Telegram Android app: Open the chats list, click the menu icon and select “New Channel.” Telegram desktop app: In the upper left corner, click the Menu icon (the one with three lines). Select “New Channel” from the drop-down menu. 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. 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. Telegram users themselves will be able to flag and report potentially false content.
