About this tool
Check visible PDF accessibility hints locally before publishing, sharing, archiving, submitting, or sending documents to accessibility-sensitive workflows.
PDF Accessibility Checker inspects visible accessibility hints before a PDF is published, submitted, archived, or sent to a client. It reads the selected file locally in the browser and checks common signals such as tagged PDF hints, structure tree, document language, title metadata, image alternate text hints, forms, links, annotations, and encryption.
- Reads the selected PDF locally and checks common tagged PDF, structure tree, language, title, alt text, form, annotation, and encryption hints.
- Scores visible accessibility signals and labels the document as Ready, Review, or Needs work for the next remediation step.
- Does not upload the PDF and does not certify PDF/UA, WCAG, Section 508, or legal compliance.
How to use PDF Accessibility
Choose a PDF and review the accessibility hint score, status label, passed checks, and review notes. Use the result as a local precheck before running a full PDF/UA, WCAG, Section 508, or manual accessibility review in an authorized tool.
When this tool is useful
- Before publishing reports, brochures, manuals, forms, public notices, policy documents, or white papers.
- Before submitting PDFs to government, education, healthcare, enterprise, procurement, or compliance workflows.
- Before sending client-facing PDFs where tagged structure, language, titles, alt text, links, or forms need review.
Practical tips
- Treat missing tags or structure tree hints as a sign that reading order, headings, lists, and tables need a full accessibility review.
- Review image alternate text quality manually; a visible /Alt hint does not prove the text is meaningful.
- Use a full accessibility checker for PDF/UA, WCAG, Section 508, ADA, or legal compliance decisions.
Examples you can test
These examples show the kind of real input and reviewed output this tool is designed to support. Use them as a starting point before pasting your own production content, then compare the output with the destination system that will use the result. The goal is not only to produce a value, but to make the input assumptions, output format, and review step clear enough that the result can be trusted in a real workflow.
Precheck a public report before publishing
Example input
Annual-report.pdf with language metadata, title metadata, images, and no tagged PDF hint
Expected output
Labels the PDF as Review or Needs work and recommends a full accessibility remediation pass.
The checker identifies visible object hints only; reading order and semantic quality still require manual review.
Review a fillable PDF before submission
Example input
Application-form.pdf with AcroForm and widget hints
Expected output
Reports form field hints and reminds the user to check labels, tooltips, tab order, and instructions.
Accessible forms need more than visible fields; each control should have a clear programmatic label.
Validation checklist
Run through these checks before copying the result into a CMS, codebase, spreadsheet, campaign, support ticket, or production document. Small formatting differences, unit assumptions, hidden whitespace, and platform-specific rules are common sources of mistakes in quick browser tools, so the final review should happen in the same context where the output will be used.
- Confirm tags, structure tree, reading order, headings, lists, and tables in a full PDF accessibility checker.
- Review image alt text, artifact markings, link text, form labels, tooltips, and tab order.
- Set clear document language and title metadata before publishing or submission.
- Do not treat lightweight object inspection as PDF/UA, WCAG, Section 508, ADA, or legal certification.
Why people use this tool
PDF accessibility issues often appear late in publishing workflows: screen reader users cannot navigate content, images lack descriptions, forms have unclear labels, or agencies reject a submitted document. A local accessibility hint checker helps teams catch obvious preparation gaps without uploading sensitive files.
