CommonLook PDF vs veraPDF

CommonLook PDF helps organizations remediate PDFs for accessibility and compliance. Users can choose an advanced or simplified editor based on their experience and document complexity. AI-driven tagging assists with tables, lists, forms, and other elements, while manual tagging tools and a Fix Wizard support review and correction. The software provides PDF tagging, reading-order, and alternative-text tools, and validates against WCAG, PDF/UA, and HHS standards. It can generate bookmarks from document headings and supply a downloadable Validation Report showing passed, failed, and warning issues. A system of record tracks remediation history and lets users remove older files or download accessible PDFs with their reports. The desktop version is an on-premises plugin for Adobe Acrobat Pro or Pro DC. Allyant offers live and on-demand training and a CommonLook Knowledge Base. The product is designed for users of every ability and organizations addressing requirements such as Section 508, ADA Title II, and the EAA. Pricing is available on request, and a seven-day trial is listed.

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.
