PDF Tag Tree Field Guide

The PDF Tag Tree Field Guide is a free, practical reference that helps PDF creators and remediators understand common tag structures and apply them when building or reviewing accessible PDFs.

It covers the tag patterns used for headings, paragraphs, lists, tables, figures, links, notes, and form fields,  explaining what each tag does, what the target structure should look like, what commonly goes wrong, why the issue matters, and how to fix it. The guide focuses on PDF/UA compliance while supporting many WCAG requirements, and emphasizes a complete review process that includes checking reading order, verifying alt text, conducting manual reviews, using PAC to identify technical issues, and testing key elements with assistive technology.

Fittingly, the guide reinforces the principle it teaches: a technically complete tag tree is not enough on its own. Accessible PDFs must have a logical structure that matches the content and provides a clear experience for people using screen readers and other assistive technologies.
