Enhance PDF Accessibility with Automated Tagging

Add Tags to PDF

What is a Tagged PDF?

A significant part of making PDF accessible is ensuring the document is tagged. A tagged PDF is a document that includes an underlying tag tree that defines the structure of the whole PDF document. PDF tags give the ability to identify content as headings, lists, tables, etc., and to include alternate descriptions for images.

PDFix’s Auto-Tag API

Our automatic tagging is a powerful feature of our SDK. It significantly improves the quality of untagged PDF files whether you need to follow accessibility standards, publish PDFs on the web, or access structural data in your files.

PDFix features an advanced layout recognition engine that automatically identifies and tags document elements, including text, images, tables, and lists. This AI-powered auto-tagging ensures an accurate reading order and a logical document structure, making PDFs fully accessible and compliant with standards like PDF/UA and WCAG.
