Encrypt a file in your browser and send it to a nearby device as a short melody. No server/backend, account, pairing, QR code, or app install. Completely private send.
ToneTransfer lets you send a file or message to a nearby device without an account, pairing flow, QR code, or app. The sender encrypts the file in the browser and plays a short melody containing the retrieval code. The receiving browser listens, fetches the encrypted file, and decrypts it automatically. Free and works in modern browsers.
This started with a slightly strange question: if two devices are sitting next to each other, why should sending a file still begin with a login, pairing screen, QR code, or copied link?
ToneTransfer turns the handoff into sound. Choose a file or type a message, let the receiving browser listen, then play a short melody. The sender encrypts the file in the browser, the melody carries a retrieval code, and the receiving browser fetches and decrypts it automatically.
No account. No pairing. No QR code. No app install.
The melody carries the handoff rather than the entire file. But that tiny interaction makes file transfer feel surprisingly physical.
If you only have one device, try the same-device demo. I’d especially love feedback on reliability across browsers, phones, and noisy rooms, along with any use cases this makes you think of.
