PDF Accessibility Checker

A free on-device pre-check for common machine-verifiable PDF accessibility signals, including title, language, tags and structure, likely image-only pages, links, and form fields. The PDF, filename, text, hash, and local path are not uploaded. Automated results do not certify WCAG, PDF/UA, Section 508, or legal compliance. Reading order, alternative-text quality, complex tables, contrast, and assistive-technology testing remain manual.
