Issue
The PDF format was created to preserve formatting in print documents. PDFs created from scanned or inaccessible documents are nothing more than full-page pictures of text. They need to be “tagged” in order to make them accessible.
How to check
- Try to click and drag your cursor over the PDF. If no text highlights, it is not readable.
- OR, Press CTRL + F (Windows) or Command + F (Mac) and search for a word that appears in the document. If the word can’t be found in the search, the PDF can’t be read by assistive technology
What to do
First, make sure you have a copy of Adobe Acrobat Pro DC on your computer. The University provides a license to the full Adobe Creative Suite for faculty, students and staff.
PDFs are typically created from source documents created in a Microsoft Office or a Google product. The easiest way to make a pdf accessible is to create it from an accessible source document (or go back and edit the source doc to make it accessible, then reproduce the pdf).
Born accessible – make a PDF
Once you’ve determined that your source document is accessible:
- Use your chosen software’s native “File > Save/Download > Download as PDF” functionality to output a PDF
- Open it in Adobe Acrobat Pro and run the Accessibility checker
- Remediate if necessary based on the Accessibility checker results
Remediation: When you don’t have access to the source document
This happens a lot. To fix an inaccessible PDF use Adobe’s help documentation. It’s going to be the most up-to-date and accurate for your version of acrobat. Adobe: create and verify PDF accessibility
Remediation steps:
- Add metadata.
- Add and touch up tags.

- Fine-tune reading order and tab order.
- Check your work.
Remediation: Make a scanned document accessible
Use Acrobat Pro DC’s Optical Character Recognition (OCR) tool, then follow the remediation steps above.
