Pair two devices in the browser with a QR code, then move files straight between them. No account, no cloud upload, nothing to install.
Free to start. Pro is $14.99, paid once.
That drawer phone has 64 GB you're not using. SpareDisk lets two of your devices talk to each other directly.
Transfers go device to device. We never store your files, and there's no upload limit set by a server.
No sign-up, no email, no password. Open the page on both devices and pair.
iPhone, Android, Mac, Windows, Linux. If it has a modern browser, it can pair.
Choose "Show QR" on the first device. It displays a pairing code.
Scan the QR with the second device. It shows a short code. Type that code back into the first device.
Drag, tap, or paste. Files move directly between the two devices.
Your first transfer is free. Pro adds the tools for people who move a lot of files.
Launch offer: $9.99 for early customers.
No. Files travel directly between your two devices over an encrypted WebRTC connection. SpareDisk doesn't receive or store them.
Not required. Pairing uses a QR code and a typed code, so no server has to introduce the devices. Some strict networks block direct connections, and in that case a transfer may not connect.
No. SpareDisk runs in the browser. You can add it to your home screen as an app if you want.
The transfer stops, since the page is the connection. Pro can retry and resume where your browser allows it.
No. It's a single payment of $14.99. There is no yearly fee.
Yes. WebRTC data channels are encrypted in transit using DTLS.
Open SpareDisk on two devices and send your first file.
