PDF Accessibility Checker — Free, No Upload, Browser-Based

PDF Accessibility Checker inspects your document for the key WCAG 2.1 and PDF/UA requirements that determine whether assistive technology can read it: a document title, a language declaration, bookmarks for navigation, and a tagged structure tree. Everything runs entirely in your browser — the file never leaves your device and no account is required.

Cómo usar esta herramienta

1. Open the tool and drop your PDF onto the upload area, or click to select it from your device.
2. Click "Check accessibility" to run the five-point inspection — title, language, bookmarks, MarkInfo, and structure tree — entirely in your browser.
3. Review the pass/warn/fail checklist and download the plain-text report to share with your team or document your audit.
