Redact a PDF
AI finds SSNs, addresses, phone numbers, and other PII. You pick which categories to redact. AttachKit draws opaque rectangles and strips PDF metadata.
The text content of your PDF is sent to a third-party AI provider for PII detection. PDF bytes never leave your browser.
No PDF handy?
True redaction, in your browser
Black out sensitive text in a PDF — and actually remove it, not just cover it — all on your device, with no upload.
Nothing is uploaded
The whole thing runs in your browser — open your network tab and watch: your file never leaves your device. Most online tools round-trip your document through their servers.
Removed, not hidden
AttachKit deletes the underlying text and rebuilds the page, so redacted content can't be copied, searched or recovered — unlike a black box drawn on top.
Optional AI PII detection
Let on-request AI find names, SSNs, emails and more to redact (opt-in) — and even then only the page's extracted text is sent to flag them, never your PDF file, and the blackout itself is applied in your browser.
