Extensions vs a desktop app
There are Chrome extensions that add an anti-delete feature to web.whatsapp.com. MsgSaver is a Windows app that runs WhatsApp Web in its own window. Both work the same basic way: they see messages as WhatsApp Web loads them, keep a copy, and show it if the message is deleted.
| Browser extension | MsgSaver | |
|---|---|---|
| Where it runs | Inside your browser, on WhatsApp Web | Its own app, in the Windows tray |
| Needs the tab open | Yes, WhatsApp Web has to stay open in the browser | No, it runs in the background after you close the window |
| Instagram too | Usually no | Yes, Instagram direct messages |
| Where saved messages go | Depends on the extension. Some sync to their own server | Only your PC, encrypted with your Windows account |
| Permissions | Can read every page the extension is allowed on | Only the WhatsApp and Instagram windows inside the app |
| Price | Many are free with paid upgrades | Free |
What to check before you install any of them
- Where do your messages go? The tool reads your private chats. Look for a clear answer on whether anything leaves your PC.
- Who makes it? A real contact and a privacy policy are the minimum.
- Does it say what it can't do? Anything that claims to recover old deleted messages is not being straight with you.
- Does it still work? WhatsApp Web changes often. Check that it was updated recently.
Setting up MsgSaver for WhatsApp Web
- Download MsgSaver and install it. Windows may show a warning the first time because the installer isn't signed yet. Click More info, then Run anyway.
- Click Connect next to WhatsApp. A WhatsApp Web window opens.
- On your phone, open WhatsApp, go to Linked devices, and scan the QR code.
- Close the window. MsgSaver keeps running in the tray.
From then on, if someone deletes a message for everyone, it shows up in MsgSaver with the original text, photo, video or voice note. If you turn on Start with Windows, it's running before you open any chat.
Limits that apply to every tool
- Nothing can show messages deleted before it was running.
- View-once photos and videos are never saved by MsgSaver.
- Your PC has to be on to catch the text. If it was off, MsgSaver still tells you who deleted something and when, once it starts again.
