A vless:// or trojan:// link packs every connection parameter into one string. This tool breaks it into readable fields and generates a QR code to move the node to your phone. The data never leaves your browser.
Server and port are where to connect; UUID or password is your access key (never share it); SNI is the domain named in the TLS handshake; pbk and sid are Reality parameters; type is the transport (tcp, ws, grpc). The background is in what is VLESS.
iPhone and Android clients (Streisand, v2rayNG, Hiddify, Shadowrocket) import a node by scanning. Point the app's camera at the code and the node appears in the list without copying anything.
Parsing happens entirely in your browser: the link is not sent to any server and is not stored. Secret fields stay hidden until you press "show".
In the 404 VPN app the server list is built into your account: sign in and connect, no links or subscriptions. Same protocols: VLESS + Reality and WireGuard.
