How Do I Check If My PDF Is Accessible?

Check PDF accessibility with a combination of file inspection, supported automated validation and human review. No fixed two-minute, five-minute or thirty-minute check establishes accessibility for every document.

Inspect the file first

Confirm whether text can be selected or extracted and whether it matches the visible content. A selectable layer can still contain recognition or encoding errors. Inspect the document title, language, tags and meaningful alternatives. For informative images, an empty alternative-text field is a finding to investigate; some images are decorative or explained elsewhere.

Check keyboard navigation of links and form fields. Tab order concerns focusable elements; it is not a complete test of the reading sequence of ordinary text. Inspect the tag sequence and reading order separately.

Use a supported validator

Consult PAC documentation and veraPDF accessibility profiles for the current release and supported standards. Adobe Acrobat also provides checking and editing workflows. Record the exact version, profile and result rather than asserting a universal rule count or checker ranking.

The Matterhorn Protocol describes PDF/UA-1 failure conditions, including human checks. It is a testing model rather than an application. Passing an implemented automated subset does not establish complete PDF/UA or WCAG conformance.

Complete manual and task-based review

Check meaningful image descriptions, heading roles, table-header relationships, reading sequence and content preservation. Test relevant tasks with the PDF reader and assistive technologies students use. A preview or single screen-reader check cannot certify every environment.

Fix and reassess the actual output

Correct the source or saved candidate, then evaluate those exact bytes again. Retain the original, output identity, findings, manual decisions and unresolved work. Do not upload sensitive or licensed content to an online service without the institution's authorization and data-handling review.

Aelira Core is beta software. Supported workflows can apply eligible partial fixes and record outcomes, but some inputs need manual work or cannot produce a downloadable remediated file. Review the actual saved output, unresolved findings and content preservation before publication. Automated scores describe implemented checks rather than accessibility conformance. Inspect the public source and release documentation and evaluate a representative authorized sample before planning a rollout.
