What we find when we open real documents
The a11yfy technical blog. Every number here comes from a measurement we ran ourselves, on real files, in a way you can check. We show what the accessibility standards actually require, where people most often trip up, and what good practice looks like. PDF-focused, but not only about PDFs.

We validated real-world PDFs against PDF/UA-1. One tool destroyed compliance in a single pass.
What the official PDF/UA validator finds in public-sector PDFs — and the reproducible experiment showing how a routine optimisation step silently strips accessibility out of a compliant file.
