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?

Yes: Review the 3Rs Review Strategy: Retire, Replace, Remediate. Continue to question 2.

If No

Existing PDF that is not in use: Consider removing (deleting) or archiving this PDF.

New content: Continue through the decision tree to determine whether a file type other than PDF will work.

 

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 Yes: If possible, contact the source and ask for a persistent link to accessible content or, for publishers, ask for an accessible ePUB or eBook version.

If No: Is this a scanned document?

  • If Yes: Use Adobe Acrobat to export the scan to a Microsoft Word (.docx) file. After reviewing and remediating the document, share the acessible version.
  • If content does not transfer well, contact the Microsoft Disability Answer Desk for assistance.
  • If No: Continue to question 3.
 

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?

  • If Yes: Recommendation: Share, post, or publish the original Microsoft Office file after verifying it is accessible. It is much easier to make these files accessible than it is to remediate them as PDFs.

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: Consider exporting your PDF to Microsoft Word or PowerPoint via Adobe Acrobat. After reviewing and remediating the file, share the accessible version.

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 Yes: Transfer the content directly into the appropriate UT Tyler website. Contact the UT Tyler Web Team for assistance adding content to webpages.
  • If No: Continue through the decision tree to consider other options for this content.

 

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 Yes: Turn it into a Qualtrics form or Microsoft Form.


Note: Google Forms does not guarantee data privacy. Qualtrics and Microsoft both offer secure data collection, and Qualtrics is best suited for research surveys or longer forms with extensive options.

  • If No: If this is an external PDF form produced by a government agency (for example tax forms or legal documents), link to the form on the government site rather than posting the PDF directly on a UT Tyler site.

 

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 Yes: If you are distributing the PDF as an email attachment, ensure it is accessible and also include the text and important information in the body of the email or message so everyone can access the information.
  • Social media: Attached files or images should have alt text.
  • If you link to the PDF from a mass email: Continue to question 8.

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.
