Quick Answer
PDF redaction removes sensitive information from documents. This tool draws redaction boxes on each page, then rebuilds every page as an image with those areas burned out, so redacted text cannot be copied, searched, or extracted from the exported file. Metadata is scrubbed on export. To redact a PDF: draw boxes over sensitive info (SSN, addresses, names), apply redaction, and download the rebuilt file.

Frequently Asked Questions
How does this tool redact a PDF?
When you apply redactions, each page is re-rendered as a high-resolution image with the redacted areas painted out, and the PDF is rebuilt from those images. Because the output contains images rather than the original text objects, the text under a redaction does not exist in the exported file — copying, searching, or text extraction returns nothing for redacted areas.
Is redacted information truly gone?
Yes. The exported document is rebuilt from page images — the original text objects, hidden layers, and metadata are not carried over, and document metadata is scrubbed on export. Keep your original file separate if you need it; the redacted copy is the safe one to share.
Is my document secure during redaction?
Absolutely. All processing happens locally in your browser. Your PDF is never uploaded to any server, ensuring complete security for sensitive documents.
Can I redact multiple areas at once?
Yes — draw as many redaction boxes as you need, across any pages, then apply them all in one export. Double-click a box to remove it before applying.
What types of information should I redact?
Common items to redact include: Social Security numbers, addresses, phone numbers, financial account numbers, medical information, signatures, and any other personally identifiable information (PII).
