review suggestions before applying redaction | RedactionPDF
What is PDF redaction?
PDF redaction means permanently removing sensitive information from a PDF before you share, file, upload, or archive it. This ensures private data is fully gone from the document, not just hidden.
Is redaction different from blacking out text?
Yes. A black box overlay only hides text visually, while proper PDF redaction actually removes the content from the file itself—so it can't be searched, copied, or recovered.
Can RedactionPDF automatically detect sensitive data?
RedactionPDF can identify common sensitive patterns in text-based PDFs, like email addresses, phone numbers, Aadhaar numbers, PAN numbers, IP addresses, credit card numbers, IBANs, and other labeled IDs. You can review and approve each suggestion before applying the redaction.
Does RedactionPDF remove PDF metadata?
Yes. RedactionPDF clears standard PDF metadata—including author names, creator software, timestamps, subjects, keywords, and custom metadata fields—during the redaction process.
Does RedactionPDF support scanned PDFs?
Auto-detection works best with text-based PDFs. For scanned or image-based PDFs, you can still mark and redact visible areas manually.
How long are files retained?
Original PDFs are deleted immediately after processing. Your redacted PDFs stay available for up to 1 hour.
Is my data used for AI training?
No. RedactionPDF never uses uploaded documents to train AI models, and no human ever reviews your files.
