Your PDF looks redacted. Is it really?
Black boxes and highlights often leave the original text sitting right underneath — recoverable with copy-paste or pdftotext. Drop a file below and we'll check the text layer and the usual leak surfaces. We never store your file or show the recovered text.
(Bot-check not configured — dev mode)
Three steps, nothing stored.
Drag in any PDF you're about to share. It's analyzed in memory and discarded — no account, no storage, no copy kept.
Live text under dark covers and un-applied redactions, plus embedded files, comments, form values, document scripts, and earlier saved revisions.
Recoverable or not — with the exact limits of the check spelled out. The recovered text itself is never returned to anyone.
What it catches — and what it can't.
- Text left live under black or dark opaque boxes
- Redaction annotations that were never applied
- Black boxes pasted in as images
- Metadata, embedded files, comments, form values & earlier revisions
- Text hidden under light-coloured or see-through covers
- Text baked into a page image (that needs OCR)
- Whether a redaction was the right call in the first place
Treat this as a fast safety check, not a sign-off. A result of “no recoverable text detected” means we didn't find a leak we look for — not that the document is guaranteed clean.
Found something? Redact it properly.
Lacuna removes text from the PDF's text layer — not just a box over the top — and logs every decision in a hash-chained, tamper-evident audit log.
