Secure PDF
Encrypt, decrypt, and secure PDF files
Encrypt PDF
Encrypt a PDF with a password using AES-256. Set separate open and permissions passwords, all handled in your browser.
Sanitize PDF
Remove metadata, JavaScript, embedded files and annotations from a PDF in one pass, so nothing hidden travels with the document.
Find and Redact
Search a PDF for text or a pattern and redact every match across all pages. Content is removed, not just covered with a black box.
Unlock PDF
Remove password protection from a PDF you have the password for, so you can open and edit it without entering the password each time.
Flatten PDF
Flatten PDF form fields and annotations into the page so the values cannot be changed and display correctly in every viewer.
Remove Metadata
Strip the author, title, dates, keywords and producer information from a PDF, so no identifying details travel with the file.
Change Permissions
Set what a PDF allows: printing, copying text, editing and annotating. Control document permissions without requiring an open password.
Digital Signature
Apply a cryptographic digital signature to a PDF using an X.509 certificate in PFX, P12 or PEM format, with a visible signature and timestamp.
Validate Signature
Check the digital signatures on a PDF - signer identity, certificate details, validity dates and whether the document has been altered since signing.
