Encrypted before transport
Transfera protects file data before it travels and pairs sender and receiver through a temporary access key or QR code.
Transfera
The browser encrypts file data for the paired session. When a direct WebRTC connection is available, files move between the two devices over an encrypted peer connection. When direct transfer is unavailable, the fallback relay carries encrypted data rather than a readable file.
Transfera
Transfera avoids permanent public file pages. The receiver joins the temporary session, accepts the transfer, and saves the file on their device.
Transfera
The access key or QR code should be shared only with the intended receiver. Device security and browser integrity still matter, and highly sensitive transfers should use trusted devices and networks.
Common questions
File data is encrypted in the browser before relay fallback transport.
Transfera can use a temporary relay path while keeping the file payload encrypted.
Access keys are intended for temporary transfer sessions, not permanent sharing.
Pair two devices and start an encrypted browser transfer. No account required.
