Redact PDF Files Instantly
Remove sensitive information from any PDF document in seconds. AI-Redact uses advanced machine learning to automatically detect and permanently erase names, addresses, financial data, and other PII — so you never accidentally share private information.
The Problem with Manual PDF Redaction
- Manually drawing black boxes over PDF text is tedious and error-prone — you can easily miss a name, date, or account number buried on page 15.
- Most PDF editors only hide text visually. The underlying data remains embedded in the file and can be copied, searched, or extracted by anyone with basic tools.
- Free online PDF tools often upload your sensitive documents to unknown servers with no guarantee of privacy or deletion.
- Adobe Acrobat Pro's redaction feature costs $22.99/month and still requires you to manually locate every piece of sensitive information yourself.
- Redacting PDFs by printing, blacking out with a marker, and re-scanning destroys text searchability and produces low-quality output.
How AI-Redact Solves This
- AI-Redact automatically scans every page and identifies sensitive information including names, addresses, phone numbers, SSNs, and financial data — so nothing gets missed.
- All redactions are permanent and irreversible. Redacted content is completely removed from the PDF, not just covered with an overlay.
- Your PDF is processed securely and never stored on our servers after processing is complete. No third party ever sees your document.
- The free tier lets you redact up to 4 pages per PDF with zero cost and no account creation. Pro users get unlimited pages and batch processing.
- Output PDFs retain their original quality, formatting, and text searchability — only the sensitive content is removed.

Capabilities
Everything You Need to Redact PDFs
Purpose-built for secure, thorough, and permanent PDF redaction — whether you need to redact one page or one thousand.
Permanent, Irreversible Redaction
Unlike simple black boxes or highlights, AI-Redact removes the underlying text data from the PDF entirely. Redacted content cannot be recovered, copied, or searched — ever.
All Text Types Detected
Automatically finds and flags names, email addresses, phone numbers, Social Security numbers, dates of birth, credit card numbers, bank account details, and custom patterns you define.
Metadata Cleanup
PDF metadata like author names, creation dates, software details, and embedded comments can leak sensitive information. AI-Redact strips document metadata alongside visible text redaction.
Batch Processing for Pro Users
Need to redact dozens or hundreds of PDFs? Pro tier supports bulk uploads with queue management, so you can process an entire folder of documents in one session.
Free Tier with No Signup
Redact any PDF up to 4 pages completely free — no email, no account, no credit card. Just upload, review, and download your redacted file immediately.
Fast Processing
Most single-page PDFs are processed in under 5 seconds. Multi-page documents typically complete in 10-30 seconds depending on content density, with real-time progress tracking.
