How it works

  1. 1

    Paste the original filename

    Anything from "john_smith_passport_scan.pdf" to a camera default.

  2. 2

    Get a random replacement

    The extension is kept so the file still opens correctly.

  3. 3

    Regenerate if needed

    Click Regenerate for a different random name.

FAQ

Why would a filename need cleaning?
A filename itself can carry identifying information - a real name, a date, a device pattern - even after the file content and its metadata have been cleaned up separately.
Does this rename the actual file?
No - it only generates a suggested new name as text. Save/rename the file yourself using that name.
Does this tool upload my filename anywhere?
No - the random name is generated entirely in your browser.
