"Wechat avatar faded" reached the top of Weibo hot search, the official response said that "related functions have been optimized"

According to news from CTOnews.com on February 12, "Wechat profile Portrait faded" topped Weibo's most popular search today. Some netizens reported that Wechat avatar had faded, and the clarity and color of the Wechat profile photo were dimmed compared with the original picture for a period of time. Some netizens speculated that it was caused by compressing the quality of the picture.

In response, Wechat officially responded to Caijing Technology: "A small number of Android users have responded that they will switch back to the original avatar by selecting 'View last avatar' in the avatar settings interface, and the color of the avatar that has been set up many times will fade." the relevant functions have been optimized and restored as soon as possible. "

CTOnews.com looked at Wechat and found that the Wechat profile picture format is PNG, which is a bitmap format that uses a lossless compression algorithm. However, Wechat itself compresses the avatars uploaded by users, thereby reducing the file size.
