WCAG (Web Content Accessibility Guidelines) are international standards for accessibility, ensuring digital content is accessible to everyone.

Who needs WCAG-compliant PDF files?

Public authorities and organizations are legally required to make their documents accessible. It also benefits all users.

What is PDF/UA and how does it relate to WCAG?

PDF/UA (ISO 14289) is the technical standard for accessible PDFs — the document-specific way to meet WCAG. The tool tags structure, adds alternative text and fixes reading order so the file conforms to PDF/UA.

Do your PDFs pass PAC?

PAC (PDF Accessibility Checker) is the recognized gold standard for verifying PDF/UA. Our output is built to pass PAC — download the result and check it in PAC yourself.

How do I make an existing PDF accessible?

Upload the PDF, review the issues found, add alternative text and fix structure in the wizard, then download the accessible PDF. Most of it is automatic.

What if a document can't be fixed 100% automatically?

For complex documents you can generate a guaranteed-accessible version where each page gets an OCR text layer — so the file always passes PDF/UA.

Is the WCAG test free?

Yes, you can test and make your PDFs accessible for free on PDF.dk.

What does the EU Accessibility Directive require of PDFs?

EU accessibility law — the Web Accessibility Directive for the public sector and the European Accessibility Act for many private businesses — requires digital documents to be readable by screen readers. For PDF that means PDF/UA in practice: tagged structure, alternative text, correct reading order and sufficient colour contrast.

What does it cost to make a PDF accessible?

An agency typically charges per document for manual work. On PDF.dk you do it yourself for free: upload the file and the tool fixes the bulk of the issues automatically. Testing and making your PDFs accessible costs nothing.

Can I make my PDF accessible myself?

Yes. The whole flow runs in your browser — no consultant, no Acrobat Pro and no technical knowledge required. Upload the PDF, follow the wizard, and download the accessible file.

Can scanned PDFs be made accessible?

Yes. A scanned PDF is just an image with no text. The tool can add an OCR text layer to each page so the content can be read by a screen reader and the file passes PDF/UA.

What is the WCAG colour-contrast requirement?

WCAG 2.1 requires a contrast ratio of at least 4.5:1 between text and background (3:1 for large text). The check flags text in your PDF that falls short.
