Direct transfer
Both browsers connect over WebRTC and the files stream directly between them
Is there a file size limit?
No — files stream straight from one device to the other, so you're limited only by your connection and the receiver's free disk space
Do both sides need to be online?
Yes — both tabs have to stay open until the transfer finishes
Can fsend see my files?
No — fsend uses end to end encrypted WebRTC data channels. File data never touches our servers
Which browsers work best?
Anything with WebRTC. Chrome, Edge and Opera also ship the File System Access API, so fsend writes straight to disk and can resume interrupted transfers. Firefox and Safari buffer the transfer in memory and save a zip at the end, which caps a transfer at your available RAM.
Can I use it outside the browser?
Yes — fsend is available as a command-line tool. You can find the installation instructions on GitHub.
Is it free?
Yes — free and open source. The code is on GitHub.
