This announcement makes sense to me, having done something similar before personally (1). The difference between a screenshot of a photo saved as a PNG and a JPG is huge, usually over 1MB, and I'm sure Twitter gets plenty of these. Publishing their thresholds for the JPG vs PNG size comparison instead of referring to it just an internal metric would clear up some disconnect. Plus, I'd love to improve the static values I chose if there is better data available. I doubt the people working on this project wanted to change any PNG unless it's clear cut but the line has to go somewhere. These will be better handled by JPG. Numbers about avg file size would be awesome too, how much data will this save in a typical user session? 1 - https://engineeringblog.yelp.com/2017/06/making-photos-smaller.html https://engineeringblog.yelp.com/2017/06/making-photos-small...
