on your device: the code comes to your file, not the other way round.

  1. 01

    Open a file

    The PDF is read into this browser tab's memory. Nothing is uploaded.

  2. 02

    Process on your device

    PDF work and the detection model run in a background worker, so the page stays responsive.

  3. 03

    Save the result

    The new file is built in the tab and downloaded. Close the tab and it's gone.

FAQ

Questions

How can I check that my file isn't uploaded?
Open your browser's DevTools, switch to the Network tab and run a tool. You'll see the page and its code load, and no request carrying your file.
Is redaction permanent?
Yes. The selected text is removed from the PDF itself, not covered with a black box that can be copied from underneath.
Does it work offline?
Once a tool has loaded, it keeps working without a connection. The detection model is cached after the first use.
What does it cost?
Nothing. There are no accounts, limits or watermarks.

Your files are nobody's business.

Start with the redactor: open a PDF and see what it finds.
