How it works

Three steps, zero uploads.

  1. 01

    Drop a file

    Pick a tool and drag your file in. Nothing is sent over the network.

  2. 02

    Processed on your device

    The browser does the work with the File API, WebAssembly and Web Workers — the same machine you are sitting at.

  3. 03

    Download the clean file

    You get a new file with the sensitive parts removed. The original is untouched.

Verify it yourself: open any tool, switch off your network, and it still works.
