PDF accessibility

We will make your PDFs accessible to the highest possible standards. We have an unrivalled depth of knowledge and experience in the field, and are the UK’s longest-established provider of PDF accessibility services.

Testing and benchmarking

Our quality control procedures are second to none. We benchmark against WCAG 2.1, and PDF/UA (when appropriate). As standard, we also test with a range of assistive technologies, each of which can inform the way a PDF should be tagged or otherwise edited for accessibility. Our test set up includes: 

  • Screen readers: JAWS (versions 9 to 2018), SuperNova, NVDA 
  • Screen magnifiers: ZoomText (versions 9, 10 and 11), SuperNova, MAGic 
  • Literacy software solutions: Read&Write Gold, Claro Read, vBookz PDF Voice Reader
  • Speech recognition: Dragon Naturally Speaking

PDF accessibility testing/audits

We can test your PDFs for accessibility against WCAG 2.1 and PDF/UA, and with a range of assistive technologies, as appropriate. We will then provide you with a detailed report on any problems they may contain and how to fix them.
