Both WhatsApp and Telegram are leaders in the messaging app market, each with its own loyal user base and unique features. Here's a breakdown of key differences between the two:



1. Security



WhatsApp: End-to-end encryption by default for all messages. However, backups on Google Drive or iCloud may not be encrypted depending on user settings.



Telegram: End-to-end encryption is only available in "Secret Chats." Regular chats are stored in the cloud with transport encryption.




2. Features



WhatsApp: Offers voice and video calls in groups, temporary status updates (similar to Stories), and payments in some countries.



Telegram: Supports groups of up to 200,000 members, public/private channels, bots for automation, and unlimited cloud storage for media.




3. Data Storage



WhatsApp: Consumes device storage as the entire message history is stored locally.



Telegram: Uses cloud storage, allowing messages to be accessed from different devices without taking up much space.




4. Customization and Usability



WhatsApp: Simple interface with fewer customization options.



Telegram: More customization options, including themes, icons, and notifications.




5. Popularity and Usage



WhatsApp: More popular in regions like Latin America, Europe, and India, widely used for both personal and professional communication.



Telegram: Grown rapidly, especially in tech-savvy communities, due to its flexibility and support for large groups and channels.
