Adobe PDF Standards Guide

A PDF is only as good as its tags.

Creating for Accessibility

Accessibility starts before you even open Acrobat. The best way to create an accessible PDF is to start with a "born accessible" source document:

  • Source Conversion: Always use the "Save as PDF" or "Export" features in Microsoft Word or PowerPoint. Avoid "Printing to PDF," as this often strips out the tags and structural metadata required for WCAG SC 1.3.1 (Info and Relationships).
  • Scanned Documents (OCR): If you must use a scanned document, you must use the Recognize Text tool. Without Optical Character Recognition, a PDF is just a giant image, violating WCAG SC 1.1.1 (Non-text Content).

The Accessibility Setup Assistant

Acrobat Pro includes a specialized wizard to configure the environment for users of assistive technology:

  • Go to Menu > View > Read Out Loud > Activate.
  • Open All Tools > Prepare for Accessibility.
  • Select Setup Assistant to set high-contrast display options and configure how many pages the screen reader should process at once.

The Full Check Audit

Adobe's "Full Check" is the industry standard for PDF verification. It checks for 31 different accessibility criteria, grouped into categories:

Document-Level Checks

Ensures the document has a title, specified language, and is correctly tagged to satisfy WCAG SC 2.4.2 (Page Titled).

Page Content & Reading Order

Identifies if the reading order follows a logical path and if non-text elements have alt text, supporting WCAG SC 1.3.2 (Meaningful Sequence).

Tables, Lists, and Links

Verifies that data tables have headers and lists are correctly formatted. Note: The checker will often prompt for a "Manual Check" for reading order, as AI cannot always determine the intent of a complex layout.

Accessible PDF Forms

Interactive forms are the highest-risk elements in a PDF. To ensure compliance with WCAG SC 4.1.2 (Name, Role, Value), follow these steps:

  • Tooltips as Labels: In PDF forms, the "Tooltip" field in the form property dialog acts as the accessible name for screen readers. Never leave it blank.
  • Tab Order: Use the Fields pane to drag and drop fields into the correct sequential order.
  • Required Fields: Clearly mark required fields and ensure the state is programmatically set in Acrobat.
