WinDrop
AirDrop for Windows. Zero config. Fully encrypted.
Seamless peer-to-peer file sharing over your local network. No setup, no accounts, no cloud — just drop and go.
How It Works
Three steps. That's it.
No installation wizards, no cloud accounts, no network configuration. WinDrop works the moment you launch it.
Discover
WinDrop automatically finds every device on your local network using mDNS — no IP addresses, no pairing codes, no setup.
Powered by Zeroconf DNS-SD
Drop
Drag and drop files or entire folders onto any device card. Multi-file transfers, progress tracking, and speed graphs — all built in.
Files & folders, any size
Done
Files arrive encrypted end-to-end with AES-256-GCM, verified with SHA-256 checksums. Tamper-proof, every time.
Integrity verified automatically
