Make your EPUB EU accessibility-ready — in seconds
Since June 2025 the EU Accessibility Act requires ebooks sold in the EU to be accessible, and stores can delist titles that aren't. Drop an EPUB below: we fix the machine-checkable requirements automatically and hand you a clear report and the corrected file.

What gets fixed
Writes schema.org accessibility metadata (access modes, features, hazards) and a human-readable summary — the fields EU stores now read.
Declares the document language and page titles on the package and every content file, so assistive tech reads the book correctly.
Finds images with no alt attribute and writes descriptive alt-text with AI, leaving your existing markup untouched.
Generates a proper EPUB 3 navigation document with a table of contents and landmarks if one is missing.
A whole catalogue? Use the API
Publishers with a backlist can remediate in bulk. Send a single EPUB to POST /api/v1/remediate or a zip of titles to POST /api/v1/remediate-batch, authenticated with your x-api-key header. You get the corrected files plus a per-title report you can keep for your records.

Honest about what this is
PaperbackKit is an automated accessibility service: it fixes and verifies the requirements a machine can check — metadata, language, alt-text, navigation and structure. Automated tools only cover part of accessibility; things like whether an alt-text truly describes an image, or whether reading order makes sense, still need a human eye. So this is a tool, not a legal certificate — responsibility for each published title stays with the publisher, exactly as it does with any formatting or publishing tool. We surface anything that needs a human look in the report.
