Twitter rolls out high-quality 4K image uploads for all mobile users

Twitter is rolling this out to a limited number of people.

Update, Apr 21 (4 pm ET): 4K image support is rolling out for everyone

What you need to know

• Twitter is testing two photo-related tweaks on mobile apps.
• It’ll let users see how their photos will appear on the timeline as part of a change to the tweet composer.
• The company will also enable higher quality uploads, allowing for the sharing of 4K pictures.

Twitter is testing out an improvement to how its mobile app handles photos on Android. In a limited test the company announced today, there’ll be changes made to both the tweet composer and image upload quality.

The composer will now display a more representative view of an image you plan to share pre-upload. That is to say, you’ll now see how it would appear in the timeline before you upload it.

The second is a small tweak that’ll let you see and view 4K pictures on Android and iOS. It’s a step up from the compressed images that users can share now, and it’ll presumably help photography enthusiasts share their work more accurately.

In a collection of tweets, the company said:

Sometimes it’s better said with a picture or a video. Over the next few weeks, we’ll be testing some ways to improve how you can share and view media on Twitter. Now testing on Android and iOS: when you Tweet a single image, how the image appears in the Tweet composer is how it will look on the timeline –– bigger and better.
Have a collection of higher-res photos waiting to be shared? We’re testing ways for you to upload and view 4K images on Android and iOS.
If you’re in the test, update your high-quality image preferences in “Data usage” settings to get started.

Twitter and other social media platforms have prioritized speed over fidelity when it comes to images in the past. With companies now loading up “lite” apps for the best cheap Android phones such as the new Instagram Lite that debuted this morning, they’re free to now refocus the larger apps on more ambitious tasks, and this test is part of that.

Update, Apr 21 (4 pm ET) ― 4K image uploads are available for everyone

After testing the feature with some users, Twitter has announced that 4K image uploads are now available for all users on iOS and Android.

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
