Enterprise Extension

PDF Forms Filler Enterprise Extension is an add-on for PDF Forms Filler for CF7, replacing the Pdf.Ninja API with local binaries for reading and generating PDF files directly on the server where it’s installed.

What is the Enterprise Extension?

The Enterprise Extension is a premium add-on for PDF Forms Filler for CF7 which replaces the use of the Pdf.Ninja API with local binaries. It allows reading and generating PDF files directly on the server where the plugin is installed.

This extension is particularly valuable for organizations that:

  • Handle sensitive or confidential information
  • Need to comply with strict data privacy regulations
  • Require high-volume PDF processing
  • Want to eliminate API usage limitations

Note: The Enterprise Extension currently DOES NOT integrate with PDF Forms Filler for WPForms or PDF Forms Filler for WooCommerce. Support will be added in the future.

Key Features

Local PDF Processing

The Enterprise Extension processes all PDF operations locally on your web server:
