Twitter developers changed the process of uploading images, so now photos in JPEG format will not be
What is known
Twitter engineer Nolan O’Brien in his accountwrote about the latest changes and attached a photo as an example. Previously, during image upload, images were transcoded, which made the quality worse. JPEG images will now be saved in the images. Thumbnails and previews will still be compressed, and information about the place and time of shooting will be deleted.
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: //t.co/1u37vTopkY pic.twitter.com/Eyq67nfM0E

So far this only works with the computer version of Twitter, but in the future the update will reach smartphones. Also, developers plan to change other images and formats.
“Other categories of images (such as avatars) will receive the same improvement in the new year.” - Nolana O’Brien
