This accessibility checker helps you find problems that can make PDFs hard for people with disabilities to read or use, like missing image descriptions and issues with headings. It shows affected content directly highlighted on the page, lets you review issues by severity, and gives clear instructions for fixing each one. The tool also points out the things that still need a human judgment call. You can upload PDFs up to 50 MB or paste a public link to check a file. It's completely free, with no sign-up, no email needed, and no files stored. Checks are run against WCAG 2.1 AA and PDF/UA standards.
