Inaccessible
Typically an image-only PDF where the document is scanned and saved as a PDF.
- Example 1 - Yeats: A scanned document
- Example 2 - A World of Love: Appears to be accessible but you are unable to select or copy the text, thus it is also an image PDF.
Partially Accessible (Untagged)
Document has been created by using the print to PDF option; the Adobe Printer; or a non-Adobe PDF converter.
- Example 1 - Letter: Simple, one column text documents are typically usable with this level of accessibility.
Accessible
Tags are implemented to identify sections of document, reading order, images, etc. The document is accessible for assistive technologies, smartphones, e-readers, and mobile devices.
- Example 1 - Brochure for an online course: This document is tagged to ensure it can be read correctly when the text is re-ordered (see Verify Accessibility of PDF).
- Example 2 - Adobe PDF Manual: Bookmarks have been implemented to allow for easy navigation.
