Twitter engineer Nolan O’Brien said that Twitter will preserve JPEGs as they are uploaded. This means that uploaded images will retain their original quality.
It’s a small change that has the potential to make a big difference to the way photographers view and use the platform. Nolan’s thread has inevitably kick-started a conversation about plans for other image formats and user-requested changes, so Twitter could make itself even more photo-friendly soon.
Another interesting note is that Twitter automatically strips EXIF data from photos, which I didn’t know. This is nice because this metadata can contain private information, such as where the photo was shot.
