BIShare is file transfer software that enables secure sharing across iPhone, Android, Windows, Mac, and Linux. The platform offers two transfer methods: direct device-to-device transfers on the same Wi-Fi network with unlimited file sizes and end-to-end encryption, or encrypted links for transfers up to 100 GB when devices are on different networks. Link-based transfers expire after 24 hours, and recipients can access files via browser without installing the software or creating accounts. BIShare requires no account setup, allowing instant use upon installation. Recipients can access files using links, QR codes, or six-character codes. The Rooms feature supports group sharing via short room codes, enabling simultaneous downloads. Native applications ensure a consistent experience across platforms. QR code scanning simplifies file access by allowing recipients to point a camera at the code to initiate downloads.
