Ce que nous trouvons en ouvrant de vrais documents
Le blog technique d'a11yfy. Derrière chaque chiffre, une mesure que nous avons réalisée nous-mêmes, sur de vrais fichiers, vérifiable. Nous montrons ce que les normes d'accessibilité exigent réellement, les pièges les plus fréquents et les bonnes pratiques. Centré sur le PDF, mais pas uniquement.

PowerPoint's accessibility checker asks whether your slide has a title. Excel's doesn't ask that at all.
Microsoft runs a different rule set in every Office app. We mapped exactly what PowerPoint and Excel check that Word doesn't — and measured what Hungarian public bodies actually publish from each. Real Excel exports had table structure nobody checks; PowerPoint barely appeared at all.

Alt text best practice says every image needs a description. We opened 540 real ones to see what's there.
Alt text is the accessibility rule everyone's heard of. We walked the structure tree of 111 real public-sector PDFs and read every /Alt value on every figure — 540 of them — to see how many actually describe anything.

A PDF form you can't fill in isn't an inconvenience. It's an application you can't submit.
We went looking for real, fillable PDF forms in public-sector documents and found four. We ran them through veraPDF: the best-labelled one still failed on every single field. What /TU gives a screen reader that /T never will.

How to make a PDF accessible: the honest workflow
Most guides for making a PDF accessible assume every step goes right. This one prices each step — what a machine can do, what needs a person, and, computed from 59 real validated documents, the actual split between them.

Embed fonts in your PDF. It isn't a printing setting — it's an accessibility one.
64% of the Word-exported public-sector PDFs we validated ship with fonts not embedded — the most common PDF/UA failure that has an actual one-click fix. What a missing font does to a screen reader, and where in Word to fix it for good.

Your Word accessibility check passes. The PDF still fails. Here's why.
Word's Accessibility Checker has seven rules. PDF/UA has thirty-one checkpoints. We validated 59 Word-exported public-sector PDFs to see exactly where the gap falls — and it falls in the same three places nearly every time.
