Share documents, not secrets.

Blackbox finds names, IDs, card numbers, API keys and hidden metadata in your files, lets you review every finding, and produces a truly redacted copy — verified, with an audit trail.

Why it is safe to share the output

True redaction

Text and image pixels under a redaction are removed from the file, not hidden behind a black box you can copy through.

Blurs every personal detail

Names, addresses, emails, phone numbers, Aadhaar, PAN, cards, bank details, API keys — and faces in photos — blurred irreversibly.

Hidden data scrubbed

Author fields, tracked changes, comments, hidden sheets, thumbnails, PDF XMP, and photo EXIF/GPS.

Verified & audited

The output is re-opened and re-scanned for every redacted value. You get a JSON audit report with hashes — no raw values.
