The optimal dimension of the avatar on Telegram is 512px by 512px, and itβs recommended to use PNG format to deliver an unpixelated avatar. A Telegram channel is used for various purposes, from sharing helpful content to implementing a business strategy. In addition, you can use your channel to build and improve your company image, boost your sales, make profits, enhance customer loyalty, and more. Your posting frequency depends on the topic of your channel. If you have a news channel, itβs OK to publish new content every day (or even every hour). For other industries, stick with 2-3 large posts a week. To upload a logo, click the Menu icon and select βManage Channel.β In a new window, hit the Camera icon.
