ELECTRONIC Publication to G4 conversion is the process of transforming an EPUB eBook container (which packages HTML/XHTML, CSS, images and metadata) into a G4 document format. This conversion repackages or renders the EPUB content into the G4 target structure and rendering rules so the resulting file is compatible with systems that require G4 documents.

ELECTRONIC Publication (EPUB) is primarily designed for reflowable digital books and publications, supporting rich text and multimedia content. In contrast, G4 is a highly compressed monochrome image format optimized for fax machines and scanned documents. While EPUB focuses on flexible reading experiences, G4 is best suited for efficient storage and transmission of black-and-white images.
Keep individual EPUB files under 100–250 MB for fastest, most reliable conversion; very large files may time out or require more memory.
Preserve quality by choosing the high-quality image embedding option and avoiding additional downsampling; for fixed-layout EPUBs select a conversion path that preserves page geometry.
Convert DRM-free EPUBs only; files with DRM will not convert unless the DRM is removed using legal methods.
For many files, convert in batches of 5–20 to balance throughput and server limits; large batch jobs should be split to prevent failures.
