Both formats, briefly
CBRIN
CBR stores comic pages the same way CBZ does, one image per page in reading order, except the archive is compressed with RAR instead of ZIP. It was among the first containers collectors used for scanned comics, so older libraries and long-running series are often still filed this way. RAR packs those pages a little tighter, at the cost of needing software that can unpack RAR at all. Upload a CBR here when you want the pages moved into something your current reader handles.
LRFOUT
LRF is Sony's own ebook format, also known as BBeB or BroadBand eBook, used across the Sony Reader line before the company switched to EPUB. It handles reflowed text, images, embedded fonts and simple styling, which covered what those devices were sold to do. You will mostly meet LRF in libraries bought from the old Sony store or synced onto a PRS-series reader. Convert it when you want those titles on hardware that never spoke Sony's format.
