Convert EPUB to IDML

Understanding EPUB and IDML file formats

EPUB (Electronic Publication) is a widely used eBook file format that supports reflowable content, making it adaptable to various screen sizes and devices. It is commonly used for distributing digital books and publications.

IDML (InDesign Markup Language) is an XML-based file format developed by Adobe for Adobe InDesign. It allows users to exchange and edit documents in InDesign, supporting advanced layout and design features.

Why convert EPUB to IDML?

Converting an EPUB file to IDML is useful when you want to edit or enhance an eBook's layout and design using Adobe InDesign. This conversion enables publishers and designers to leverage InDesign's powerful tools for print or digital publishing.

How to convert EPUB to IDML

Direct conversion from EPUB to IDML is not natively supported by most software. However, you can use a two-step process:

1. Import EPUB into InDesign: Use Adobe InDesign (version CC 2019 and later) to open or place EPUB content. Go to File → Open or File → Place and select your EPUB file. InDesign will import the content, though formatting may require adjustment.
2. Export as IDML: Once the EPUB content is in InDesign, go to File → Export and choose IDML as the export format. Save the file to complete the conversion.

Recommended software for EPUB to IDML conversion

• Adobe InDesign: The industry standard for professional publishing, supporting both EPUB import and IDML export.
• Third-party plugins: Tools like Recosoft PDF2ID or Markzware IDMarkz can assist in converting EPUB or other formats to IDML, though results may vary.

Tips for a successful conversion

• Check and adjust formatting after importing EPUB into InDesign, as complex layouts may not transfer perfectly.
• Use styles and master pages in InDesign to streamline the editing process.
• Always save a backup of your original EPUB file before conversion.
