Accessibility belongs in ebook self publishing from the start, not as a last-minute technical check. An accessible EPUB is easier to navigate and read for people using screen readers, keyboard controls, magnification, or larger text—and thoughtful structure often improves the experience for every reader.
Accessibility is not a single switch you can turn on during conversion. It depends on the manuscript, the EPUB structure, and how the finished book behaves in reading apps. The good news: authors can address many common barriers with a few deliberate choices before and after conversion.
What makes an EPUB accessible?
An accessible ebook gives readers meaningful structure and usable content, rather than relying only on visual appearance. A heading should be identified as a heading in the document structure, for example, not merely styled to look large. That structure helps assistive technology users understand where they are and move through the book.
Accessibility also involves images, links, language, navigation, and the ability to change text size or display settings. An EPUB can pass a technical validation check and still be difficult for a person to use. Validation is important, but it does not replace a human review.
Requirements vary by market, platform, and the intended audience. Treat the practices below as a useful baseline, not a guarantee of legal compliance or a substitute for specialist accessibility testing where that is required.
Ebook self publishing: start with an accessible manuscript
Many accessibility improvements begin in Word. A well-structured DOCX is easier to convert reliably than a manuscript built from visual formatting alone.
Use real heading styles
Apply Word’s built-in heading styles to chapter titles and any meaningful subheadings. Use Heading 1 for chapter titles and a consistent lower level for sections within a chapter. Keep the hierarchy logical: do not jump from a chapter heading to a much deeper heading just because its appearance suits the page.
Body paragraphs should use the normal text style. Making a line bold or larger may change how it looks, but does not necessarily communicate that it is a heading to assistive technology.
Write useful image descriptions
For an image that adds information, provide concise alt text describing its purpose or essential content. A chart might need a short description of its main takeaway, while a character portrait in a novel may need little more than a relevant identification if the image itself matters to the story.
Not every image needs a description. A decorative flourish that adds no information should generally be treated as decorative, so a screen reader does not announce unnecessary details. Avoid repeating a caption word for word in the alt text unless that repetition serves a clear purpose.
Make links understandable out of context
Readers may navigate by jumping from link to link, without hearing the surrounding paragraph. Use link text that explains the destination or action, such as “Download the reading guide,” rather than “click here” or a raw web address. If a URL itself is important, introduce it clearly.
Keep language and text readable
Set the manuscript language correctly and mark meaningful changes in language when your authoring workflow supports it. This helps text-to-speech tools choose appropriate pronunciation. Use clear sentence structure where possible, explain unfamiliar abbreviations, and avoid using color alone to convey meaning.
Do not force a particular font size or page layout on readers of a reflowable ebook. Readers should be able to adjust text size and often font and spacing settings to suit their needs.
Build navigation that works for everyone
A clear table of contents is more than a convenience. It gives readers a quick way to reach chapters and other important sections without paging through the whole book. Make chapter names distinct and descriptive, and check that the navigation entries point to the correct places.
Front matter and back matter should also have a sensible order. Include relevant sections, such as a contents page or notes, in a way that makes them easy to find. Avoid using repeated blank paragraphs or decorative symbols as substitutes for structure. A screen reader may announce those elements in an unexpected or confusing way.
For a book with footnotes, endnotes, or many internal references, test the links in both directions where the format supports it. Readers should be able to reach a note from its reference and return to their place in the text without losing their position.
Check images, tables, and special content
Complex content often needs more attention than ordinary prose. Before conversion, review the following:
- Images: Confirm that important images are included, legible at typical screen sizes, and described appropriately.
- Charts and diagrams: Provide the key information in nearby text or a longer description when a brief alt description is not enough.
- Tables: Keep them simple where possible. Identify header rows clearly, avoid using tables just to position text, and check whether the information remains understandable on a narrow screen.
- Color: Do not distinguish categories only by color. Add labels, patterns, or text so the information remains available in other display conditions.
- Equations and symbols: Check how they are spoken by text-to-speech and whether readers can understand them without relying on visual placement alone.
Some content will not translate neatly to a small, reflowable screen. If a table is too wide, consider whether its information can be presented as a sequence of labeled items instead. The goal is not to preserve the exact appearance of the Word page at all costs; it is to preserve the meaning and make it usable.
Validate the EPUB, then test it with readers
After conversion, use a technical validator such as EPUBCheck to identify structural and packaging errors. Tools such as Ace by DAISY can also help detect common accessibility issues in EPUB files. These tools are useful, but automated checks cannot judge every alt description, confirm that an explanation is clear, or guarantee that every reading app behaves the same way.
Open the finished EPUB in more than one reading app if possible. Check that it opens, the contents links work, text can be resized, and navigation behaves as expected. Then try at least one assistive-technology review if it is practical for your project. A quick screen-reader pass can reveal missing headings, confusing link labels, or repeated decorative elements that a visual inspection may miss.
Keep a short record of what you tested: the EPUB version, validator results, reading apps, and any known limitations. This makes revisions easier and helps set accurate expectations if you share the file with a publisher, retailer, or accessibility reviewer.
A practical accessibility checklist before release
- Chapter and section titles use a consistent, logical heading hierarchy.
- The table of contents is present, readable, and linked to the right sections.
- Informative images have useful descriptions; decorative images do not add clutter.
- Links explain their destinations or actions.
- Book language and any important language changes are identified correctly.
- Tables, charts, notes, and symbols remain understandable in a reflowable layout.
- Readers can adjust text size without losing essential content.
- The EPUB passes a technical validation check and has been opened in a reading app.
- At least one human review has checked usability, not just file structure.
Where conversion fits into the accessibility workflow
Conversion carries structure from a manuscript into an EPUB, but it cannot decide whether a chart description is meaningful or whether a chapter heading is logically named. Review the source DOCX first, convert it, and then inspect the EPUB itself. If a change is made to the manuscript, regenerate the file and repeat the relevant checks.
ebookconvert.pro can convert a Word manuscript into an EPUB 3 and companion PDF, and its existing-EPUB workflow can validate or repair some file issues. Those steps can help with production, but they are not a replacement for a dedicated accessibility audit or testing with assistive technology. Keep that distinction clear when planning a release.
Accessible ebook self publishing is an ongoing practice
For ebook self publishing, accessibility is best handled as part of editing, conversion, and quality assurance—not treated as a promise that one tool can certify every reader’s experience. Start with meaningful document structure, write useful image descriptions, and check the EPUB in actual reading software. Then fix the barriers you find and document what you tested.
That approach cannot guarantee a perfect experience on every device, but it gives readers a more usable book and gives authors a concrete, repeatable process for improving each edition.
