Telegram has announced a number of measures aiming to tackle the spread of disinformation through its platform in Brazil. These features are part of an agreement between the platform and the country's authorities ahead of the elections in October. 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. Done! Now you’re the proud owner of a Telegram channel. The next step is to set up and customize your 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. You can invite up to 200 people from your contacts to join your channel as the next step. Select the users you want to add and click “Invite.” You can skip this step altogether.
