What is the difference between WCAG, BITV, BFSG, and EAA?

WCAG is the technical standard. EN 301 549 and BITV 2.0 translate it into European and German requirements. The EAA and BFSG define who is required to provide accessibility.
The WCAG (Web Content Accessibility Guidelines) are the technical standard for accessible web content. EN 301 549 and the German BITV 2.0 translate it into European and German requirements, respectively. The EAA (European Accessibility Act) and its German implementation, the BFSG (Barrierefreiheitsstärkungsgesetz), define who is required to provide accessibility – since June 2025, this includes many companies.
