The optimal dimension of the avatar on Telegram is 512px by 512px, and it’s recommended to use PNG format to deliver an unpixelated avatar. 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). Select “New Channel” Done! Now you’re the proud owner of a Telegram channel. The next step is to set up and customize your channel. Write your hashtags in the language of your target audience.
