Your devices have to be connected to the same Wi-Fi network, otherwise the file transfer service will return an error.
Since our file-sharing service is always hosted from an iOS device (either iPhone or iPad), Android-to-Android and similar transfers are currently not supported.
Our service is free and allows for unlimited file transfers between devices.
Your second device is likely either offline or connected to a different Wi-Fi network. Please also note that we don't currently support hotspot networks, so even if your devices are connected to the same hotspot, the service still won't work due to technical limitations.
Simply point the camera of your device toward the QR code and open the generated link.
To use our free iOS file transfer, your iPhone or iPad device should support iOS 15.0 or later and your PDF Extra app should be on version 4.2 or above. Our file transfer service is compatible with all recent Android, Windows, macOS, and iOS devices.
