WhatsApp and Telegram look alike on the surface: chats, groups, voice notes, calls. Underneath, they’re built on different ideas. WhatsApp is designed around private conversations with people you know. Telegram is designed around the cloud and large communities. Which is “better” depends on which of those you need.
Short answer: use WhatsApp for private chats with family, friends and colleagues. Use Telegram for big communities, channels you follow, and sending large files across devices. Many people end up using both.
Side by side
| Telegram | ||
|---|---|---|
| End-to-end encryption | All chats and calls, by default | Only in Secret Chats (one-to-one, turned on manually) |
| Where chats are stored | On your devices | On Telegram’s servers (cloud) |
| Group size | Up to 1,024 members | Up to 200,000 members |
| Channels | Yes (Updates tab) | Yes, a core feature |
| File size limit | 2 GB | 2 GB (4 GB with Premium) |
| Use on several devices | Phone + up to 4 linked devices | Any number of devices |
| Hide your phone number | Usernames rolling out since 2026 | Usernames for years |
| Backups | Google Drive or iCloud, you manage it | Not needed, everything syncs from the cloud |
| Bots and automation | Mainly for businesses | Open to everyone |
Privacy: the biggest difference
On WhatsApp, every personal chat and call is end-to-end encrypted by default. Only you and the person you’re talking to can read the messages. Not WhatsApp, not Meta.
On Telegram, normal chats and all groups are cloud chats. They’re encrypted between your phone and Telegram’s servers, but Telegram itself can technically access them. End-to-end encryption exists only in Secret Chats, which you have to start manually, which work only for one-to-one conversations, and which stay on the device where you started them.
If privacy of personal conversations matters to you, this point decides it in WhatsApp’s favour. It’s also worth knowing that WhatsApp is owned by Meta, which collects metadata such as who you message and when, even though it can’t read the messages.
Groups, channels and communities: Telegram wins
A WhatsApp group tops out at 1,024 people. A Telegram group can hold 200,000, and a Telegram channel can have unlimited subscribers. Telegram’s tools for large groups, like admin permissions, slow mode, topics and bots, are more mature too.
That’s why tech news, course announcements, job posts and hobby communities so often live on Telegram. WhatsApp has added Channels and Communities, but for a big audience, Telegram still does it better.
Files and multiple devices: Telegram is more flexible
Because Telegram stores everything in the cloud, you can log in on a new laptop and every chat and file is just there, with no QR scan from your phone and no backup to restore. That also makes it a handy personal file store: send something to Saved Messages on your phone and open it on your computer.
WhatsApp has caught up a lot. Linked devices work even when your phone is offline, and you can use WhatsApp in the browser without installing anything (see our WhatsApp Web vs desktop app comparison). But your chat history still depends on backups you manage yourself.
Which one do the people you talk to use?
This matters more than any feature. In Bangladesh, as in much of the world, WhatsApp is where family, friends and most clients already are. A messaging app is only useful if the other person has it, and that alone keeps WhatsApp as most people’s main app.
Ads
Neither shows ads inside your private chats. WhatsApp began showing ads in its Updates tab (where Status and Channels live) in 2025. Telegram shows sponsored messages in large public channels, and offers a paid Premium plan that removes them and adds extras.
The verdict
| If you mainly want to… | Use |
|---|---|
| Chat privately with family and friends | |
| Follow channels and join large communities | Telegram |
| Send big files between your own devices | Telegram |
| Make sure messages are end-to-end encrypted without thinking about it | |
| Reach the people you already know |
The short version
WhatsApp encrypts every personal chat by default and is where most of your contacts already are, so it’s the better choice for private conversations. Telegram’s cloud design makes it better for large groups, channels and moving files between devices, but its normal chats aren’t end-to-end encrypted. There’s no rule against using both, and most people get the best of each that way. If you do decide to leave WhatsApp completely, read what deleting your WhatsApp account removes before you do it. And if you’re staying, WhatsApp is rolling out a built-in way to schedule messages.
