Better Portable Graphics (BPG) is a modern image format based on HEVC video compression, offering excellent compression efficiency.
Silicon Graphics Image (SGI) is a raster image format developed for SGI workstations, supporting high-quality rendering and scientific visualization.
Reach for BPG when your priority is web images with superior compression — its efficient compression makes sharing fast and storage minimal.
Reach for SGI when your priority is legacy sgi workstations, 3d rendering — its uncompromising quality ensures every detail is preserved.

No, converting BPG to SGI does not cause additional quality loss — SGI uses lossless compression. However, any artifacts already present in the original BPG file will persist in the SGI output.
SGI files are typically 2-5x larger than equivalent BPG files because SGI preserves all pixel data. This is expected and necessary for lossless quality.
Yes, SGI supports transparency. Alpha channel information from BPG is preserved during conversion.
