SNB to RGF conversion is the process of transforming an ebook stored in the SNB (Seebook Notebook) container format into the RGF (Rich eBook Graphic Format) ebook format, preserving text, images, and layout where possible. This conversion rewraps content and may transcode embedded assets so the resulting RGF file can be opened in RGF-compatible readers and devices.
