Choose Manual Redaction or Auto-Detection with Review
Use manual removal to block out any visible area, or enable auto detection to highlight common sensitive patterns for your review before confirming.
Manual Redaction
Draw boxes over names, signatures, account numbers, and any visible area you want to remove. Works on any PDF type.
Auto Detection
Review detected emails, phone numbers, SSNs, IP addresses, credit cards, IBANs, routing numbers, and labeled IDs in text-based PDFs.
Automatically Find Sensitive Data Like Email IDs and Phone Numbers in PDFs
RedactionPDF can detect emails, phone numbers, SSNs, IP addresses, credit cards, IBANs, routing numbers, and labeled IDs in text-based PDFs. You review each detection before applying removal.
Auto-detection works best on text-based PDFs. For scanned or image-based PDFs, you can still manually redact visible areas.
Why Black Boxes Fall Short
Covering text with a black rectangle may not remove the underlying content. True redaction permanently removes selected content from the output PDF so it can no longer be searched or copied.

review suggestions before applying redaction | RedactionPDF
What is PDF redaction?
PDF redaction is the process of permanently removing selected sensitive content from a PDF before sharing it online, filing, uploading, or archiving the document.
Is PDF redaction different from just blacking out text?
Yes. A visual black box only covers text temporarily, while true PDF redaction removes selected content from the output file so it cannot be searched, copied, or extracted.
Can RedactionPDF automatically find sensitive data in my PDF?
Yes. RedactionPDF can detect common sensitive patterns in text-based PDFs, such as emails, phone numbers, SSNs, IP addresses, credit cards, IBANs, routing numbers, and labelled IDs. You review the suggestions before applying redaction.
Does RedactionPDF remove PDF metadata too?
Yes. RedactionPDF can clean standard PDF metadata such as author, creator, timestamps, subject, keywords, and custom metadata fields during processing.
Does RedactionPDF work with scanned PDFs?
Automatic detection works best on text-based PDFs. For scanned or image-based PDFs, you can still manually redact visible areas.
How long are my files kept on the server?
Original PDFs are deleted after processing. Redacted PDFs stay available for up to 1 hour.
Is my data used to train AI models?
No. RedactionPDF does not use uploaded documents to train AI models. No human review of your files takes place.
