FICTIONBOOK to SUN conversion is the process of transforming an ebook stored in the FB2 (FICTIONBOOK) XML-based format into the SUN format used by certain ebook readers and software. This conversion preserves text, structure (chapters, sections, metadata) and common formatting while rewrapping or re-encoding resources to meet SUN file requirements for compatibility and display.

SUN format is optimized for lightweight e-book reading and is commonly supported by various e-reader software and devices.

Keep FB2 source files under 250 MB for fastest, trouble-free conversion; split very large multi-volume ebooks into parts when possible.
To preserve layout and images, choose the high-quality SUN output; for text-only reading select minimal to reduce file size.
For batch conversions, compress FB2 files into ZIP archives or use tools that support queued processing to maintain metadata consistency.
Note format limitation: SUN may not support every advanced FB2 styling or scripting—complex CSS-like styles and some interactive elements can be lost.
