What Telegram Desktop does
Telegram Desktop is the open-source desktop client for Telegram's connected messaging service on Windows, macOS, and Linux. It signs in to a Telegram account and uses Telegram's cloud for standard chats, media, groups, channels, bots, and cross-device history. Installing a desktop package does not provide offline messaging; account authorization, synchronization, calls, file transfer, updates, and normal use require connectivity.
Standard Telegram cloud chats are not end-to-end encrypted. Telegram's Secret Chats are device-specific, are not cloud-synchronized, and are not available in Telegram Desktop, so this page does not attribute Secret Chat end-to-end encryption or self-destruct controls to the desktop client. Bots are third-party programs that can receive data sent to them and must be reviewed separately. File-size limits, call features, Premium benefits, and platform behavior can change.
This record retains older Telegram Desktop 7.1.3 release assets published in the official tdesktop GitHub repository: Windows x64 installer and portable ZIP, macOS DMG, and Linux x86_64 tar.xz. The Linux item is an upstream binary archive rather than a distribution-native package, and portable means no installer—not no files, updates, account state, or network use. The SHA-256 values are reference digests in the official GitHub release-asset metadata, rechecked on 2026-09-11. The release is not marked immutable. This audit did not install the packages, inspect code signatures, or authenticate to Telegram.
