Yes, converting ORF to DDS 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.
DDS files are typically 50-80% smaller than ORF files because DDS uses efficient lossy compression. The exact reduction depends on quality settings.
No, DDS does not support transparency. Any transparent areas in your ORF will be filled with a solid color (usually white) during conversion. Use PNG or WebP if transparency is needed.
