Why Convert QOI to PNG file?

QOI (Quite OK Image) is a young, deliberately simple lossless format designed to encode and decode far faster than PNG, which makes it popular in game engines and custom tooling. The trade-off is reach — mainstream photo viewers, browsers, and editors mostly don't recognize it yet, so a QOI file is awkward to share or open anywhere outside the tool that made it.

Both formats are lossless, so nothing is discarded in the conversion — the pixels and any alpha transparency carry over exactly. The PNG will usually be somewhat smaller, since PNG spends more effort on compression than QOI's speed-first design does.
