What is the PDF Audit API?

Document accessibility, as an API call

The EqualWeb PDF Audit API is a comprehensive solution for automating PDF accessibility. It lets organizations, developers and enterprises audit, remediate and certify PDF files for conformance with the leading international accessibility standards - from inside their own systems, CMS or document workflows.

By building these checks into your pipeline, documents can ship accessible by default - instead of being fixed one by one after the fact.

How it works

Upload. Audit. Report. Remediate.

One REST workflow takes a document from upload to a remediated, standards-aligned download.

  1. Upload

    Authenticate and securely upload PDFs through REST endpoints - individual files or batches for enterprise-scale workflows.

  2. Audit

    A comprehensive scan evaluates the document against WCAG, PDF/UA, Section 508 and other relevant regulations:

    • Document structure and logical reading order
    • Semantic tagging - headings, paragraphs, tables, lists
    • Alternative text for images, graphics and charts
    • Accessible forms with labeled fields
    • Color contrast and design compliance

  3. Report

    A detailed accessibility report classifies every element:

    Passed Needs Review Failed

    Fully compliant elements, items for manual validation, and issues that must be remediated.

  4. Remediate & download

    The API doesn't just detect - it fixes. AI-powered remediation applies structural tags, generates alt text and corrects errors. Download the remediated PDF, aligned with WCAG, PDF/UA, ADA, Section 508 and EN 301 549.

FAQ

PDF Audit API - frequently asked questions

What is the EqualWeb PDF Audit API?
The EqualWeb PDF Audit API is a REST API that lets organizations, developers and enterprises automate PDF accessibility from their own systems: upload documents, audit them against standards such as WCAG 2.1/2.2, PDF/UA (ISO 14289), ADA, Section 508, EN 301 549 and the European Accessibility Act, apply AI-powered remediation, and download the fixed, standards-aligned file.
Which accessibility standards does the PDF Audit API audit against?
The API evaluates documents against the leading international standards: WCAG 2.1 and 2.2, PDF/UA (ISO 14289), the ADA, Section 504 and Section 508 of the Rehabilitation Act, EN 301 549 and the European Accessibility Act (EAA), the Accessible Canada Act and AODA, the UK Equality Act 2010, Australia's Disability Discrimination Act, the New Zealand Web Accessibility Standard, and Germany's BITV 2.0.
Does the PDF Audit API fix documents or only report issues?
Both. The audit classifies every element as Passed, Needs Review or Failed - and AI-powered remediation then applies structural tags, generates alternative text for images and corrects errors automatically. The remediated PDF is available for download, and EqualWeb's certified experts can handle complex cases that need human judgment.
Can the PDF Audit API process documents in batch?
Yes. The REST endpoints support individual uploads and batch processing for enterprise-scale workflows, so organizations can audit and remediate large document libraries - thousands of PDFs - through the same integration.
How do I integrate the PDF Audit API into my system?
Integration is a standard REST workflow: authenticate, upload PDFs to the audit endpoint, poll or receive the report, and download remediated files. It fits any modern stack, CMS or document pipeline. Contact EqualWeb to get API credentials and the developer documentation.
