WCAG 2.2 Compliance
WCAG 2.2 (Web Content Accessibility Guidelines) applies to PDFs to make them usable for everyone. The main principles are:
- • Perceivable: Users can sense the information (e.g., through sight or hearing).
- • Operable: Users can navigate and interact with the PDF.
- • Understandable: Users can comprehend the content and how to use it.
- • Robust: The PDF works with various technologies, including assistive ones.
- • Text Alternatives: Provide descriptions for images and non-text content.
- • Keyboard Navigation: Ensure everything can be done using only a keyboard.
- • Logical Structure: Organize content with proper headings and tags for screen readers.
- • Sufficient Contrast: Make sure text and interactive elements have enough color difference.
- • Clear Links: Use descriptive text for links.
- • Accessible Forms: Label form fields clearly and make them easy to use.
- • Captions/Transcripts: Include these for videos and audio.
- • Avoid Flashing: Don't use content that flashes rapidly.
- • Consistent Help: If help is provided, keep it consistent.
- • Target Size: Make interactive elements large enough to easily select.
- • Focus Visibility: Ensure keyboard focus is always clearly visible.
Short Guidelines for Accessible PDFs:
By following these guidelines, you can create PDFs that are more accessible to a wider audience. Aiming for WCAG 2.2 Level AA is generally recommended.
