    P2Lan Transfer

    P2Lan Transfer

    Make LAN transfers easy, no server needed

    Github: https://github.com/TrongAJTT/p2lan-transfer. You want to transfer file between your devices and view them immediately, but: - Cable transfer: Fast, but the process of navigating and selecting photos on the laptop is unintuitive. - Third-party OTT apps: Inconvenient for sending many files, and photos may lose quality due to compression. - Cloud storage: Convenient and maintains photo quality, but requires the annoying extra step of deleting files afterward. Then, P2Lan Transfer may be a solution that suits you. P2Lan Transfer helps you share files and chat with devices on the same local network without requiring any central server or complex setup. Just run the app on both devices and they can find each other automatically. You can also chat and send media or file with other devices locally (no server needed) and sync clipboard with that chat. 💻 Platform Support: Android, Windows. - Web, Linux, MacOS may available in the future.
