Free PDF accessibility checker
Drop in one or more PDFs to see which accessibility basics are missing. Your files are read in your browser and never uploaded.
Drag PDF files here or choose them below (up to 25 files, 50 MB each).
Automated indicators only. This tool finds common, machine-detectable problems. Passing it does not mean a document meets WCAG, PDF/UA or the ADA. Reading order, alt text quality and link text need a person, and colour contrast needs a person to confirm.
Results
Problems detected by automated checks only. A file with none detected may still be inaccessible. This is not a compliance result.

Need every PDF on your website checked?
This checker handles files you pick. We are considering a service that scans a whole site, tracks new documents, and reports what needs fixing. It does not exist yet: leave an address and we will email you once if we build it.
