Zstandard (ZST) is a modern fast compression algorithm developed by Facebook, offering real-time compression with high ratios.
Raw Disk Image (IMG) is a sector-by-sector byte copy of a disk or floppy drive, used for cloning and forensic imaging.
Reach for ZST when your priority is linux kernel builds, package compression, big data — its efficient compression makes sharing fast and storage minimal.
Reach for IMG when your priority is floppy disk backups, forensic disk imaging — its uncompromising quality ensures every detail is preserved.

No, converting ZST to IMG does not cause additional quality loss — IMG uses lossless compression. However, any artifacts already present in the original ZST file will persist in the IMG output.
IMG files are typically 2-5x larger than equivalent ZST files because IMG preserves all pixel data. This is expected and necessary for lossless quality.
