Following a test the company ran in March, Twitter users on both iOS and Android can now upload and view images at 4K. To do so, all you need to do is navigate to the “Data usage” section of the settings menu and update the selection on the high-quality images option. Of course, if you’re worried adding 4K images to your timeline will slow down your doomscrolling or make a dent against your data cap, you can keep things as is.
Time to Tweet those high res pics –– the option to upload and view 4K images on Android and iOS is now available for everyone.
To start uploading and viewing images in 4K, update your high-quality image preferences in “Data usage” settings. https://t.co/XDnWOji3nx

At around the same time this past March, Twitter started testing full-sized picture previews with a small subset of Android and iOS users. Currently, the platform automatically crops images to save space on the timeline. If you’re in the test, uploading a single image to your timeline will leave it unaltered. According to a Twitter spokesperson, that test is still ongoing with the company recently expanding it to include more people.
