The freeware program PAC provides a fast way to test the accessibility of PDF files. PAC supports both experts as well as end users conducting accessibility evaluations.
This newest version features greatly improoved program stability. It also contains fixes to many bugs which used to make the application crash unexpectedly.
The PDF checking process has been further improoved so that PAC can support you even better in creating accessible documents.Click here for an overview of the most important changes.
PAC ist recommended from World Wide Web Consortium (W3C): PDF Techniques for WCAG 2.0
Test criteria
PAC conducts tests on these 14 criteria within PDF documents:
- Document is marked as tagged
- Document Title available
- Document Language defined
- Accessible Security Settings
- Tab follows Tag-Structure
- Consistent Heading Structure
- Bookmarks available
- Accessible Font Encodings
- Content completely tagged
- Logical Reading Order
- Alternative Text available
- Correct Syntax of Tags / Rolls
- Sufficient contrast for Text
- Spaces existent
Preview
PAC offers you the aded possibility of displaying a preview of the structured PDF document in a web browser. This preview shows which tags are included in the PDF document and presents the accessible elements in the same way as they would be interpreted by assistive technologies (such as screen readers).
As a new working tool, it is now possible to display the original PDF view side-by-side with the PAC Preview Window (the PDF View will appear to the right of the Preview Window).
Report
In the PAC Test Report, every checkpoint, along with its status and corresponding detailed messages is being displayed. The included links make it possible to navigate within the test report. Clicking the linked error messages will open the tested document in your web browser and the most probable location of the error is shown.
