Technically, the spec does require it, but given that we’re in a thread about ecosystem support for a file format that’s approaching its 15th birthday, it’s worth considering how many image viewers will actually be able to work without the DCT step that is the essence of what typical JPEG does.
I don’t have a Windows machine handy to test, but it’s entirely possible that maybe lossless JPEG won’t display in its default viewer.
Yeah. I would imagine a better program actually has lossless compression if the format can do that. Like I mentioned initially, their own image viewer can’t even open WebP; but using the old one from XP/Vista opens them fine. 🤷♂️
JPEG also supports lossless compression.

Does it? Paint doesn’t seem to use it. Even saving something uncompressed adds artifacts that don’t exist in the raw.
You mean the Microsoft made program?
