About JPG
JPEG (Joint Photographic Experts Group)
A lossy image format standardized in 1992 that shrinks photos by discarding detail the eye is less likely to notice. It has no transparency, and each re-save loses a little more quality. Use it for photos you want to share or upload, since nearly every device, browser and app opens it.
About QOI
Quite OK Image Format
A lossless image format published by Dominic Szablewski in 2021, designed to encode and decode much faster than PNG at similar file sizes. Its whole specification fits on one page. Use it in games and tools that load many images and care more about decode speed than support in other apps.
