Review steps
- Confirm whether the PDF contains a tag structure.
- Review tag hierarchy and attributes for the pages or content areas that matter most.
- Compare structure with the visible reading order in the preview.
- Treat missing, shallow, or confusing tags as a reason for a deeper accessibility review.
Details
Use the filter field to search tags. Select a tag to open Tag Info with available attributes and structure details. When bounding information is available and highlighting is enabled, selecting a tag highlights the corresponding content in the PDF preview.
Export
Accessibility can export tag data as CSV or JSON. Export requires PDF Auditor Pro.
