PDF Accessibility Checker for Structure Signals

Use Accesserty DevCheck as a browser-based PDF accessibility checker for structure signals such as language, tags, links, images, form fields, bookmarks, and page consistency before deeper PDF remediation.

What this PDF accessibility checker can inspect

A PDF can look visually correct without exposing useful structure to assistive technologies. DevCheck focuses on structure signals so teams can decide whether to repair the source document, run deeper review, or export the PDF again.


  • Document language and tags

    Check whether the PDF exposes language information and tagged-page structure signals.

  • Links, images, and form fields

    Review links, images, and form fields to decide whether text alternatives, labels, or source-document fixes are needed.

  • Bookmarks and page consistency

    Inspect bookmarks and page-size consistency to identify long or merged documents that may need fuller review.

  • Local checking workflow

    PDF structure checks run in the browser and do not upload the PDF to Accesserty.

A PDF accessibility checker cannot replace complete PDF remediation

DevCheck does not remediate PDFs, automatically tag PDFs, certify PDF/UA conformance, or provide a legal compliance decision. It provides structure signals that help decide whether fuller manual review, source-document repair, assistive technology testing, or professional PDF remediation is needed.

Who should use this PDF accessibility checker?

  • Content and operations teams

    Check basic structure signals before publishing PDFs instead of relying only on visual layout.

  • QA and product teams

    Keep traceable PDF risk clues during document delivery, pre-release checks, or regression workflows.

  • Engineers and site maintainers

    Prioritize documents that need review when managing PDF downloads, forms, reports, or public notices on a website.

Frequently asked questions

Does DevCheck upload my PDF?

No. PDF structure signal checks run in the browser and do not upload the PDF to Accesserty.

Can DevCheck fix PDFs or automatically tag them?

No. DevCheck is a checker, not a PDF remediation tool. If the document lacks tags, alternatives, reading order, or form labels, the source document or PDF still needs to be fixed in an authoring tool.

Does passing this check mean the PDF conforms to PDF/UA or WCAG?

No. Structure signals help identify risk, but they do not prove that the PDF is fully usable, PDF/UA conformant, WCAG conformant, or legally compliant.
