When choosing a messenger app, you may wonder “Telegram or Signal?” Both apps are popular for chatting, but they focus on different things. We will compare Telegram vs Signal in detail. We’ll look at features, security, user base, and more, all in simple language. By the end, you’ll know which app fits your needs.
What Are Telegram and Signal?
Telegram and Signal are both chat apps made for instant messaging on phones and computers. Telegram was launched in 2013 by brothers Pavel and Nikolai Durov. It calls itself fast, flexible, and cloud-based. Signal came later (2014) from the Signal Foundation, a non-profit started by Moxie Marlinspike and Brian Acton (WhatsApp’s co-founder). Signal focuses on privacy and security. Both apps are free to download and use. They let you send messages, photos, videos, and make voice or video calls over the internet.
Telegram emphasizes being fast, secure, and private. It was created to protect messages from third parties.
Telegram stores your chats on the cloud, making them available on any device. Signal stores your data only on your device. Telegram’s code is partly closed (only the app code is open-source). Signal’s code, including server and app, is fully open-source. Signal also runs on donations and does not show ads or sell data. Telegram is privately owned and has started adding ads in channels and a paid subscription (Telegram Premium) for extra features.
Platforms and Device Support
Both Telegram vs Signal offer apps for all major platforms. You can use them on Android phones and tablets, iPhones, Windows, macOS, and even Linux. Telegram also has a web version. However, there are some differences in how they work on Android and tablets:
- Telegram on Android: Telegram’s Android app works on phones and tablets. It stays fully in sync across all your devices, including desktop and web. One Telegram account can be logged in on unlimited devices at once.
- Signal on Android: Signal also has Android and iOS apps. But you must link your phone (your “main” device) to use it on a desktop or tablet. Signal allows up to 5 linked devices. It does not have a special tablet app – the phone app must run on tablets. Signal can work without Google Play Services (through its APK).
Both apps run on smartphones. You install them on your Android or iPhone and verify with a phone number.
Both apps require a phone number to sign up. Telegram lets you choose a username too, so you can chat without giving out your number. Signal recently added usernames as well (so you can hide your number). On Android, both apps perform well. Telegram also supports background syncing and a light app size. Signal on Android is very secure but needs your phone’s key for decryption.
Chat Features and Messaging
Telegram and Signal have most standard chat features, but Telegram is more feature-rich. In both apps, you can:
- Send one-on-one text messages.
- Do group chats.
- Send photos, videos, voice notes, and files.
- Make voice calls and video calls.
- Use emojis and stickers.
- Set messages or media to disappear (self-destruct).
However, Telegram vs Signal differs in scope:
- Group Chats: Telegram allows huge groups (up to 200,000 people). You can even create “Supergroups” with advanced admin tools. Signal’s group chats are capped at 1,000 members.
- Channels and Broadcasts: Telegram has public channels where admins broadcast messages to unlimited subscribers. Signal has no channel feature. It only has private groups or one-to-one chats.
- Bots & Automation: Telegram supports bots (automated chat helpers) for games, weather, news, etc. Signal has no bots.
- File Sharing: Telegram stands out: you can send files up to 2 GB (or even 4 GB if you pay for Premium). Signal limits file transfers to 100 MB (and 25 MB for animated GIFs) which is fine for most chats but won’t work for large videos.
- Customization: Telegram lets you change themes, use many sticker packs (including animated stickers), and organize chats into folders. You can edit sent messages too. Signal’s customization is simpler: you have standard emojis and stickers, and a dark/light theme. It does not let you create chat folders or buy sticker packs.
In short, Telegram or Signal, which is better? If you want advanced features, channels, big groups, and lots of media, Telegram wins. If you want a basic chat with top privacy, Signal wins.
Encryption and Security
Security is a key difference between Signal vs Telegram. Both apps encrypt your messages, but in different ways:
- Signal Encryption: Signal uses the strong Signal Protocol for end-to-end encryption (E2EE) by default on all chats, calls, and media. This means only you and the person you’re talking to can read the messages. Not even Signal’s servers can decrypt them. Signal is fully open-source (anyone can inspect the code) and regularly audited by experts. Signal also pioneered features like “sealed sender” (which hides who is sending a message) and now provides options like “view once” media, disappearing messages, and strong authentication (PIN and biometric locks).
- Telegram Encryption: Telegram uses its own protocol (MTProto). Regular chats on Telegram are not E2EE by default. They are encrypted between you and Telegram’s cloud servers. Telegram can read or hand over your messages if needed. You must turn on “Secret Chat” mode to get E2EE, and secret chats work only on one device (no cloud sync). Voice and video calls on Telegram are E2EE by default, but group calls and channels are not. Telegram only open-sources its app code (not its server code). This means outsiders can’t fully audit Telegram’s server security.
