Security & privacy
Control who can open, print, or extract from a PDF, and check documents for hidden risk — passwords, permissions, personal data, and unique fingerprints.
6 free, browser-based Security & privacy tools.
Encrypt PDF
Password protect a PDF free, entirely in your browser — set a password to open the file, optionally an owner password and print, copy or edit limits, and it is encrypted with AES-256.
Remove Password
Remove the password from a PDF you can already open, free and entirely in your browser — type the password you know, confirm you are allowed to, and download an unprotected copy.
Unlock PDF Permissions
Remove print, copy and edit restrictions from a PDF that opens without a password, free and entirely in your browser.
Auto-Redact PII
Auto-redact personal information in a PDF free, entirely in your browser — the tool scans for names, emails, phone numbers, and similar PII and blacks it out for you.
Privacy Risk Scanner
Scan a PDF for privacy risks free, entirely in your browser — the tool flags hidden metadata, embedded personal information, and tracking artifacts before you share the file.
PDF Fingerprint
Generate a PDF fingerprint free, entirely in your browser — compute a cryptographic hash of the document's content to verify it hasn't changed later.
