Flexible Image Transport System (FITS) is a scientific data format used primarily in astronomy for storing and transmitting images and datasets.
DirectDraw Surface (DDS) is Microsoft's texture compression format for 3D graphics, extensively used in video games.
Reach for FITS when your priority is astronomy, scientific imaging, research — its uncompromising quality ensures every detail is preserved.
Reach for DDS when your priority is video game textures, 3d rendering — its efficient compression makes sharing fast and storage minimal.

Yes, converting FITS 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 FITS 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 FITS will be filled with a solid color (usually white) during conversion. Use PNG or WebP if transparency is needed.