Signal encrypts everything by default and is open-source. Telegram requires you to use “Secret Chats” for true end-to-end encryption. In normal mode, Telegram decrypts messages on its servers before sending them.
As a result, security experts consider Signal more private. Signal collects almost no data about you (only your phone number and optional profile). It does not log your IP address or contacts. Telegram logs more: your phone number, IP address, contacts (if allowed), and stores all your non-secret chats on its servers. Also, Signal’s server and app code are public, so bugs are found and fixed faster. Telegram has never undergone a full security audit, despite a bug bounty program.
That said, both apps are generally safer than regular SMS or many other messengers. Signal vs Telegram security tips: if privacy is your top concern, Signal is the clear winner. Telegram still has good encryption for secret chats, but most users leave that off. Telegram’s founder is outspoken about privacy, but technical protections are weaker by default.
Data Collection and Privacy
Beyond encryption, how apps handle your data is important:
- Signal’s Policy: Signal collects almost nothing. It only keeps your phone number and the date you registered. It does not log IP addresses, contact lists, profile info, or chat messages. Even profile pictures and group membership are hidden on servers. Signal is run by a non-profit and has no ads or tracking.
- Telegram’s Policy: Telegram keeps more metadata. It stores your phone number, basic profile info, IP address, and device info. Telegram also stores all your regular chats in the cloud (to sync across devices). While it claims user data is not sold, Telegram has complied with court orders to hand over user data in the past.
In plain terms, Signal’s privacy model is “we don’t have your data to give away.” Telegram’s is “we store things in the cloud for convenience, and we do have some info.” This makes Signal the safer choice if you fear surveillance. Telegram is still fairly good, but it’s less private in practice.
Ease of Use and Features
Both Telegram and Signal are easy to use, but Telegram offers more options:
- User Interface: Both apps look like typical chat apps. Telegram’s interface is colorful and full-featured. It has many sticker packs, themes, and even hidden games in chats. Signal’s interface is more plain and minimal, focusing on chatting only.
- Synchronization: With Telegram you can access all your chats from anywhere at once. Your messages sync instantly on any device because they’re stored in the cloud. With Signal, chats sync only when linked devices are connected. You can read/send from up to 5 devices, but new messages go to your phone first.
- Extras: Telegram has animated stickers, polls, quizzes, bots, and a built-in photo editor. It even has a secret code-search feature and chat folders. Signal has message reactions, disappearing messages, group polls, and media editing, but no bots or channels yet. In late 2024 Signal introduced call links, so you can share a link for others to join a call without a group chat. Telegram has had rich call features like screen-sharing.
Both are friendly apps. If you just want to chat, either works. If you like extra bells and whistles (bots, channels, big groups), Telegram has them. Signal keeps it simple and private.
Popularity and Users
Telegram and Signal have very different user bases. Telegram vs Signal users is all about scale:
- Telegram: As of early 2025, Telegram boasts over 1 billion monthly active users worldwide. It is extremely popular in many countries (Russia, Iran, India, parts of Europe). It was growing 50-70 million users per year, reaching 1B in 2025.
- Signal: Signal’s user base is much smaller. It had around 70 million monthly active users by early 2025. It saw a big spike in early 2021 but didn’t keep pace with Telegram. In the U.S., Signal got popular among privacy-conscious people, but still far fewer users.
Simply put, more of your friends and family are on Telegram than on Signal. Many sources note that Telegram’s active users (~800M in 2024) easily outnumber Signal’s (tens of millions). If you rely on chats or channels, Telegram’s huge audience is a plus. If not many people you know use Signal, it may be hard to convince them to switch.
Nevertheless, both communities have grown. Journalists, activists, and tech fans are often on Signal for privacy. Telegram is used by communities, companies, and even public news channels. “Telegram vs Signal Android” or “Telegram vs Signal iPhone” often shows both apps topping download charts during privacy scares. But Signal’s growth is slower.
Cost, Ads, and Premium Features
Both Telegram and Signal are free to use. But they handle money differently:
- Telegram: Free to download and use. To make money, Telegram added optional ads in public channels and a Premium subscription (currently about $5/month). Telegram Premium users get extra features: higher limits (4 GB file uploads), unique stickers, faster speeds, and more. Telegram does not charge for the basic service. It also offers paid messages in channels (sponsored posts) as a way to generate revenue.
- Signal: 100% free, no paid tier. Signal never sells ads or collects data to profit. It’s funded entirely by donations and grants (including a $50M donation from Brian Acton). You can even donate to support Signal, as shown in the app. Because Signal doesn’t seek profit, there are no ads at all.
