Send
Encrypted in transit and sent directly between devices. Your file is never uploaded to or stored on a server.
Keep this browser tab open until the transfer is done.
Share Between Devices moves the file straight from your browser to theirs over WebRTC — no server storage, no size cap, no re-encoding. Scan the QR code or share the link, and the transfer starts the moment the other device connects.
Nothing is uploaded first. The file stays on your device until the other side opens your link, and then it streams straight across — which is why there is no upload progress bar and no size limit to worry about. A 5 GB video is the same operation as a 5 KB text file, just longer. Because the file is read from your disk as it goes, keep this tab open and the screen awake until the transfer reports complete.
You can select several files at once and the recipient sees the full list with sizes before anything moves, choosing to accept or skip each one. Files are sent exactly as they are — no recompression, no resizing, no metadata stripping — and both sides compare a checksum at the end so you know it arrived intact. Photos and videos in particular reach the other device at their original quality, which is not true of most messaging apps.
