How It Works Under the Hood
Why Redaction Is Permanent
We remove the underlying content from the PDF so it is no longer in the file. That is different from drawing a black box on top—true redaction deletes the data so copy-paste and extraction tools cannot recover it. Your file is processed on your device—redact pdf stays private.
How to Use Redact PDF in 3 Simple Steps
1. Upload Your PDF
Open the Redact PDF tool and add your file. The PDF is read on your device only. If the file is password-protected, unlock it first with our Unlock PDF tool, then redact the unlocked file.
2. Mark Areas to Redact
Select the text you want to remove or draw boxes over images or areas. Redaction permanently deletes that content from the file—it will not be recoverable. You can often search for a word and redact all occurrences. Double-check before applying.
For editing or covering content without permanent removal, you can use our PDF Editor (e.g. whiteout). Redaction is for when you need the data gone for good (e.g. GDPR, confidentiality).
3. Download Your Redacted PDF
Download the redacted PDF. The underlying data in the redacted areas is gone. Keep an unredacted backup if you might need it. To add a password before sharing, use our Protect PDF tool.
Who Is This Tool For?
Legal
Redact names, SSNs, or confidential clauses before sharing with opposing counsel.
HR
Remove employee PII from documents before archiving or sharing.
GDPR
Sanitize documents to remove personal data before transfer or publication.
Troubleshooting Common Issues
I cannot redact; the file seems locked.
Password-protected PDFs must be unlocked first. Use our Unlock PDF tool, then redact the unlocked file.
