Public channels are public to the internet, regardless of whether or not they are subscribed. A public channel is displayed in search results and has a short address (link). The optimal dimension of the avatar on Telegram is 512px by 512px, and itโs recommended to use PNG format to deliver an unpixelated avatar.
