Accessible PDFs Start in InDesign
The earlier accessibility issues are identified, the easier they are to fix.
The Highlander Accessibility Checker helps you find and resolve accessibility issues before export, saving time, reducing rework and supporting the creation of more accessible PDF documents.
Why Use the Highlander Accessibility Checker?
Most accessibility problems originate in the InDesign document itself.
A common workflow is:
- Create the document in InDesign
- Export to PDF
- Run accessibility checks
- Discover issues
- Return to InDesign
- Fix the document
- Export again & repeat the process
The Highlander Accessibility Checker helps move much of this process earlier in the workflow by identifying accessibility issues before export. This means fewer surprises, less rework and a more efficient route to creating accessible PDFs.

Frequently Asked Questions
What is Highlander Accessibility Checker for InDesign?
Highlander Accessibility Checker is an Adobe InDesign plugin that checks InDesign documents for common PDF accessibility issues before they are exported to PDF.
Does it replace Acrobat or PAC?
No. The plugin checks the InDesign source document before export. Acrobat, PAC and other PDF accessibility tools are still needed to check the final exported PDF. It does however significantly reduce the number of issues that make it into the PDF document in the first place.
Can it guarantee PDF/UA compliance?
No automated pre-export checker can guarantee PDF/UA compliance on its own. The plugin helps identify source-document issues that can affect PDF/UA readiness and accessible PDF production.
What does the plugin check?
It checks issues such as document titles, language settings, heading hierarchy, export tags, Articles panel setup, reading order indicators, missing alt text, decorative image settings, table structure, list formatting, links, forms and placed PDFs.
Who is it designed for?
It is designed for InDesign users, designers, communications teams, councils, universities, charities, NHS organisations and other organisations that need to create more accessible PDFs.
Does it check the final PDF?
No. It checks the InDesign document before export. The exported PDF should still be checked using Acrobat, PAC or another PDF accessibility checker.
Does it help reduce PDF remediation work?
Yes. By identifying many accessibility issues before export, it can reduce the number of problems that need to be fixed later in Acrobat or another PDF remediation tool.
