Screen-reader readiness checks

PDF accessibility checker online, without uploading

Check whether a PDF has the basics a screen reader needs: tags, language, title, text layer, encryption status, and page-level issues. The check runs in your browser.

  • Checks common PDF accessibility signals.
  • Explains problems in plain language.
  • Runs locally, so the document is not uploaded.

What this checker can tell you

The checker looks for accessibility basics that often decide whether a PDF is usable by assistive technology: a text layer, document language, title metadata, tag structure, and encryption settings.

It is not a full human accessibility audit. It is a fast first pass that points out obvious blockers and explains what to fix next.

Why no-upload checking helps

Accessibility work often happens on policy documents, employee handbooks, medical forms, financial reports, legal notices, or public-sector documents. Local checking lets you inspect the file before sending it to a vendor, reviewer, or public site.

Common fixes

If the PDF is image-only, run OCR first. If it has no title or language, set those in the source document or PDF editor. If it lacks tags, the best fix is often exporting again from Word, InDesign, Google Docs, or another source that can create tagged PDFs.

How to use this workflow

  1. 01.Open the checkerDrop your PDF into the browser-based accessibility checker.
  2. 02.Read the reportReview tags, document language, title, encryption, text layer, and page-level scan warnings.
  3. 03.Fix the next blockerUse OCR for image-only pages, set document metadata in your source app, or rebuild the PDF from an accessible source file.

Questions

Does this prove my PDF is accessible?
No. It checks common technical signals and flags obvious blockers. A complete accessibility review may still need manual testing.
What does image-only mean?
It means the page appears to be a picture of text rather than real selectable text. OCR can add a searchable text layer.
Will the checker upload my document?
No. The PDF is inspected in your browser.
What should I fix first?
Start with the biggest blockers: image-only pages, missing text layer, encryption that blocks access, missing language, missing title, and absent tags.
