Secure PDF

Remove PDF restrictions. Unlock printing, copying, and editing permissions.

Password protect PDF files. Add encryption and set permissions.

Remove what a PDF carries besides its pages: properties and metadata, scripts, attached files and links that lead outside the document.

Search a PDF for words, numbers or patterns and black out the matches you select. Every page with a redaction is saved as an image.

Remove password from PDF files. Unlock password-protected documents.

Turn the form fields of a PDF into ordinary page content, so that they can no longer be filled in or changed. Comments and layers are left as they are.

Strip metadata from PDF files. Remove author, dates, and document properties.

Set what a PDF allows: printing, copying, editing, filling in forms. The limits need a new owner password; PDF readers honour them, but they are not a lock.

Sign a PDF with your own certificate file (.pfx, .p12 or .pem), in your browser. A PDF reader can then tell if the file was changed; whether it trusts the signer depends on your certificate.

Check the digital signatures in a PDF: whether the document changed after signing, who the certificate names as signer, and when.

See what a PDF carries besides its pages and take it out: document properties, XMP metadata, editing-program data and leftovers of earlier edits.

Find email addresses, phone numbers, ID numbers, bank card numbers and your own words in a PDF, look over what was found, and remove what you choose for good.
