SEYFR

SEYFR (Send Your Files Right) is a free, ad-free cross-platform file transfer app for sending files and entire folders between Windows, macOS, Linux, Android, and iPhone.

Unlike cloud storage or messaging apps, SEYFR does not upload your files to a server, compress your media, require an account, or force both devices to be on the same Wi-Fi. It creates a secure, encrypted peer-to-peer connection using direct hole-punching, so files travel straight from sender to receiver — even across different networks.

SEYFR has no artificial file size or speed limits, keeps photos and videos in their original quality, and includes a built-in Folder Jail sandbox that prevents the app from accessing files outside its designated transfer folder.

Built for everyone — whether you're moving Xbox clips to your phone, sending large videos from Android to Mac, transferring Steam Deck saves, sharing Quest recordings, delivering files to clients, exchanging lecture materials, collaborating with teammates, or simply sending files between your own devices without relying on cloud storage.
