To upload a logo, click the Menu icon and select “Manage Channel.” In a new window, hit the Camera icon. The main design elements of your Telegram channel include a name, bio (brief description), and avatar. Your bio should be: Choose quality over quantity. Remember that one high-quality post is better than five short publications of questionable value. 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. Hashtags
