This tool helps you spot issues that can make PDFs hard for people with disabilities to read or use, such as missing image descriptions or heading problems. You can see affected content highlighted directly on the page, review issues by severity, and get step-by-step instructions for fixing them. It also flags anything that needs a human reviewer. Upload PDFs up to 50 MB or paste a public link. It is completely free, with no sign-up, no email required, and no files stored. Checks against WCAG 2.1 AA and PDF/UA standards.
