Auto-redact PII
Detect SSNs, emails, phones, and cards — then permanently black them out on matched pages.
Privacy scanner
Scan a PDF for PII patterns and report what was found, without removing it.
Fingerprint
Generate a SHA-256 fingerprint of the file bytes and extracted text.
Remove metadata
Clear common Info fields (title, author, subject, keywords, dates). Does not scrub every hidden stream.
Encrypt PDF
Password-protect a PDF so it cannot be opened without the password.
Unlock PDF
Remove password protection from a PDF you own. Password stays on your device.
Confidential Send
Private prep in one pass — scan/redact PII, strip metadata, watermark, encrypt — or Email Ready. Batch many PDFs into a zip.
