This is the most important and best feature of the Telegram Messenger app. Telegram makes use of MTProto, which is a protocol built on time-tested algorithms. Telegram enables high-speed delivery of messages even when the user is experiencing a weak connection. This protocol is divided into three components namely; the High-Level component, the Cryptographic Authorization component, and the Transport component.

In addition to this, the Telegram Messenger supports two layers of secure encryption. These are a combination of 2048-bit RSA encryption, and 256-bit symmetric AES encryptions, plus Diffie–Hellman Secure key exchange. Moreover, the chats, groups, media, files, or text are all encrypted in the same way. This protects messages and files when intercepted unless these were deciphered.


Telegram Bots

These are computer programs that have a wide range of capabilities. You can code these bots to add new features and enhance your experience while using Telegram. Moreover, if a user has good programming skills, they can write and publish their own bots to automatically perform some tasks.


Telegram Bot API

This is what the third-party developers use in creating their custom bots. With this bot API, users can make a bot for a simple task. Moreover, it will be possible for them to come up with more advanced uses like merging with third-party apps including WordPress, payment services, and social media platforms.


Support for Larger Groups

Telegram allows creating groups that can have up to 200,000 members per group. Also, it supports mentions, hashtags, and replies, which help provide structure, thus maintaining order and keeping communication to larger groups. With that, the members can easily search for any message posted within the group.

Moreover, the admin of the group can pin some messages on the top of the group that everybody can see. They can also mass-delete messages and restrict members from posting forbidden messages. in addition to this, there can be public groups wherein anyone can join and can help in discussions and collecting feedback. There can also be private groups wherein anyone can be an administrator and set a custom file.



This feature allows you to disseminate messages to a large number of Telegram users. It can accommodate an unlimited number of subscribers. This is a great feature as admins are the only ones who can post content. Moreover, it helps the developer to send important information, keeping its users updated with the latest news. Channels provide a convenient way to reach people directly by sending notifications to their devices. Users can have options to join and leave channels anytime they want.

In addition to this, Telegram supports two types of channels. The first type is public, and the other one is private. Users can find public channels through search and anyone can join them. On the other hand, private channels can be joined only through invitation links.


Polls and Quizzes

A feature that are great additions to any group or channel you preside over. You are allowed to create not only anonymous but also visible votes wherein the creator can let everyone in the group see who voted for what. You can also set up quizzes with multiple answers, which is the best way to settle scores with your family and friends by allowing the members to select multiple answers.


Scheduled Messages

This feature allows you to send messages in advance, and you can specify the exact time and date you send it. With this, you can schedule your messages on your preferred date. This way, your “Saved Messages” will turn into reminders. It will then help you finish your tasks at a given time.


Silent Messages

This feature lets you send messages without sound. You are free to send messages to your friends even when they are busy or when they are in a meeting. The receiver of the message will receive a notification. However, their device will not make a sound even though their phone is in General mode.


Auto-Night Mode

If you prefer using dark themes at night, you should enable auto-night mode. This feature helps in a way that when you turn it on, the app won’t blind you at night. You have three options to choose from. There’s the System Default on Android or System on iOS, which matches the theme to the mode of your operating system. You can choose Scheduled, wherein the app will automatically switch to dark mode at your scheduled time.

Also, you can choose Adaptive if you are using an Android device, or Automatic if you are using an iOS device. In this option, the auto-night mode will automatically switch based on the ambient lighting conditions. However, you can still define the sensitivity using the slider.


Searching for Friends by Username

Telegram Messenger lets you register a unique username that people can search so that they can message you or add you to groups even if they do not know your phone number. This is great if you want to hide your contact details. For your security, you can disable uninvited messages in the app’s settings. If you don’t want to set a username, you don’t need to do so.


Chat Lock

As part of focusing on users’ privacy, this feature allows you to lock your chats. Doing this, you can protect your personal chats when anyone else borrows your device. No one can see your private conversations, for you can hide them using a passcode.


Sharing Live Locations

This feature allows you to share your live location with your contacts for your selected time limit. The time limit can be 15 minutes, one hour, or eight hours. Sharing your location is very useful for others to know your exact location, see your progress on your destination, and even watch out for your safety.


Slow Chat Mode

You can use this feature if you find it hard to manage your group due to a large volume of messages. This helps in making the conversations more orderly since it limits the frequency of messages that everyone sent. With that, it can effectively improve the quality of group chat because it will increase the value of each member and individual messages. You can choose the time interval when the members will have a restriction to send a message. A timer will be shown for the countdown of the next message.


Adding People and Groups Based on Location

This feature allows you to discover users and groups near you, and you can add them without sharing your mobile number. Also, with this feature, you can make location-based groups wherein the users within your location can view the created group on their device, and so they can join. Moreover, this will help you to find several groups with members of the same interest.


Secret Chat

This feature lets you keep the sensitive content of your chats to yourself and protects it from being intercepted by a hacker. Also, it allows you to secretly chat with someone, and everything that is transmitted is encrypted. This is to make sure that the intended recipient is the only one who can read the message. Moreover, when using the secret chat, you and the other party can’t forward the messages that you received. Also, screenshots and screen recordings are not allowed, and the chats are automatically deleted after being received and read.

In addition to this, the secret chats can only be accessed on the device where they originated. With that, if you used your smartphone for secret chats, you can only access the chats on that particular smartphone.


Self-Destruct Messages on Secret Chats

Uncompressed Media

Sending uncompressed media in other messaging apps is a bit troublesome. This is because you need to convert or change the media extensions into another format like EXE of PDF. On Telegram, you can always send uncompressed video and images on the fly. This makes sharing different types of media easier for Telegram users.


Multi-Platform Support

Users can access Telegram on multiple devices simultaneously. Not only is it available on Android and iOS devices, but it is also accessible on Windows phones, Windows PC, Mac OS, and Linux OS. Also, there’s a web-based version. Through this multi-platform availability, users can always connect to their loved ones using any platform. More importantly, you can download and use it for free.

When using Secret Chats, conversations will not be stored in their servers, and you can set a time limit until they get deleted. Also, only the two people involved can access the chats. On the other hand, voice calls are automatically encrypted, which make them as secure as MTProto permits.

Also, it provides MTProto security wherein messages that arrive in Telegram are encrypted. Regarding privacy, upon registration, it requires its users to provide their phone numbers to avoid spammers and bots from mass-registering.