Signal relies on user donations to fund development and hosting. The app shows how you can contribute (“Signal Sustainers”) rather than showing ads.
In practice, both offer solid free service. Only Telegram has an option to pay for extras. Otherwise, neither app requires any payment, and neither pushes ads in chats (except Telegram’s own channel ads).
Security Comparison: Signal vs Telegram
When focusing on Signal vs Telegram security, remember the key points:
- Encryption: Signal secures all your chats and calls end-to-end. Telegram only secures secret chats end-to-end; normal chats are encrypted but accessible by Telegram.
- Data Use: Signal collects minimal user data; Telegram collects more metadata (IP, contact list, etc.).
- Open Source: Signal’s entire platform is open-source, enabling outside audits. Telegram’s server code is closed, so it can’t be fully audited.
- Incidents: Both have had security incidents. Signal’s breach in 2022 exposed only ~1,900 phone numbers. Telegram had breaches exposing phone numbers and chat data in 2016 and 2024. Signal fixes issues quickly, whereas Telegram has had repeated attacks (though it still recovered). Signal even built proxy tools to bypass censorship in countries where it’s blocked.
In simple terms, Signal is stronger on security and privacy out of the box, while Telegram offers more features with slightly less privacy. The expression “Signal vs Telegram security” usually means Signal is more secure. But Telegram’s optional secret chat is still encrypted, so it’s not insecure if you use it carefully.
Android Differences
If you use Android, there are a few platform-specific differences in the Telegram vs Signal Android experience:
- App Size: Telegram’s Android app is around 150 MB. Signal’s is about 60 MB. Telegram also has a “Telegram X” lighter client on Android (though now merged).
- Play Store Requirements: Telegram requires a standard Android with Google Play, but also runs via APK if needed. Signal can be installed from Play Store or F-Droid; its “Debug APK” can run without Google services.
- Desktop Linking: On Android, linking Signal to desktop uses a QR code and was slow to sync history until the recent “linked devices” feature. Telegram’s Android app always synced instantly with its Windows/Mac/Web versions.
Overall, “Telegram vs Signal Android” doesn’t imply major functional differences beyond these. Both work smoothly on Android phones.
Which to Use? (Use Cases)
Choosing between Telegram vs Signal depends on your needs:
- Use Telegram if: You want large group chats, public channels, bots, and rich features. Telegram is great for communities, news channels, or sharing media with many people. It works everywhere (even web browser) and is user-friendly. It’s best for communication and entertainment where some privacy is okay.
- Use Signal if: You care most about keeping chats secret and private. Signal is ideal for one-on-one chats or small groups that contain sensitive info. It’s often recommended for journalists, activists, or anyone under surveillance. If your group is small (under 1000 people) and you want strong encryption and minimal data sharing, Signal wins.
- Both: Many people install both. They might use Telegram for casual chats and channels, and Signal for private talks. They are not mutually exclusive.
New Features (2024–2025 Updates)
In 2024–2025, both apps added new capabilities that older comparisons might miss:
- Telegram (Spring–Summer 2025 updates): Introduced Grok, an AI assistant powered by Musk’s xAI, for Premium users. Added digital “Stars” and paid channels for tipping creators. Enhanced Stories (short posts) with clickable links and hashtags to discover content. Now offers end-to-end encrypted group calls for up to 200 participants, with screen sharing and new call interface. These turn Telegram into a more versatile platform with built-in AI and monetization.
- Signal (late 2024): Released call links and improvements: now you can share a link for people to join a call without a group chat, and use features like “raise hand” and emoji reactions during calls. Signal supports group calls up to 50 people. In early 2025, Signal added synchronized start for linked devices: you can now transfer recent chat history (last 45 days) to a newly linked desktop or iPad, all fully end-to-end encrypted.
These updates mean both platforms keep evolving. If you compare Telegram vs Signal in 2025, you have to consider these new features (AI bots vs advanced call tools).
Telegram vs Signal – Conclusion
Deciding between Telegram vs Signal depends on what matters to you. Telegram offers more features and a bigger audience: huge groups, channels, bots, and rich media. Signal offers stronger privacy and security: full end-to-end encryption by default, minimal data collection, and open audits.
If privacy is top priority, choose Signal. If you need versatility and community features, choose Telegram. Both apps are free, easy to use, and far more private than many alternatives. In the end, Telegram vs Signal is not about one being “better” overall, but about which trade-offs suit your needs. Whichever you pick, you’ll get a modern, secure chat app. The best choice depends on your use case and priorities.
