WA Backup - WhatsApp Web Chat Archive

Never lose a WhatsApp conversation again. WA Backup quietly archives the chats you can see in WhatsApp Web — messages, replies, reactions, photos, videos, voice notes and documents — into a private, encrypted archive you control. Why people use it • Messages that arrived while your computer was off are archived the moment WhatsApp Web catches up. • Search and browse years of conversations without scrolling through WhatsApp. • Export any chat as a beautiful HTML transcript, JSON or CSV — with media — in one click. • Keep a copy of important business, family or group conversations. How it works 1. Install the extension and open web.whatsapp.com. 2. WA Backup detects your chats and starts an incremental backup (you can pause, exclude chats, or limit history depth). 3. New messages are archived live while the tab is open. Periodic rescans catch anything missed. 4. Everything is encrypted on your computer with a recovery key that only you hold before anything is uploaded to your private archive. Privacy first • Read-only: the extension never sends messages, never marks anything as read, never modifies WhatsApp. • End-to-end style encryption: chats are encrypted locally (AES-256-GCM). Our servers store only ciphertext and cannot read your conversations. • Local-only mode: without an account, everything stays on your device and can still be exported. • Minimal permissions, no analytics on your chat content. Good to know WhatsApp Web only receives the recent history WhatsApp chooses to sync to linked devices, so older messages may be incomplete. WA Backup is not affiliated with WhatsApp or Meta.
