Understanding ePub and Mobi Formats
Before we delve into the formatting process, let’s briefly explore the differences between ePub and Mobi formats:
ePub (Electronic Publication)
- Open-source format: Developed by the International Digital Publishing Forum (IDPF), ePub is an open and free standard for digital publications.
