JPEG images on Twitter for desktop are about to begin looking a bit sharper.

Senior staff software engineer Nolan O’Brien said in a series of tweets late Tuesday that the social network will now preserve JPEGs as they are encoded when they are uploaded to Twitter for the web, rather than transcoding them, which results in lower-quality display.

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
