Free PDF Accessibility Testing

An accessible document is a file, such as a PDF, that everyone can read and use — including people who use a screen reader, navigate only with a keyboard, or rely on magnification software. This includes correct structure tags, alt text for images, a logical reading order, and a defined document language, among other things.

Document accessibility is for anyone who struggles to consume digital content in standard form—such as blind or low-vision users who rely on screen readers, people with motor disabilities who use keyboard navigation, and those with reading difficulties who use assistive tools. In practice, an accessible document is more usable for everyone.

The system focuses on PDF documents that are published on your website and publicly available — PDFs are the most common source of accessibility issues on websites. For other file types, like Word documents or presentations, feel free to reach out to us through the contact form.

The system checks every public document it discovers by crawling your site. The report notes the scope of discovery and any access limitations, so you know exactly which documents it's based on.

An automated check quickly identifies common technical issues across every document on your site. A manual check complements it with usability, context, and reading-order testing — things that are harder to detect automatically.

Every document receives a score from 1 to 10 based on the findings within it: 10 means the document is fully accessible, and a low score points to significant gaps that need attention. The score helps you quickly prioritize which documents to start with.

No. The check identifies and documents the issues; the actual fix can be done in editing tools like Adobe Acrobat or Word, or through AccessiDoc, which offers making PDF documents accessible for free. If you'd like guidance through the fix process, feel free to reach out using the form below and we'll be happy to help.

No. The report is a professional tool for spotting gaps and prioritizing fixes against requirements like WCAG, PDF/UA and EN 301 549, but it is not a certificate of compliance and does not constitute legal advice. For a full compliance review — including an ADA compliance audit for US-facing organizations — we recommend also using manual testing and professional legal advice.

The scan duration depends on how many documents are on your site. A small to medium site typically takes a few minutes; larger sites with hundreds of documents may take a little longer.

The initial scan and the mapping file are completely free. If you need more in-depth support — like manual testing or help fixing your documents — we'd be happy to talk and put together a solution that fits your needs.

Yes. You can re-run the scan at any stage, see how the scores and statuses have changed, and confirm that the fixes actually resolved the issues that were found.

Most websites don't have an organized list of every document published over the years, and old files stay online without anyone remembering they're there. The simplest way to find out is to run an automated scan of your site: the tool at the top of this page crawls your website, finds every public PDF file on it, and brings them together for you in a single report — including the page count and date for each document.

A manual check requires a screen reader and knowledge of the standard's requirements, but you can get a quick read without that too: our automated accessibility checker for PDF scans every document for structure tags, alt text, reading order and language settings, and gives it an accessibility score from 1 to 10 — so you'll know right away which documents are in good shape and which need attention.

Once our report shows which documents need attention, you can get PDF accessibility testing and remediation for free at AccessiDoc — just upload a document and we make it accessible at no cost.

Yes. While our law section above focuses on EU legislation, the same PDF accessibility checks — structure tags, alt text, reading order and color contrast — are also central to ADA compliance in the United States, since US courts and regulators generally point to WCAG as the practical standard. Many organizations use our report as the starting point for an internal ADA compliance audit, treating it as a preliminary ADA compliance audit tool for their PDF library before bringing in outside legal counsel.
