Is it pronounced jay-peg or gee-peg?

What makes jpeg compression bad isn’t low bandwidth. It’s really good at compressing an image for that.

What makes jpeg bad is that the compression artifacts multiply when a jpeg gets screen captured and then re-encoded as a jpeg, or automatically resized and recompressed by a social media platform. And that definitely isn’t a problem that has gone away since dialup, people do that more than ever.

I'm not saying it's true, I obviously understand that not all jpegs are low quality and over compressed. That's just how the word is generally used by people, especially those outside of tech who aren't well versed in different image formats.

Not really? Unedited would be some sort of raw. JPEG usually implies preprocessed by the camera

Exactly. Image compression should excel at avoiding excess.

Though maybe some people think the JPEG committee is now creating spreadsheet formats...
