Lossless conversion
If the conversion path supports lossless mode (e.g., PNG to PNG, WAV to FLAC), JPG to PNG preserves every byte of detail. Where the formats fundamentally differ in what they can represent, "lossless" is impossible by definition — but JPG to PNG's "quality" preset gets visually indistinguishable for most content.
