Twitter has raised the limits of image sizes, as the resolution increased fourfold from about 4 megapixels to 16 megapixels, and this would allow users to enlarge images better if the screen was large enough to take advantage of the new details possible.
Twitter usually reduces the quality of the images to save space, as Twitter programmer Nolan O'Brien announced the change in the tweet chain, and the change applies to images uploaded through the web version of Twitter only.
The change in image resolution may seem a slight improvement, but it may be important, as the user may ignore many low-resolution images, and each pixel can be counted when you want to dive into a beautiful landscape, or examine a leaked product image to try to see if it is real Fake mother.
And sometime in 2020, Twitter will also increase the size of profile photos, which today are limited to 400 x 400 pixels.
