LaTeX Beamer Accessibility Checker

Free · Online · WCAG 2.1 AA / ADA Title II readiness · No signup

Can your lecture slides be made accessible? Upload a LaTeX Beamer deck, or its compiled PDF, and get a free, honest readiness score: whether the slide class supports tagging, what blocks it, and the realistic path to accessible slides. Beamer does not yet produce tagged PDFs, and we tell you straight, along with what to do about it.

What this Beamer accessibility checker looks at

Tagging support Whether the slide class can produce a tagged PDF at all. Beamer is not yet tagging-aware, so its PDFs read as unstructured text to a screen reader, however clear they look on screen.
Critical
Alt text & language Whether images on your slides carry alternative text and a document language is declared, so a screen reader can announce them.
Per image
Structure & reading order Whether frame titles, headings, and lists are real structure a screen reader can navigate, rather than visual styling that only looks like structure.
Structure
Math on slides When slides carry equations, whether the math is exposed as MathML rather than flattened to an image with no alternative.
STEM
Runs on your Beamer source (.tex/.zip) or the compiled .pdf. Your file is analysed and discarded immediately; only the report is kept, briefly.

The rules it maps to

WCAG 2.1 Level AA The technical standard for accessible documents, including the presentation PDFs you share with students.
The standard
ADA Title II The 2024 DOJ rule adopts WCAG 2.1 AA for US public universities, and course materials are in scope. Larger entities comply by April 2026, smaller ones by April 2027.
Apr 2026 / 2027
Tagged slides (ltx-talk) Tagged, accessible slides in LaTeX today generally mean moving from Beamer to the tagging-aware ltx-talk class. The report tells you how far your deck is from that.
The path
This tool checks your deck against these standards. It does not determine your legal obligations.

What still needs a human

The migration itself Software can tell you Beamer blocks tagging; converting a deck to an accessible class while keeping the look and animations is human work.
Human
Screen-reader test How the finished slides actually sound, and whether they read in a sensible order, can only be confirmed by testing with a real screen reader.
Human
The report is an honest readiness assessment, not a certification: it flags what software can verify and is honest about what it cannot.

Accessible lecture slides from LaTeX Beamer: your real options

If you have been told your course slides must meet accessibility requirements and your decks are in Beamer, here is the honest decision, without the runaround.

Start from the honest fact: Beamer cannot do it

Beamer predates PDF tagging and is on the no-support list of the LaTeX tagging project: there is no package to load or option to pass that makes a Beamer deck produce a tagged PDF. Any plan that begins "keep the deck exactly as it is and make it accessible" is not a real plan. Your options all involve either a different class or a second format.

Option 1: migrate the deck to ltx-talk

ltx-talk is a presentation class built tagging-first, with deliberately Beamer-like syntax: frames stay frames, and straightforward decks (title, bullets, figures, math) port quickly, often minutes per lecture. Decks that lean on heavy overlays, custom themes, or TikZ animations are real migration work. This is the right option when the deck itself must be the accessible artifact going forward.

Option 2: publish an accessible companion

Keep the Beamer deck for the projector and publish the same content as an accessible document: the source is already LaTeX, so a tagged article-class handout (or an HTML version) is usually a modest edit, not a rewrite. For a back catalog of decks this is often the pragmatic route, and lecture notes are frequently more useful to students than slides anyway. The requirement is equal access to the content, and a genuinely accessible companion provides it.

What does not work

Three common dead ends. Re-saving or printing the PDF through another tool does not add tags; it usually strips what little structure exists. Rebuilding the deck in PowerPoint trades your math quality away and still leaves you doing accessibility work by hand. And automated "make my PDF accessible" fixers cannot invent the structure Beamer never wrote. Checking the deck here first tells you how far you actually are, before you spend effort in the wrong direction.
