Tagged and Accessible PDF with LaTeX – revisited

The talk was recorded and will become available on the PDFA website soon.

The slides of the presentation are available here. The audio renderings presented as as part of the talk are the untagged math formulas and later on the tagged math formulas for comparison.


Overcoming the sentiment that PDFs are evil (at least for accessible math)

This poster shows an end-to-end workflow for truly accessible PDFs containing math and other complex material. It also discusses the general challenges when trying to produce accessible STEM documents and explains why the PDF/UA-1 standard (in contrast to the PDF/UA-2 standard) is not suitable for documents containing mathematics.



News from the LaTeX Tagged PDF project: 2025



ACM Symposium on Document Engineering 2025 (DocEng 2025) Nottingham, UK

MathML and other XML Technologies for Accessible PDF from LaTeX

This short paper was presented at the ACM Symposium for Document Engineering (DocEng 2025); the official version is available in the ACM Digital Library. While LaTeX is capable of producing a PDF/UA-2 compliant documents, this is not necessarily the case when special journal classes are required by the publisher. The acmart class needed for DocEng proceeding supports tagging, but has some problems tagging the title correctly which is why the document, though tagged and fairly accessible, is not PDF/UA-2 compliant.

Slides of the talk are also available. These are tagged, generated using the new ltx-talk LaTeX class.




ACM Symposium on Document Engineering 2024 (DocEng 2024) San Jose, USA

Automatically producing accessible and reusable PDFs with LaTeX

This application note was presented at the ACM Symposium for Document Engineering (DocEng 2024); the official version is available in the ACM Digital Library, for direct access see below. While, as described in the paper, it is now possible to automatically generate accessible and PDF/UA-2 compliant documents with LaTeX, this is not necessarily the case when special journal classes are required by the publisher. The acmart class needed for DocEng proceeding does not support tagging yet, which is one of the reasons why the ACM DL contains only an inaccessible PDF of the paper.

It may take some time to make the acmart class fully compatible with the tagging extensions in all situations, because the class supports various journals (all with different frontmatter requirement), which is an area that the project hasn’t yet fully addressed.

However, for the current article (which is fairly simple from a strutural point of view) only a few modifications to the class were necessary to make it work. Thus, the version of the paper available from this site here is compliant with PDF/UA-2 and the Well-Tagged PDF (WTPDF-1.0) standard.

It has been produced using lualatex-dev (instead of pdflatex) and a patched version of the class to support tagging as far as necessary for this article. Other than that, no modifications to the LaTeX source were made.

The official version (untagged) in the ACM Library is the following:

LaTeX Tagged PDF — A blueprint for a large project


LaTeX Tagged PDF Feasibility Evaluation Study

This forty-page document contains information about a multi-year project, started by the LaTeX Project Team in 2020, that will extend LaTeX to produce tagged, and hence accessible, PDF with minimal manual intervention. It explains in detail both the project goals and the tasks that need to be undertaken, concluding with a detailed project plan. It is our blueprint for how we think the project should be undertaken.

The Introduction contains an overview of the benefits of the project and explains why LaTeX documents make a good starting point for the production of tagged PDF. More information about this blueprint and the project can be found in the article “LaTeX Tagged PDF — A blueprint for a large project” TUGboat, Volume 41-3 (2020), which will appear shortly.

The original version of this study dates from late 2019 and was addressed primarily to an audience within Adobe which consisted of engineers and managers with a wide knowledge of digital typography and electronic publishing but not necessarily much background within the specialized world of TeX, LaTeX and friends. This version of the study was updated in September 2020 with some minor redactions, corrections and clarifications.



TUG Conference 2020 (Online conference)

Quo vadis LaTeX(3) Team — A look back and at the upcoming years

The talk touches briefly on the questions “where we are coming from” (we being the LaTeX Project Team), “where we are now” and then focusses on the LaTeX Project’s plans for the upcoming years, which will primarily be focussed on providing an out-of-the box solution for generating tagged PDF with LaTeX and will include gentle refactoring of parts of the core LaTeX and providing important functionality, such as extended standard support for color, hyperlinks etc., as part of the kernel.

This is a multi-year journey that we have just started and we will briefly explain the places this will take us through. At its end we expect that LaTeX users are able to produce tagged and “accessible” PDF without the need to post-process the result of their LaTeX run.

A video of the presentation given by Frank is available on the TUG YouTube channel.
