PDFTron's PDFSecure is a stand-alone command-line application that provides users with an efficient means of adding, removing, or changing security settings on existing PDF documents or whole directories of documents. PDFSecure can also be used to modify document information metadata and to web-optimize files through a process known as linearization.

Like other PDFTron products, PDFSecure does not rely on any other third-party software.

PDFSecure is also available as a library component of PDFNet SDK that can be used as a building block for other client and server-based applications. Please see http://www.pdftron.com/pdfnet for more information.

linkWhy PDFSecure?

  • Encryption. PDFSecure supports industry standard PDF security (RC4 and AES).

  • Efficiency. PDFSecure is based on PDFNet, making it extremely fast and efficient.

  • Support for very large documents.

  • Built-in support for multi-threading makes PDFSecure a good match for multi-threaded, server-based applications.

  • Support for all PDF formats (PDF 1.0 to ISO32000) and Acrobat documents.

linkKey Functions

  • Encrypt any PDF document using AES (Advanced Encryption Standard) encryption and Crypt filters.

  • Encrypt any document using standard PDF 40 and 128 RC4 bit encryption.

  • Modify security settings (for example, change passwords or security permissions).

  • Completely remove security from existing documents.

  • Set of modify document information metadata such as Author, Subject, Title, Keywords, etc.

  • Linearize and optimize existing PDF documents for 'Fast Web View' capability and faster downloading.

  • Files with broken cross reference tables are automatically repaired.

  • Configuration file for frequently used options.

  • Supports automation and batch processing.

linkCommon Use Case Scenarios

  • Server-based, on-demand encryption and decryption of PDF documents based on specific security requirements.

  • Batch processing of PDF collections that require uniform security and permission settings across many documents. PDFSecure is particularly useful in assembling product catalogues, brochures, and forms.

  • Linearization of existing PDF documents for 'Fast Web View' capability.

linkOperating Systems Supported

  • Windows, Linux and Mac.
