What we do

You get an accessible PDF from us that has retained its original look. However, we will have added an invisible layer with instructions to serve people using assistive technologies in reading, understanding and navigating the PDF content on an equal footing with a common user.

Rich semantics

Appropriate tags are added to the content of the PDF and may include:

  • Headings
  • Paragraphs
  • Lists
  • Tables
  • Links
  • Figures
  • Captions
  • Notes
  • Form fields
  • Formulas
  • Quotations
  • Table of Contents

Correct reading order

The order of the tags, also known as the logical order, follows the natural reading order. You can see the logical order for example in the Screenreader Preview of the free PDF Accessibility Checker (PAC) 2.

Identification of artifacts

Decorative elements, repeated content in page headers and footers and other elements that are not relevant for understanding the document are marked as artifacts.

Navigation aid

Table of Content
