G3 to SNB conversion is the process of converting image files encoded in the G3 format (a group 3 fax/bi-level image compression standard) into the SNB format (a page-based eBook/document image container often used for scanned books and notes). The conversion repackages the bi-level raster data and metadata from G3 into the SNB container, preserving page order and enabling easier viewing in SNB-compatible readers.

G3 files typically have a MIME type of image/fax and use the ITU-T Group 3 fax compression codec, mainly for scanned black-and-white images. SNB files are used as a digital book format and may include various embedded media types with MIME type application/x-snb. The conversion process re-encodes the original data into the SNB format to optimize for accessibility and storage.

The G3 format is older and primarily used for fax and scanned documents, whereas SNB is a newer format designed for enhanced digital reading experiences. While G3 files tend to be larger and less flexible, SNB files support better compression and richer features. Converting G3 to SNB ensures improved compatibility and file efficiency across platforms.
Keep individual G3 pages under 5 MB where possible to speed up processing; overall multi-page jobs work best when total size is under 200–500 MB.
To preserve maximum clarity for text and line art, convert G3 bi-level data losslessly into SNB; avoid dithering or aggressive thresholding unless you need smaller file sizes.
For large archives, use batch conversion tools that accept folders of TIFF/G3 files and produce a single multi-page SNB to maintain page order and metadata.
Note format limitation: G3 is bi-level (black-and-white) only; converting to SNB with color will rasterize into grayscale or color frames, which can increase file size.
