SNB to G4 conversion is the process of transforming an ebook saved in the SNB (Samsung eBook) container into the G4 ebook format, which is optimized for devices and platforms that support G4. This conversion extracts and rewraps text, images, metadata, and table-of-contents information so the content remains readable and navigable in G4-compatible readers.

SNB files are often limited in compatibility and tend to have larger file sizes. In contrast, G4 files provide better compression and broader support across platforms, making them more versatile for everyday use. While SNB is suitable for specific applications, G4 is ideal for general use and sharing.
Keep individual SNB source files under 200–300 MB for fastest, most reliable conversion; larger files may be slower or require splitting.
To preserve layout and typography, enable font embedding and use low image compression when exporting to G4; if file size matters, choose medium compression.
For large collections, use batch conversion with a queue: convert a small test file first to confirm settings, then process the rest.
Note format-specific limitations: SNB may contain proprietary DRM or Samsung-specific interactive features (annotations, widgets) that may not transfer to G4.
