Encrypted, peer to peer, file transfer and sharing


Transmitic is an encrypted, p2p, file transfer and sharing program, for Windows, macOS, and Linux.

Devices connect directly to each other. There is no third party server or file size limits.

The goal is to make transferring files and folders as easy as possible.
If you have ever thought I just want to send these files directly from this computer to another, Transmitic will help.


How it Works

  1. Users exchange Public IDs that Transmitic automatically generates.
  2. Add users' Public IDs and IPs that you want to share with.
  3. Add files or folders you want to share, and which users you want to share with.
  4. Turn sharing on! Users can choose which files they want to download directly from your device.
  5. View all files that are shared with you, and download directly from the other user's device.
  6. Connections are encrypted with AES256-GCM.
  7. Users behind NATs and firewalls can use the "Reverse Connection" feature to still share with users that do not have networking limitations.
