Telegram download & install FAQ

Yes. All installers are mirrored from Telegram's official release channels (desktop.telegram.org, macos.telegram.org, telegram.org/android). Nothing is repackaged, re-signed or bundled with additional software.

Yes. One-to-one voice and video calls, group voice chats and video conferences up to 1,000 participants are supported on every desktop and mobile edition.
