PDF redaction for law firms that actually destroys the text
Two failure modes have burned firms repeatedly: black boxes drawn over text that's still selectable underneath, and confidential documents uploaded to third-party servers to do the redacting. This tool eliminates both.
Why black rectangles keep failing
In a PDF, drawing a black shape over text doesn't remove the text — it sits in the file underneath, one copy-paste away. Court filings redacted this way have been unredacted by journalists and opposing counsel with nothing more than select-all. Proper redaction must rewrite the document so the content ceases to exist. PDFAirlock rebuilds redacted pages from pixels: after processing, there is no text object left to extract on those pages.
The verification report
After every redaction, the tool re-opens the output and audits it: zero extractable text on redacted pages, your search terms absent from the file's bytes, document metadata (author, title, revision info) stripped. If a searched name still appears on a page you didn't redact, the report tells you which page — before the document leaves your office. It's the answer to “are you sure it's really gone?” that you can screenshot into the file.
Privilege-compatible by architecture
Nothing is uploaded, ever — the processing happens in the browser on the machine the document already sits on. There is no vendor server holding privileged material, no processing agreement to review, no retention policy to audit. Load the page, disconnect from the internet, and redact: it works, which is the proof. How to verify this yourself →
