Redact PDF

Permanently remove sensitive text with visual redaction.

Guide & FAQ

About this tool

Permanently remove sensitive text and regions - account numbers, personal IDs, privileged lines - before FOIA response, discovery production, or public release. JoyPDF burns redaction into page content locally in your browser, not reversible highlight black boxes. Free, no account. Search-and-redact helps bulk PII; manual boxes handle irregular regions. Verify redacted copy can't select hidden text under black - test in Acrobat before release.

What you get
  • Permanent: content under redact box removed from PDF data - not recoverable via copy-paste.
  • Search: find strings like SSN patterns or names and redact occurrences batch-wise.
  • Manual: drag rectangles for irregular regions search misses.
  • Page scope: optional page ranges limit redaction pass to relevant sections.
  • vs highlight: black redaction bar destroys bytes - highlight would leak under select-all.
  • Limits: OCR text layer might retain copyable text if redaction doesn't hit text object - verify export.
When to use
  • FOIA and public records releases removing citizen PII.
  • Discovery productions withholding privileged paragraphs under meet-and-confer.
  • Publishing case studies redacting client names and figures.
  • Sharing medical PDFs externally with member IDs removed.

Common questions

Is JoyPDF redaction truly permanent?
JoyPDF redaction path removes content under marked regions in exported PDF rather than cosmetic overlay alone - designed so select-all and copy shouldn't recover redacted strings. Always verify redacted file yourself: try selecting under black bars, search for redacted name, use secondary PDF inspector. Redaction failures in industry history came from overlay-only tools - treat verification as mandatory legal QC step.
Can I redact by searching for a name?
Search redact finds text matches across pages - efficient for repeated client name or account number. Review each match before apply - similar names may false positive. Manual boxes catch logos and faces text search misses. Scanned PDFs need OCR PDF first or redact is image-box only over pixels.
Redact PDF vs black highlight in Edit PDF?
Edit PDF black shape might cover visually but leave text in file structure - FOIA reviewers reject that. Redact PDF destroys underlying content for release versions. Never ship highlight-as-redaction for legal disclosure.
Is my PDF uploaded during redaction?
No. Marking and burn run locally. Privileged discovery sets stay on counsel workstation - align with bar ethics on local vs cloud tools.
Should I redact before or after OCR?
Redact final release version after OCR if OCR added text layer containing secrets - redact hits text objects. If OCR would re-expose redacted zones incorrectly, OCR clean source then redact once. Test search on output PDF for redacted SSN digits.
Can recipients remove JoyPDF redaction?
Proper redaction shouldn't allow recovery - unlike password protection which is reversible with password. Assume sophisticated attacker tries forensic recovery on poorly redacted files - verification prevents embarrassment. Keep non-redacted original under strict access.
