Accessible PDF Guide
Why PDF Accessibility Matters
PDF documents are one of the most common digital accessibility barriers. At UT Tyler, all digital content, including PDFs, must be accessible to individuals who use assistive technologies.
Following WCAG 2.1 AA supports compliance with Title II of the Americans with Disabilities Act (ADA), Texas Administrative Code 206 and 213, and helps ensure equitable access for students, employees, patients, and members of the public.
For UT Tyler, this means that any PDF or other document posted on a website, Canvas course, or web-based system is considered web content and must meet applicable accessibility requirements.
Should You Use a PDF?
Whenever possible, avoid PDFs. They are difficult to remediate and maintain over time. Use the guidance below to determine whether a PDF is appropriate or whether a more accessible format should be used.
PDF Decision Tree
|
1) Is this an existing PDF or new content? |
|
|
If Yes Existing PDF: Is the PDF still in use? |
If No Existing PDF that is not in use: Consider removing (deleting) or archiving this PDF. |
|
2) Is this content available through the library? |
|
|
If Yes Recommendation: use the library link for the resources needed rather than creating a PDF. |
If No Is this content from a third party resource (such as state or federal government) or a textbook?
If No: Is this a scanned document?
|
|
3) Is the content in this document updated or changed at least once per year (or more frequently)? |
|
|
If Yes Recommendation: Do not use a PDF. Continue to question 4 to consider other file formats. Note: Once you edit the source file of a previously remediated PDF, accessibility formatting may be compromised. The PDF must be manually rechecked and fixed each time edits are made, which makes PDFs inefficient and expensive to maintain. |
If No Continue to question 4. |
|
4) Was this file originally created in Microsoft Office? |
|
|
If Yes Do you have access to the original source document for the PDF?
Note: If you are using a PDF because the file needs to be distributed in a protected or locked format, you can share Microsoft files as read only to communicate that the document should not be edited.
|
If No Continue to question 5. |
|
|
|
|
5) Is this a text based document that can live in an alternative format in Canvas or on a UT Tyler website? |
|
|
If Yes Course content in Canvas: Using the Canvas Rich Content Editor, transfer the content into your course, run the accessibility checker, and fix issues as needed. Website content: Is the content for broad use at UT Tyler or for the general public?
|
If No Continue to question 6. |
|
|
|
|
6) Is this PDF a form with fillable fields? |
|
|
If Yes Was the form created by your department?
|
If No Continue to question 7. |
|
|
|
|
7) Is this file used as an infographic or flyer? |
|
|
If Yes Is it being shared in an email or a Marketing and Communications message?
If you created in Adobe InDesign, Adobe Express, or Canva: Using accessibility features within Adobe InDesign can reduce the effort of remediating a finished PDF in Acrobat. Canva has some accessibility features, including PDF auto tagging, but they are not WCAG compliant and will still require manual remediation in Adobe Acrobat. |
If No Continue to question 8. |
|
|
|
|
8) Does this document need to be printed? |
|
|
If Yes If providing a PDF for printing purposes only, identify to the recipient that it is For Print Only. Also include for-print-only as part of the PDF file name. If a version exists for digital distribution (webpage, Word document, email, and similar formats), make sure all information in that version is accessible.
|
If No Evaluate the PDF for accessibility and remediate if needed. Work with the EIR Accessibility Coordinator to see whether someone can remediate the PDF. If not, engage an external PDF remediation service (at your unit's expense) following UT Tyler purchasing procedures. |
|
|
|
|
9) You have determined that the document must remain a PDF. |
|
|
Creating a new PDF: Follow UT Tyler guidance for producing accessible PDF documents (start with an accessible source file, then export, then verify in Acrobat). Remediating an existing PDF: Work with the EIR Accessibility Coordinator for assistance to remediate the PDF. If internal support is not available, engage an external PDF remediation service (at your unit's expense) following UT Tyler purchasing procedures. |

What Makes a PDF Accessible?
Creating Accessible PDFs (Microsoft Word)
Start With an Accessible Source File
- Use built‑in headings
Apply headings from the Styles pane instead of using bold fonts. - Use built‑in list styles
Use built-in numbered or bulleted lists, not dashes or typed numbers. - Add alternative text to images
Right‑click the image, select Edit Alt Text, and describe the image’s purpose. Mark decorative images as decorative. - Use meaningful link text
Replace bare URLs or “click here” with text that describes the destination. - Ensure sufficient color contrast
Verify text contrast and avoid using color alone to convey meaning. - Set the document language
Use Review → Language → Set Proofing Language. - Run the Microsoft Accessibility Checker
Review and fix errors before exporting.
Convert Correctly (Word and PowerPoint)
Use File → Save As → PDF, click Options, and ensure "Document structure tags for accessibility"
is checked.
Do not use Print to PDF, as it strips all accessibility features from the document.
Remediating Existing PDFs (Requires Adobe Acrobat Pro)
- Run the Acrobat Accessibility Checker
Open the PDF in Adobe Acrobat Pro and run the Accessibility Checker to identify errors, warnings, and items that require manual review. - Add or repair tags
Use the Tags panel to add missing tags or correct existing tags so the document structure accurately reflects headings, lists, tables, and content order. - Set the document title and language
Specify the document title and primary language in File Properties so assistive technologies can correctly announce the document. - Fix the reading order
Review and adjust the reading order using the Reading Order tool to ensure content is read in a logical, meaningful sequence. - Add alternative text to images
Provide appropriate alternative text for meaningful images and mark decorative images as artifacts. - Repair table structure
Ensure tables use proper header cells, scope, and structure so relationships between data cells are conveyed to screen reader users. - Verify color contrast
Confirm that text and important visual elements meet minimum color contrast requirements and do not rely on color alone to convey meaning.
Manual review and testing are required even after automated checks.
Quick Testing PDFs for Accessibility
- Adobe Acrobat Accessibility Checker
- Keyboard navigation using the Tab key
- Screen reader testing using NVDA (Windows), Narrator (Windows), or VoiceOver (iOS)
- Zoom to 200 percent to confirm readability
Special Cases and Considerations
Scanned Documents
Scanned PDFs are image‑only documents and are not accessible unless Optical Character Recognition (OCR) is applied.
- Open the scanned PDF in Adobe Acrobat Pro and run OCR using All Tools → Scan & OCR → Recognize Text → In This File.
- After OCR completes, use Autotag Document to create an initial tag structure.
- Review the document for OCR errors and correct inaccurate text.
- Add alternative text and verify reading order using the Reading Order tool.
Note: OCR is not fully accurate. Poor scan quality, complex layouts, or unusual fonts may require significant manual correction.
Forms
PDF forms require additional accessibility features beyond standard document remediation.
- Ensure all form fields have clear, descriptive labels.
- Verify a logical tab order through all fields.
- Include instructions and meaningful error messages.
- When possible, provide an accessible alternative such as an HTML form.
Mathematical Content
Mathematical equations present unique accessibility challenges.
- Use MathML when possible to provide accessible, machine‑readable equations.
- If MathML is not available, provide detailed alternative text describing the equation.
Example: “An algebra equation: x squared plus three equals nineteen.”
Multi‑Column Layouts
Screen readers read content in tag order rather than visual order, which can cause issues in multi‑column layouts.
- Review and adjust the reading order to match the intended sequence.
- Test the document using Adobe's Read Out Loud or a screen reader.
- Consider single‑column layouts for complex documents.
