What is WiFi Transfer and how does it work?

WiFi Transfer — is an application that creates a local server on one device (for example, a smartphone) and allows other devices on the same Wi-Fi network to connect to it via a browser or special software. Files are transferred directly via the protocol. HTTP or FTP, bypassing cloud storage. This means:

• 📶 No internet dependence — it is enough that both devices are connected to the same router (or one of them distributes the network).
• 🚀 High speed — in a local network, transmission occurs at a speed of up to 50–100 Mbps (depending on the Wi-Fi standard).
• 🔒 Privacy - files are not uploaded to third-party servers (unlike Google Drive or Dropbox).
• 📱 Cross-platform — works between Android, iOS, Windows And macOS.

Technically, the program uses two main mechanisms:

1. Web interface: a mini-server is launched on the phone, which can be connected to from a computer through a browser at an address like http://192.168.1.100:8080.
