How to Create a Private or Public Channel on Telegram? It’s easy to create a Telegram channel via desktop app or mobile app (for Android and iOS): 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. Select: Settings – Manage Channel – Administrators – Add administrator. From your list of subscribers, select the correct user. A new window will appear on the screen. Check the rights you’re willing to give to your administrator. Telegram channels enable users to broadcast messages to multiple users simultaneously. Like on social media, users need to subscribe to your channel to get access to your content published by one or more administrators.
