Automatically Find Common Sensitive Data in Text-Based PDFs
RedactionPDF can suggest emails, phone numbers, SSNs, IP addresses, credit cards, IBANs, routing numbers, and labelled IDs in text-based PDFs. You review every suggestion before applying redaction.
Automatic detection works best with text-based PDFs. For scanned or image-based PDFs, you can still redact visible areas manually.
Why Black Boxes Are Not Enough
Adding a black rectangle over text may not remove the underlying PDF content. True redaction should remove selected content from the output PDF so it is no longer searchable or copyable.
Secure PDF Redaction Workflow
Files are uploaded over HTTPS and processed temporarily for redaction. Original PDFs are deleted after processing, and redacted PDFs stay available for up to 1 hour. RedactionPDF does not use uploaded documents to train AI models or manually review your files.

review suggestions before applying redaction | RedactionPDF
What is PDF redaction?
PDF redaction permanently strips selected sensitive content from a file before you share, file, upload, or archive it — nothing is left behind.
Is redaction different from blacking out text?
Yes. A black box overlay only hides text visually. Real PDF redaction actually removes the selected content from the output file, so it can't be searched, copied, or extracted.
Can RedactionPDF automatically detect sensitive data?
RedactionPDF can detect common sensitive data in text-based PDFs — emails, phone numbers, tax file numbers, IP addresses, credit cards, IBANs, routing numbers, and labelled IDs. You review each suggestion before redaction is applied.
Does RedactionPDF remove PDF metadata?
Yes. RedactionPDF scrubs standard PDF metadata — author, creator, timestamps, subject, keywords, and custom fields — during processing so your document leaves no digital footprint.
Does RedactionPDF support scanned PDFs?
Auto-detection works best on text-based PDFs. For scanned or image-based files you can still manually redact any visible area.
How long are my files kept?
Original files are deleted immediately after processing. Your redacted PDF stays available for up to 1 hour before it's removed.
Is my data used for AI training?
No. RedactionPDF does not use uploaded documents to train AI models. No human ever reviews your files.
