SNB to SUN conversion is the process of transforming an ebook file in the SNB format (used by some e-reader apps as a zipped/packaged notebook or ebook container) into the SUN ebook format, which is a different container/layout used by other readers or publishing tools. This conversion extracts and remaps text, images, metadata, and layout so the content remains readable and navigable in SUN-compatible apps.

Keep individual SNB files under 250 MB for fastest, trouble-free conversion; larger files may be slower or require a premium service.
To preserve visual quality, choose lossless or low-compression SUN output when the SNB contains high-resolution images or scanned pages.

Note format-specific limitations: if the SNB is DRM-protected, you must remove DRM or use the original app to export content before converting; some interactive elements (annotations, embedded scripts) may not carry over to SUN.
