A cable-free way to move files between your own devices
Instead of connecting a phone to a computer with a USB cable or emailing yourself a file, sending it through this chat and opening WhatsApp on the other device gets it there just as fast.
It behaves like any other chat, with the same limits
Large files may still be subject to the app's normal per-file size limit, and very large media can eventually expire from device storage the same way it would in a regular conversation, so treat it as a convenient shortcut rather than permanent cloud storage.
Frequently Asked Questions
Can anyone else see this chat?
No -- it's visible only to your own account, on any device logged into it, and no other contact can see or join it.
I don't see "Message Yourself" in my contact list -- what do I do?
Start a new chat and search your own name or number; on some app versions it also appears automatically at the top of your contacts once you've used it once.
