Since 28 June 2025, the European Accessibility Act (Directive (EU) 2019/882) has applied across the EU — and for the first time it places digital accessibility obligations on the ebooks most publishers sell to consumers. If you distribute EPUBs into any EU market, accessibility has moved from a nice-to-have to a condition of sale.

This guide explains, in plain terms, what the EAA asks of an EPUB, what “accessible” means technically, and how to get there without rebuilding your whole catalogue. It is practical guidance for publishing teams, not legal advice — for questions about your specific obligations, exemptions, or timelines, check the text of the Directive and your national transposition with a qualified adviser.

The European Accessibility Act and ebooks: where things stand today

The European Accessibility Act has been in force since 28 June 2025. It is not upcoming legislation and it is not a proposal: it is the law that applies right now to ebooks placed on the EU market for consumers, and to the reading software they are sold with. If you are reading this looking for a deadline to plan against, the deadline has passed — what remains are the transitional arrangements for content already on sale, which are defined at national level and which several member states extend as far as 2030.

That distinction matters for how you plan. An ebook published or re-published into an EU market today needs to be accessible on the day it goes on sale. An ebook that was already on sale before 28 June 2025 may sit inside a transitional window — narrower than most publishers assume, and not the same length in every member state. The practical read: treat every new title as in scope from day one, and treat the backlist as a remediation programme with a national deadline you need to confirm rather than a permanent exemption. That confirmation is a question for a qualified adviser; this guide is practical guidance for a publishing team, not legal advice.

What the EAA requires of ebooks

The EAA is a single EU directive that sets common accessibility requirements for a range of products and services, including e-books and the software used to read them. In practice it means that most ebooks made available to consumers in the EU on or after 28 June 2025 must be produced and sold in an accessible format, with the accessibility information disclosed to the buyer. You can read the directive itself on EUR-Lex.

The obligation is broad but not unlimited. It applies to products placed on the market from the application date, so parts of an existing backlist may fall under transitional arrangements, and some very small operators — for example microenterprises that only provide certain services — can be out of scope. These carve-outs are narrow and defined at national level, so treat them as something to confirm, not to assume.

What an accessible EPUB means in practice

The EAA describes outcomes, not file formats. The recognised way to meet it for ebooks is EPUB Accessibility 1.1, the W3C standard, which in turn builds on WCAG 2.1 level AA. Hit those two and you are aligned with what regulators, retailers and reading systems expect. You can read the standard at W3C.

Concretely, an accessible EPUB has meaningful alternative text on images that carry information, a logical heading structure, a correct reading order, the content language declared, data tables marked up as tables rather than as layout, and a working navigation document (nav). These are the elements a screen reader, a refreshable braille display or a text-to-speech engine relies on to make the book usable.

Accessibility metadata: the part stores now show

One change catches many publishers by surprise: accessibility metadata. EPUB Accessibility 1.1 expects each file to declare, in schema.org terms, how accessible it is — through properties such as accessibilityFeature, accessibilityHazard, accessMode and a human-readable accessibilitySummary.

This is no longer invisible plumbing. Major retailers and library platforms now surface this metadata on the product page, so a reader can see before buying whether a title has alt text, structured navigation or any flashing-content hazard. Missing or dishonest metadata is both a compliance gap and a lost sale.

How to check and fix an EPUB

The reference checker is Ace by DAISY, the open-source tool from the DAISY Consortium. It audits an EPUB against EPUB Accessibility and WCAG and produces a detailed report of what passes and what fails. It is the same engine the wider industry trusts, so its verdict is one retailers and aggregators recognise.

Origami runs Ace for you and then goes a step further. Mechanical problems — missing language declarations, absent or incomplete accessibility metadata, and some structural fixes — can be repaired with AI-assisted tooling in place. Anything that needs editorial judgement, above all writing alt text that actually conveys what an image means, is flagged for a human rather than guessed at. The result is fewer manual passes and a file you can stand behind.

A year on: what should already be done, and what can wait

The advice has not changed; the clock has. More than a year past the application date, new production should already be born compliant — if an EPUB you publish today still needs a remediation pass, that is the first thing to fix, because every month it stays that way adds to the backlist. After that comes what is actively on sale into the EU, starting with the titles carrying the most images and tables, where the accessibility gaps are widest and the cost to the reader is highest.

What can wait is narrower than it was. Transitional periods, the disproportionate-burden provisions and micro-operator exemptions all still exist, but they are time-limited, evidence-based, and set by each member state rather than by the Directive itself. The safe default is unchanged: assume a consumer ebook needs to be accessible, document your reasoning wherever you rely on an exception, and confirm the transitional deadline that actually applies in the markets you sell into.

Frequently asked questions

Does the European Accessibility Act apply to ebooks, or only to e-readers?
Both. The Directive covers e-books and dedicated software as well as the devices and reading systems used to access them. In practice that means the EPUB file itself has to be accessible, and the app or platform selling and rendering it has to be accessible too — publishers own the first half, and are increasingly asked by retailers to evidence it.
When does the EU Accessibility Act apply to ebooks?
The Directive has applied since 28 June 2025. Ebooks placed on the EU market for consumers on or after that date generally need to be accessible, though transitional arrangements can affect some existing content. Confirm specifics against your national transposition.
Does the EAA apply to my backlist?
Potentially. The rules bite when a product is made available on the market, so titles you keep selling are in scope even if they were first published years ago. Some transitional and disproportionate-burden provisions exist, but they are limited — plan to remediate the backlist you actively sell.
What standard makes an EPUB accessible?
In practice, EPUB Accessibility 1.1 together with WCAG 2.1 level AA. That covers alt text, heading structure, reading order, declared language, proper tables, navigation and accessibility metadata.
Which tool should I use to test accessibility?
Ace by DAISY, the DAISY Consortium’s open-source checker, is the industry reference. Origami runs Ace and adds AI-assisted repair for the mechanical issues it finds, so you go from report to fix in one place.
Can AI make my EPUB compliant automatically?
Partly. AI reliably fixes mechanical items such as language declarations, metadata and some structure. Meaningful alt text and other editorial decisions still need a human, which is why Origami flags them for review instead of auto-filling them.
Is being technically accessible enough to be compliant?
Technical conformance is the core of it, but the EAA also expects accessibility information to be disclosed to buyers, which is where accurate metadata matters. Treat this as practical guidance, not legal advice — verify your obligations with the Directive and an adviser.

What has changed in this guide

We update this guide when the rules or the way they are applied change, not when the page design does.

  1. Reframed around a law in force rather than one coming: the EAA has applied since 28 June 2025. Added an opening section on scope for new ebooks against backlist and on the national transitional arrangements, and rewrote the backlist priorities for a year after the application date.
  2. First published.

The bottom line

The EU Accessibility Act turns EPUB accessibility from best practice into a baseline for selling into Europe. The technical target is clear — EPUB Accessibility 1.1 and WCAG 2.1 AA, with honest accessibility metadata — and most of the work is checkable and, increasingly, automatable. Test with Ace, fix the mechanical issues fast, reserve human attention for alt text and judgement calls, and build accessibility into production so every new title ships compliant.
