Why do people still use The jpg/jpeg format instead of PNG for photos in 2025? (sh.itjust.works)

Especially when they use websites like Reddit which allows for unlimited space for photos.

PNG is lossless, but also very inefficient with size if there's anything detailed going on

My camera produces 26 megapixel images, the JPEGs it makes are about 1-2MB. It also creates RAW format files that contain everything about the camera sensor at the point the image was taken, this is the most possible information I can have about the image, and it weighs about 50MB.

A 26 megapixel PNG of a photo takes up about 70MB, and it's got less information in it than the RAW

(Slightly hyperbolic example) If you were scrolling on your phone and it needed to load in images around the 70MB mark, you're not gonna have a remotely snappy experience.
