DocAccessible vs veraPDF

DocAccessible helps teams check, rebuild, review, publish and exchange accessible documents through web and API. It can provide hosted accessible HTML and a rebuilt tagged PDF from remediated content. Automated checks map to WCAG 2.2 AA, while generated PDFs are PDF/UA-aligned rather than certified for conformance. The browser editor supports changes to headings, alt text, reading order, captions and table structure, then reruns checks when changes are saved. Exchange provides case-scoped vendor access, review and approval steps, version history and controlled delivery links; vendor remediation fees are separate. Website monitoring finds public PDF links and tracks source changes, but conversion and publication are separate actions. Security controls described include private production object storage, upload scanning with ClamAV, scoped permissions and versioned records. The Free plan accepts files up to 10 MB; Pro accepts files up to 50 MB. Plans range from free to $199 a month, with paid plans from $19 a month. There is no free trial.

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.
