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. To upload a logo, click the Menu icon and select “Manage Channel.” In a new window, hit the Camera icon. Avoid compound hashtags that consist of several words. If you have a hashtag like #marketingnewsinusa, split it into smaller hashtags: “#marketing, #news, #usa. Choose quality over quantity. Remember that one high-quality post is better than five short publications of questionable value. But a Telegram statement also said: "Any requests related to political censorship or limiting human rights such as the rights to free speech or assembly are not and will not be considered."
