Free & Fast — No server uploads, no installs, no watermarks.
Select a PDF, draw black boxes to hide any private content, and export a flattened redacted PDF. Everything happens in your browser—nothing is uploaded.
⚠️ Warning: Redactions are permanently burned into the page images and the original text is destroyed—hidden information is not recoverable from the output.
This is secure for most use cases, but not a certified legal/compliant redaction method. For sensitive legal, medical, or compliance documents, use a professional redaction tool.
This free online PDF redactor lets you permanently remove sensitive information from any PDF document directly in your browser. Draw black boxes over confidential text, personal data, or sensitive images to create a securely redacted PDF. Perfect for removing social security numbers, financial information, addresses, or any private content before sharing documents.
Our browser-based PDF redaction tool ensures complete privacy - your documents never leave your device. The redacted areas are permanently burned into the PDF as black boxes, making the original text completely unrecoverable. Export your redacted PDF instantly with no watermarks, registration, or software installation required.
Compliance Notice: This redaction method converts pages to images and removes all underlying text and metadata. While this provides strong security for most business and personal use cases, it may not meet specific government, legal, or regulatory compliance standards. For certified legal redaction or HIPAA compliance, consult a professional redaction solution.
This PDF redaction tool is designed for legitimate privacy protection and document sharing purposes. Please use this tool responsibly and in compliance with all applicable laws.
Appropriate uses include:
Important restrictions:
Users are solely responsible for ensuring their use of this tool complies with applicable laws, regulations, and legal obligations. This tool does not provide legal advice - consult with appropriate professionals for compliance guidance.
Does this really hide the original text?
Yes, the original PDF text/content is destroyed and unrecoverable by normal means.
Can I undo a black box?
Yes! Use Undo on each page. Clear erases all redactions for that page.
Is this legal for sensitive/government docs?
For most users, yes, but it is not certified legal/compliant. See the warning above.
Can I redact multiple pages at once?
You'll need to redact each page individually by drawing boxes on each one, but you can download all pages together as a single redacted PDF.
Does this work offline?
Once the page loads, yes! Everything runs in your browser, so you can redact PDFs even without an internet connection.
Will this work on large PDF files?
Yes, but very large files (50+ MB) may take longer to process and use more memory. For best performance, consider splitting very large documents first.
