Redact PDF – PDF Redaction Studio

Redact PDF files on Linux with AI. PDF Redaction Studio finds names, addresses, emails, phone numbers, SSNs, passport and ID numbers, bank details and faces, lets you review every suggestion, and permanently removes them from the PDF.

Redact your first PDF without an account. With a free account you get 100 pages per month.

Why PDF Redaction Studio

• True, permanent redaction — removes the hidden text and images under each box and cleans metadata, so redacted content cannot be copied or recovered. Many PDF editors only draw a black box on top.
• Local mode works offline — rendering, OCR, face detection and the redacted PDF are all done on your computer. Turn on Local mode and PII detection runs locally too.
• Built for Linux — native desktop app for Ubuntu and other distributions, with automatic updates through the Snap Store.

AI PII detection

• Detects 15+ types of sensitive data: names, ages, emails, phone numbers, addresses, zip codes, SSNs, passports, driver's licenses, credit cards, account numbers, IP addresses, URLs, organizations, dates and medical conditions
• Face detection finds photos on IDs, passports and HR files
• OCR redacts scanned PDFs and image-only documents
• Filter results by category or type, with a live count for each

Manual redaction tools

• Search & redact: find a word, case number or phrase and redact every occurrence at once
• Select text or draw a box over any area: images, tables, signatures
• Black or white redaction fill, 50-level undo/redo
• Preview the original, highlighted and redacted versions side by side before you export
