LaTeX PDF Accessibility Notes

Tagging LaTeX PDFs and making them meet new accesibility standards was hard to say the least (Article about difficulties). The 2025 LiveTex update that added the capabilities was a long time coming, after the work of many people trying to make packages to do so and realizing the issues were with fundamental parts of LaTeX. Here are some quick links about making PDFs accessible as of May 2026.

• Full WCAG 2.1 Standards
• The LaTeX Tagging Project Homepage, TUG homepage
• The easiest way to add tags is in LaTeX with DocumentMetaData. This doesn't work with every package, but only requires a few lines of code: see From the LaTeX Project, Overleaf's Guide, , List of Current Compatible Packages
• Before the 2025 update, several authors ran packages with the goal of tagging. Most haven't been updated recently, as several authors shifted to the full project above. However, the packages still exist: accessibility, axessibility (also check out tagpdf)
• The foolproof way that requires a bit more learning is to convert LaTeX to HTML and add tags there: LaTeXML (quick reference to the manual), Tex4ht (and a secondary, step-by-step guide on the subject), Lwarp package
