Telegram has rapidly become one of the world’s most favored messaging apps, offering powerful features, advanced privacy tools, and cloud-based convenience. But what does telegram do? Whether you're not used to the platform or interested in learning what sets it apart, this short article breaks down everything you should know.
📱 What Is Telegram?
Telegram is really a free messaging app that allows users to deliver text messages, multimedia, documents, and make voice/video calls over the web. It was launched in 2013 by Pavel Durov, while using mission to provide fast, secure, and censorship-resistant communication.
Unlike a number of other messaging platforms, Telegram offers cloud-based storage, meaning your messages and media sync across your devices automatically.
🔧 How Telegram Works – Core Features Explained
1. Account Setup
Users register using their number, but communication can occur using usernames, keeping your number private.
Telegram supports multiple devices — you can use the same account in your phone, tablet, desktop, and internet browser simultaneously.
2. Cloud-Based Messaging
Telegram stores your chats and media in the cloud (except Secret Chats).
This means you could start a conversation on your phone and continue it on the computer without losing any messages.
It also allows unlimited storage, so you can send large files (around 2GB) without cluttering your device.
3. Chat Types
Private Chats: One-on-one encrypted messages between users.
Group Chats: Chatrooms with up to 200,000 members, well suited for communities and collaborations.
Channels: Broadcast-only platforms for sharing messages with unlimited subscribers (ideal for news, media, updates).
Secret Chats: End-to-end encrypted chats stored only on the device (and not on Telegram's servers) and support self-destruct timers.
4. Security and Privacy
Telegram uses its very own encryption protocol called MTProto.
While regular chats are encrypted server-side, Secret Chats use end-to-end encryption for max privacy.
Users can enable two-step verification, build passcodes, and control that can see their number, last seen, or profile photo.
5. Media and File Sharing
Telegram allows sharing of:
Photos & videos
Documents (around 2GB per file)
Voice & video messages
Location and contact info
Everything shared is synced and backed up via Telegram’s cloud servers.
6. Bots and Automation
Telegram supports bots — automated accounts that could perform various functions like search, games, payments, or customer care.
Bots may be added to chats or employed in groups and channels to enhance interactivity.
7. Customization and Add-Ons
Users can personalize the app with themes, animated stickers, chat folders, and custom emojis.
Telegram includes a built-in media player, poll creator, and even mini-app support.
8. Voice and Video Calls
Telegram provides high-quality voice and video calls.
Calls are encrypted and work smoothly even on slow internet connections.
