: Identifying errors in the "tag tree" that might prevent screen readers from interpreting content correctly. Metadata & Settings
: Verifying that the document includes necessary metadata and isn't restricted by settings that limit accessibility. Platform Accessibility : Because it is web-based, it is a primary solution for
and smartphone users who cannot run the Windows-only PAC desktop application. How it Fits into the Workflow
is powerful for identifying automated failures, it is typically used as one part of a broader accessibility strategy: Automated vs. Human
: It catches machine-verifiable errors, but human review is still needed to ensure alt-text is meaningful and the reading order is logically correct. Remediation : Unlike some paid plugins,
provides a report of errors but does not include tools to fix them directly within the interface. Integration
: For organizations needing to check high volumes of documents, axes4 also offers for automated, bulk processing.
