PDF and accessibility
Can documents retain these advantages of 
layout, portability, security and still be 
accessible?
PDF documents support a logical, accessibles 
tructurethat is independant of the layout
Security used to cause an accessibility issue, not any 
more. Documents canbe securedagainst editing but 
still be accessible
Accessible PDFs can be produced quickly but, as with 
HTML, the source document must contain structure 
and semantics

When is PDF not accessible?
•
A scanned image is still an image, with no 
information for screen readers unless the 
information is added
•
Same for PDF, HTML or any document format
•
PDF can support a wide array of accessibility 
information for all content elements, but 
these must be added, in the source document 
or in Acrobat

Background of PDF Accessibility
Until 2001, PDF was not accessible:
Content not readable by AT
Each page was basically a flat image: 
▪ Scanned paper document
▪ Converted to image from source document 
Since then: PDF can (and should) be fully accessible
Accessible tag structure
Real text rather than image of text
Control over reading order
Text alternatives
Accessible form controls
PDF Accessibility: Tags
 A tagged document contains an underlying ‘tag tree’: 
 Represents the structure of your document
 Perceived by screen reader as document content
▪ Not tagged = not announced by AT
 Similar to tags in HTML
 Can be edited using the ‘Tags Panel’
 Always required for accessibility
 Enables typical screen reader 
features, such as:
▪ Heading navigation
▪ Table navigation
▪ Link lists
