Secure PDF
Encrypt, decrypt, and secure PDF files
Timestamp PDF
Add a signature field recording your device clock time to a PDF. Not a trusted RFC 3161 timestamp: no timestamp authority is contacted.
Encrypt PDF
Password protect a PDF in your browser with 256-bit AES. Set an open password, an owner password and print or copy permissions. No upload needed.
Sanitize PDF
Remove JavaScript, attachments, links and metadata from a PDF, and optionally comments, in your browser. See what stays in the file before you share it.
Find and Redact
Search a PDF for names, numbers or patterns and cover every match with an opaque box in your browser. Rasterise afterwards to remove the hidden text.
Redact PDF
Draw black, white or red boxes over areas of a PDF and burn them into the pages in your browser. See what stays underneath before you share. No upload.
Decrypt PDF
Remove a password from a PDF you can already open: enter the current password and download an unlocked copy. Not a password cracker. No upload.
Flatten PDF
Flatten filled PDF form fields into fixed page content in your browser, so the answers can no longer be edited as a form. Comments are not flattened.
Remove Metadata
Clear the title, author, subject, keywords, creator and producer from a PDF in your browser. Dates and XMP data stay; details below. No upload.
Change Permissions
Choose whether readers may print, copy, edit, comment on or fill a PDF. Restrictions apply only with a new owner password; AES-256, in your browser.
Digital Signature
Sign a PDF with your own .p12, .pfx or .pem certificate in your browser. Adds an adbe.pkcs7.detached signature, optionally visible. No trusted timestamp.
PDF Signature Inspector
See who signed a PDF, the certificate issuer and dates, and whether data was added after signing. It does not verify the signature; use a full PDF reader.
Certificate Encrypt & Sign
Secure PDFs using asymmetric public-key certificate encryption, paired with a 3D gold wax-seal imprint and PKCS#7 signature.
Sensitive Data Redaction
Detect email addresses, phone numbers and ID patterns in a PDF and cover them with boxes in your browser. Rasterise afterwards to remove hidden text.
Signature Position Guide
Automatically locate signature fields in contracts, and inject interactive hovering guides and anchors for quick signing.
