SIMPLE, CLEAN AND COMPATIBLE EPUBS
This application was designed with a focus on creating simple, organized and compatible EPUB files.

Generated files use a clean structure that prioritizes compatibility, accessibility and validation. Whenever possible, the application follows EPUB accessibility best practices, helping improve compatibility with modern reading systems.

The goal is to provide a lightweight and practical tool for writers, students, teachers, independent authors and anyone who wants to create digital books without dealing with complex software.

IMPORTANT
This application was designed for creating and editing simple EPUB files.

Although it can import and edit existing EPUBs, some files created by specific software may use advanced CSS, embedded fonts, complex layouts, proprietary features or unconventional structures.

In such cases, part of the original formatting may not be fully preserved after editing or exporting.

This affects only a small number of EPUB files with uncommon structures. The vast majority of standard EPUB files can be imported, edited and exported normally.

If your goal is to create EPUB books, edit existing EPUB files, organize chapters, add images, insert tables, create internal and external links and export valid files compatible with major EPUB readers, this application was developed for you.

Create books. Edit EPUBs. Export valid files. All directly on your device.
