Fruition PDF Accessibility vs veraPDF

Fruition PDF Accessibility is a web and API service for remediating PDF structure and adding AI-based content tags. Upload a valid PDF or submit it through the REST API, which accepts up to 100 pages per request and returns a remediated file. Structural remediation sets metadata, marks the PDF as tagged, adds a PDF/UA-1 identifier, sets tab order, builds structure and parent trees, checks page resources, and generates bookmarks. AI analysis identifies headings, paragraphs, lists, and tables, adds semantic tags and image alt text, and analyzes color contrast. The service targets WCAG 2.2 AA, PDF/UA-1, Section 508, and ADA compliance. Structural work is listed at under 2 seconds per document; AI content tagging takes 30–60 seconds. The free plan is free for 10 pages per month with basic structural remediation. Basic is $0.50, paid once after the monthly free pages; Full AI is $2, paid once and includes structural fixes and AI features.

veraPDF is an open source validator for PDF/A and PDF/UA conformance. Its Implementation Checker validates all PDF/A parts and conformance levels, and performs machine checks for PDF/UA parts 1 and 2. The Policy Checker evaluates PDF Features Reports against institutional policy profiles. A Metadata Fixer makes a limited set of repairs, such as removing an incorrect PDF/A flag or repairing broken XMP when that is the only obstacle to a legitimate flag. The Reporter transforms machine-readable reports from the Implementation Checker, Policy Checker, and Metadata Fixer into other forms for downstream use. Developers can use the validation library as a Java archive through Maven, a desktop GUI, or a command-line application. Plugins can add third-party feature extraction tools to PDF Features Reports. The project describes digital preservationists and memory institutions as key users, and offers an API and test files for developers. Desktop installers are available for Windows, Mac, and Linux; these systems need Java 8 or later. veraPDF is dual licensed under GPLv3 or later and MPLv2 or later. Downloads include GPG signatures and instructions to check installer integrity. Development builds may contain bugs or missing features and come without support or guarantees. The validator costs nothing.
