Export an accessible PDF

Create a tagged PDF and use CorTeX's report to check its language, structure, tables, and figures.

CorTeX attempts a tagged PDF/UA-2 export and reports what the generated file actually contains. Check that report rather than assuming every class or document meets PDF/UA requirements.

Prepare the source#

1. Compile the document once and open the PDF preview.
2. Give each meaningful figure an alternative description, for example \includegraphics[alt={A plot showing the measured trend}]{figure.pdf}.
3. Choose Download accessible PDF.
4. Review the language, tags, headings, tables, figures, and class-support results. Fix the source and export again as needed.

You do not need to change the project's TeX Live snapshot. Accessible export runs a separate full compile on the latest tested TeX Live 2026 profile and leaves the ordinary preview unchanged.

Check class support#

• Supported at the current tagging-kernel baseline: article, report, book, KOMA-Script, and amsart.
• Partially supported: llncs, IEEEtran, and elsarticle.
• Not supported: memoir, acmart, revtex4-2, and beamer.
• Unknown classes: CorTeX attempts the export and reports the result without promising conformance.

The generated document can still have verification gaps, including known baseline gaps from the LaTeX tagging kernel. See LaTeX compilation for the ordinary preview workflow.
