Remove Sensitive Information from PDFs

AI-powered detection finds SSNs, names, addresses, and other PII you might miss. True redaction permanently destroys the underlying text — not just a black box on top.

Black boxes aren't redaction

Drawing a black rectangle in a PDF editor leaves the text underneath — selectable, searchable, and extractable by anyone with basic tools. True redaction permanently removes the data from the file.

Zero-Knowledge Architecture

Your sensitive documents never leave your browser. Processing happens entirely on your device.

100% Browser-Based

All PDF processing happens locally using WebAssembly. Your files never touch our servers — or anyone else's.

No Upload Required

Unlike Adobe or Smallpdf, we don't upload your documents to process them. Zero network transmission.

AI Stays Local

PII detection runs client-side. The only external call is to confirm your Pro status — never your document content.
