Signal Desktop as a Linux alternative to WhatsApp Desktop
Updated
Our verdict
Signal Desktop can replace WhatsApp Desktop for users who value end‑to‑end encryption and open‑source software. It works on Linux, Windows, macOS, Android, and iOS, and syncs via QR code with the mobile app. It supports text, voice, and video calls, file transfer, group chats, and self‑destructing messages. If you rely on WhatsApp’s broader ecosystem (e.g., business accounts, stickers, or integration with other apps), Signal may not cover those needs. For privacy‑focused individuals, Signal Desktop is a solid choice.

Opening your WhatsApp Desktop files
WhatsApp Desktop stores chats in an encrypted SQLite database on the local machine. Signal Desktop does not read or import that format. To migrate, you would need to export chats from WhatsApp (via the mobile app’s export feature) and then manually copy media into Signal, but no direct import is available.
Switching from WhatsApp Desktop to Signal Desktop, step by step
- 1. On your phone, open WhatsApp and export the desired chat history to a text or JSON file. 2. Save the exported file to a cloud service or USB drive. 3. Install Signal Desktop on your Linux machine and set it up by scanning the QR code with the Signal mobile app. 4. Manually copy media files into the Signal chat by dragging them into the conversation window. 5. If you want to keep the chat history, note that Signal does not import WhatsApp backups; you will need to re‑create conversations manually.
