Accessibility is a priority

The De Marque team produces reformattable EPUB 3 files that contain the accessibility features necessary to meet the needs of readers with disabilities and visual impairments.

What does accessibility enable?

A reader with a disability or visual impairment can use specialized reading applications that allow them to enjoy reading without any loss of meaning or context. An accessible EPUB makes it easier for assistive applications to clearly identify sections and content of ebooks and convey them to readers.

For example...

Identifying visual details, such as italicized text.

Reading alternative text of images.

Adding markers to help the reader navigate in complex layouts.

The importance of accessibility is undeniable

Ebook accessibility is an increasingly important issue, as some countries are planning to make accessibility mandatory within the next few years.


For example, France has decreed that all ebooks to be sold in the country must be accessible by 2022. The European Union will apply this requirement throughout its entire jurisdiction by 2025.
