WhatsApp vs Signal
On WhatsApp, can send over files, media, contacts, and location details. There’s a 16MB size limit for sending video, images, and voice recordings at 16MB. Transfer size for documents and files is capped at 100MB.
Signal also comes with basic direct messaging features including the option to send media, contacts, and location. File size limits vary depending on what you’re sending. Images are capped at 6MB, while video, audio, and documents are capped at 100MB. Both platforms come with the audio and video call feature.
On WhatsApp, you can add images and videos to your status/story that can be seen by WhatsApp users on your contact list. At the moment, this feature is not available on Signal. But considering Signal is seeing a lot of traction in recent times, we might get this feature on the app in no distant time.
3. Chat Groups
WhatsApp allows a user to create and add as many as 256 participants to a group, Signal on the other hand allows users to add up to 1000 members to a group.
4. Disappearing Messages
WhatsApp and Signal offer the self-destruct message feature (disappearing messages) that lets users customize a sent message to disappear after a certain amount of time (between 5 seconds to 7 days).
5. Privacy and Security
In terms of security, both platforms offer end-to-end encryption. Messages, audio and video chats, and files are protected by end-to-end encryption. So neither WhatsApp nor Signal can eavesdrop on your conversations.
Signal, on the other hand, pays a lot of attention to the privacy of its users. On Signal, there’s the Relay Call feature which allows users to channel all calls through the Signal server to avoid revealing real IP address to contacts.
Also, Signal only stores your phone number and contact details. WhatsApp on the other hand, asks for a lot of data information including Device ID, User ID, phone number, email address, contact information, etc.
When it comes to security and privacy, Signal looks way more secure than WhatsApp.

One thought on “WhatsApp vs Signal: Features Comparison”
To use WhatsApp, you must “sign up.” But you don’t have to sign up with Signal to receiver or send messages, do you? And if you’re sending messages and haven’t become a member, do they NOT NOT encrypt your messages?
The question is what happens to your content on Signal if you use the platform without becoming a member, which is free, by the way….?
