How to make PDFs accessible
Document language
The document's language must be set correctly. It must be the same language as the document title and the document's contents.
To check a PDF's language using Adobe Acrobat, select 'File', then 'Properties'. Navigate to the 'Advanced' tab and review the language set in the 'Reading Options' section. The language for English language documents should be 'EN-GB' or 'English'.
If you need to change it, select the correct language from the drop-down menu in the language field. If the language is not in the drop-down menu, manually type in the correct ISO language code.
