Yes, converting SGI to BPG uses lossy compression, which reduces file size by discarding some visual data. Set quality to 85-95% for a good balance of quality and file size.
BPG files are typically 50-80% smaller than SGI files because BPG uses efficient lossy compression. The exact reduction depends on quality settings.
No, BPG does not support transparency. Any transparent areas in your SGI will be filled with a solid color (usually white) during conversion. Use PNG or WebP if transparency is needed.
