What the PDFix Marketplace Does
The PDFix Actions Marketplace is a growing library of AI-driven accessibility tools that integrate directly into PDFix Desktop or PDFix SDK. Each action automates a specific remediation task – from auto-tagging document structure to generating MathML for mathematical formulas – reducing hours of manual work to a single click.
Every action is labeled so you know exactly what you’re getting:
🖥️ Local: Runs entirely on your machine. No data leaves your environment. Ideal for sensitive or regulated documents.
☁️ Cloud: Connects to an external AI model via encrypted connection for higher accuracy or large-scale processing.
🆓 Free: No license or payment required.
💰 Paid: Billed through the provider directly. Each paid action lists its own licensing terms.

Frequently Asked Questions
Which accessibility standards do the actions support?
PDFix actions are designed to meet PDF/UA (ISO 14289-1), WCAG 2.1 and 2.2, and Section 508. Individual action pages specify which checkpoints each addresses.
Are the actions free to use?
Twelve of the sixteen actions in the marketplace are currently free, including auto-tagging with IBM Docling, OCR with Tesseract, formula MathML generation with Paddle, and alt text generation with Salesforce BLIP, and more.
Do I need Docker to use the marketplace actions?
All actions require Docker to run, except the Duplicate MCID Report, which is included directly in PDFix Desktop. See the guide How to add action & install Docker.
Can I run actions in batch?
Yes. All PDFix actions integrate with PDFix Desktop’s batch processing engine, allowing you to process hundreds of PDFs in a single automated run.
Is my document data sent to third parties?
Local actions process everything on your system with no external calls. Cloud actions connect to third-party AI providers (OpenAI, Amazon Textract, etc.) via encrypted connections. Check each action’s data handling section before use with sensitive documents.
Disclaimer: PDFix provides tools and technology to assist in making your documents accessible, but we do not guarantee 100% accessibility. Achieving full compliance requires human checks and intervention, as no tool can ensure complete accessibility. Please note that PDFix is a technology provider, not a service provider. The responsibility for document compliance rests with the user.
