Nonprofits, schools, government departments and most B2B vendors have an accessibility obligation — either a regulatory one or a contractual one. The good news is that almost everything WCAG asks for in a flipbook context is a checkbox in the tool's settings. The bad news is that nobody reads the settings panel until a reviewer flags the document. Here is the short version of what to check before publishing.
The six checkboxes
One: alt text on every image (not just the cover). Two: WebVTT captions on every audio track and embedded video. Three: heading hierarchy that goes h1, h2, h3 in order, with no skips. Four: colour contrast of at least 4.5:1 for body text and 3:1 for large text. Five: keyboard navigation that lets a reader flip pages, open hotspots and close dialogs without a mouse. Six: a 'skip to content' link that bypasses the page-flip controls for screen readers. Most flipbook tools either ship these on by default or expose a single toggle that turns them on as a bundle. The settings panel is usually called 'Accessibility' or 'Reader experience'.
The free auditing tools
After publish, run the URL through axe DevTools (browser extension), Pa11y (command line) and the WAVE evaluator (web tool). Each catches a slightly different set of issues; running all three takes ten minutes and produces a punchlist you can fix in another twenty. The vast majority of issues these tools flag are missing alt text and low-contrast typography — both fixable in the source PDF in less than a coffee break.
What to put in the accessibility statement
Publish an accessibility statement at /accessibility on your custom domain that names the WCAG level you target (AA is the standard), the date of the most recent audit, and an email address for users who need a particular issue fixed. The page does not need to be fancy; the act of publishing it tells your reviewers and your users that you take the obligation seriously, which is most of the credibility battle.
