Remove PII from a PDF automatically — and permanently
Sharing a document shouldn't mean sharing someone's Social Security number. Whether you're producing records for a case, sending a contract to a third party, or publishing a report, the personally identifiable information (PII) inside needs to come out first — and it needs to come out in a way that can't be undone with copy-paste.
What counts as PII in a document
- Social Security numbers — the highest-risk item in US documents
- Email addresses and phone numbers — direct contact details
- Credit and debit card numbers — a fraud risk in any shared file
- Names, addresses, dates of birth, account numbers — anything that identifies a person
Why deleting text isn't enough — and black boxes are worse
PDFs remember more than they show. A black rectangle drawn over text is just an annotation sitting on top; the text is still in the file and comes out with select-all. Court filings have leaked names exactly this way. Metadata is a second leak: author names, tracked changes, and hidden annotations travel with the file. Real PII removal destroys the content and strips the metadata.
Remove PII in three steps
- Drop your PDF on redactoronline.com. It opens in your browser only — no upload, no account. (Scanned document? Click “Scan (OCR)” first and the text is recognised on your device.)
- Click “Auto-detect PII”. The document is scanned locally for SSNs, email addresses, phone numbers, and card numbers (card candidates are checksum-validated so random long numbers aren't flagged). Every hit is marked in red for your review — add marks by dragging, remove any with a click, and use search for names the detector doesn't guess.
- Click “Redact & download”. Marked content is destroyed at the pixel level, pages are rebuilt, and metadata is stripped. The PII is gone from the file, not hidden in it.
Batch cleaning: drop several PDFs at once and Redactor Online will auto-detect and redact PII across all of them, then hand you a zip with a per-file report.
Common questions
Is automatic detection enough on its own? Treat it as a fast first pass. It reliably catches pattern-based PII (SSNs, emails, phones, cards), but names and free-text details need a human eye — that's why everything is marked for review before anything is destroyed.
Does my document get uploaded for scanning? No. Detection, OCR, and redaction all run inside your browser. Disconnect from the internet after the page loads and everything still works.
Can the redaction be reversed? No. The output contains flattened images with the marked regions destroyed. There is no layer to peel back and no hidden text to extract.
