Frequently asked questions
Everything you need to know about downloading, installing and using Telegram safely across your devices.
Is Telegram free to download and use?+
Yes. Telegram is completely free on Windows, macOS, Android, iOS and the web. There are no ads, no subscription fees and no hidden charges for the core messaging features.
How do I download and install Telegram on Windows?+
Open the download page, click 'Download for Windows', then run the installer (tsetup.exe). Follow the on-screen steps, launch Telegram and sign in with your phone number. Installation usually takes under a minute.
Is Telegram safe and secure to use?+
Telegram uses server-client encryption for cloud chats and end-to-end encryption for Secret Chats. You can also enable two-step verification, set self-destruct timers and control who sees your phone number and last-seen status.
What is the difference between a cloud chat and a secret chat?+
Cloud chats are synced across all your devices and backed up securely on Telegram's servers. Secret Chats are end-to-end encrypted, tied to a single device, are never stored on servers, and support self-destructing messages.
What are the system requirements for the desktop app?+
The Windows app runs on 64-bit Windows 10 and 11 and needs about 100 MB of free space. The macOS app supports macOS 10.13 and later on both Intel and Apple silicon Macs.
Can I use Telegram on multiple devices at the same time?+
Yes. Telegram is cloud-based, so you can stay logged in on your phone, desktop and the web simultaneously. Your chats, media and files stay perfectly in sync across every device.
How do I install the Telegram APK on Android?+
Download the APK from the download page, then open the file. If prompted, allow installation from your browser or file manager, tap 'Install', and open Telegram once it finishes. You can also get Telegram from Google Play.
Do I need a phone number to sign up for Telegram?+
A phone number is required to create an account and verify it with a code. After signing up you can set a public username so people can contact you without sharing your phone number.
How can I recover my Telegram account or messages?+
Because cloud chats are stored securely on Telegram's servers, simply signing in again on any device restores your chats and media. If you enabled two-step verification, keep your password and recovery email safe.
How large are the files I can send on Telegram?+
You can send documents, photos and videos up to 2 GB per file, without losing quality. Media is stored in the cloud, so it does not take up space on your device.
