Starting today, Twitter will preserve JPEGs as they are encoded for upload on Twitter for Web. (Caveat, cannot have EXIF orientation) For example: the attached photo is actually a guetzli encoded JPEG at 97% quality with no chroma subsampling. https://en.wikipedia.org/wiki/Guetzli pic.twitter.com/Eyq67nfM0E

Ah yes, thank you. It's both 2 and 3. Using a D850 which produces w > 8000 and I export down to 15MB. Seems large but is already compressed coming from 60MB.

wow -- that's quite the source image! If you can drop it down to under 4096x, it should preserve quite beautifully.

Congrats and amazing job! These were actually the important details I was looking for!! So photos of roughly 12MP, and at or under 5 MB won’t have any transcoding when displayed in full? That’s huge. Is there any scenario that would trigger chroma subsampling?
-
If we trigger a transcode, we will apply chroma subsampling. No transcode will mean no subsampling.
