Overview
We convert manuscripts and print into clean EPUB3 that works across Kindle, Apple Books, Google Play and library platforms — reflowable or fixed-layout. Accessibility is built in: reading order, navigation, alt-text and MathML equations.
Every e-book is validated with epubcheck and accessibility-checked with ACE by DAISY, so it passes retailer ingestion and meets the European Accessibility Act.
Why KPR Knowledge
Why accessible EPUB is now essential
Since 28 June 2025 the European Accessibility Act requires e-books sold into the EU to be accessible. A converted EPUB that stores equations as images or lacks structure can be rejected or pulled from sale.
We build the accessibility in during conversion — far cheaper than remediating later — and give you an ACE report as proof.

FAQ
Frequently asked questions
Do your EPUBs meet the European Accessibility Act?
Yes — EPUB3 to EPUB Accessibility 1.1 and WCAG 2.1 AA, validated with ACE by DAISY.
Reflowable or fixed-layout?
Both — the right approach for each title.
Do you handle maths in EPUB?
Yes — equations are MathML, navigable by screen readers, not images.
