Accessibility across every template

Publishers can choose the FlowPaper template that best suits their publication while benefiting from accessibility support in the reader. This update extends WCAG 2.1 compatibility across the full range of templates, giving readers a more consistent experience.

Cross-tested with accessibility tools

FlowPaper 4.1.5 has been cross-tested with multiple third-party accessibility testing tools, including Google PageSpeed Insights and A11yPulse.

A note about publication content

Template compatibility is one part of an accessible reading experience. The accessibility of a finished publication can also depend on its source document, content, and configuration. FlowPaper 4.1.5 brings WCAG 2.1 compatibility to every viewer template, but that does not automatically mean every source document or publication conforms to WCAG.

We have no control over the contrast or type of font you use in your documents so to make sure you’re always compliant, run your PDF document through accessibility testing tools before publishing.
