Product Overview: Telegram
Telegram is a multi-platform, cloud-based messaging service designed to provide fast, secure, and feature-rich communication for individuals, groups, and communities. Founded by Russian-born entrepreneur Pavel Durov, Telegram has grown to become one of the most popular messaging apps globally, with over 950 million active users.
Core Functionality
Telegram allows users to send text messages, photos, videos, and files of any type, including documents (.DOCX, .MP3, .ZIP, etc.), up to 2 GB in size. It supports voice and video calls, both one-on-one and in groups, with end-to-end encryption to ensure privacy and security.
Key Features
Security and Privacy
Telegram prioritizes user privacy and security through several measures:
- End-to-End Encryption: All chats, including secret chats, are encrypted using a combination of 256-bit symmetric AES encryption, 2048-bit RSA encryption, and Diffie–Hellman secure key exchange. Secret Chats can be programmed to self-destruct automatically, and they prevent screenshots to enhance privacy.

Telegram is accessible on multiple platforms, including iOS, Android, Windows, macOS, Linux, and web browsers, allowing users to sync their messages across all devices seamlessly.
Group and Channel Management
- Groups: Users can create groups with up to 200,000 members. These groups support features like replies, mentions, hashtags, pinned messages, and moderation tools. Group admins can manage membership, delete messages, and set default permissions.
- Channels: Telegram allows users to create public or private channels for broadcasting messages to an unlimited number of subscribers. This feature is popular among news organizations, bloggers, and content creators.
