Why are accessible documents important?

To achieve an inclusive working world and information society, information needs to be consistently and reliably provided in a barrier-free form. This enables people with disabilities to have equal and independent access to all information.

In addition to accessibility being both an ethical and legal requirement, accessible documents offer further advantages:

  • Use in the mobile web: Ideal for displaying even on small screens such as smartphones.
  • Google loves them: The rich semantics of content leads to better indexing by search engines.
  • Future-proof: Accessible content is prepared for intelligent reuse (rich data, AI, other evaluations, conversion to other formats).
