FAQ

Is this really secure?

Yes. Files are overwritten with cryptographically random data before deletion. Even professional data recovery tools cannot restore overwritten data on flash drives and HDDs.

Why not just delete files normally?

Normal deletion only removes the file entry from the directory — the actual data remains on the drive and can be easily recovered with tools like Recuva or PhotoRec.

How many passes do I need?

For flash drives and SSDs, 1 random pass is sufficient. For older HDDs, 3 passes (DoD standard) provides strong protection. 7 passes (Gutmann) is for maximum paranoia.

Does this work on SSDs?

Yes, but SSDs use wear-leveling which may retain data in spare blocks. For SSDs, the drive manufacturer's secure erase tool is more thorough. This tool is most effective on USB flash drives and HDDs.

Why does it need Chrome or Edge?

The tool uses the File System Access API to write directly to your drive. This API is currently only available in Chromium-based browsers (Chrome, Edge, Brave).

What is the erasure certificate?

A downloadable document confirming the wipe: date/time, method used, number of files erased, total data size, and pass count. Useful for compliance and auditing.
