Signatures Showcase

With the ability to sign PDFs with both Electronic Signatures and Digital Signatures we have your digital transactions covered. E-signature is an alternative to a traditional signature, written by the human hand. Digital signature is very secure and less risky because it’s authorized and regulated by certification authorities. Time stamping guarantees the long-term preservation of digital signatures.


Redaction permanently removes sensitive content from the selected area. Once the text or graphics are removed, they cannot be retrieved. The redacted area can be filled with custom content like redaction text or color. PDFix also automatically removes all private information, and personal data connected to the redacted area.

With PDFix API you can search for custom text patterns using regular expressions and automate your redaction workflows.
