edited message on telegram Send Uncompressed Media without Changing the File Extension One of the worst parts about messaging apps is that anyone can add you to random groups without your active permission. However, the good part is that Telegram gives you an option to disable it altogether. You can change the desired settings from Settings menu -> Privacy and Security -> Groups -> My Contacts and then select all the Telegram users to “Never Allow”. I can’t tell you how much I love this Telegram trick.

Signal Vs. Telegram: Which Secure Messaging App Is Better? The encryption is based on 2048-bit RSA encryption, 256-bit symmetric AES encryption, and Diffie–Hellman secure key exchange.

Telegram just offers a good marriage of popularity and security for those with concerns over other messaging apps. To create your own theme, tap the three-dot button (Android) or go to Chat Themes (iOS) and choose Create new theme. Here, you can create your own look if you don't like any of the default options.

In Telegram, you can adjust the color and background. If you like, you can even set up your own custom theme to make Telegram look exactly the way you like. Keep Alive If you prefer keeping the sensitive content of your chats limited to yourself and avoiding it from being intercepted by a hacker or the authorities in your country or region, this Telegram trick is for you. While normal chats in Telegram are user-to-server encrypted and cannot be read unless someone breaches Telegram’s servers, Secret Chats take it to a new level by providing user-to-user encryption. These chats are meant to be short-lived and not stored on Telegram’s servers. Now tap on Notifications and mute the contact for either a custom period of time or forever. I generally leave it for forever.

There are many astonishing features that set Telegram messenger apart from other messaging services. For instance, you can coordinate groups of up to 200,000 members, send documents of any type, destruct your messages with a timer, or even build your own tools on their API. Improvements for Everyone
