LocalSend is a free, open-source, cross-platform file sharing tool that allows you to share files to nearby devices. The software has an easy to use interface that enables functionality simply and easily. Transferring files is quick and painless. There are no ads or trackers.
LocalSend is available for Windows, macOS, Linux, Android, and iOS. There is even a web-based client. I highly recommend this software.

The transfer happens instantly over your local network.
I'm wondering how javascript is sending LLMNR or similar
