VMess JSON converter

Decode a vmess:// Base64 payload into its JSON fields, edit them and re-encode.

JSON payload (decoded, for reference)
{
  "v": "2",
  "ps": "",
  "add": "",
  "port": "443",
  "id": "",
  "aid": "0",
  "scy": "auto",
  "net": "tcp",

  "sni": "",
  "alpn": "",
  "fp": ""
}

The payload is the standard Base64 of the JSON object shown above. Everything is encoded and decoded locally in your browser.

How it works

  1. Paste a vmess:// URI — the Base64 JSON is decoded locally.
  2. Edit the JSON fields (address, port, id, net, tls, path…).
  3. A re-encoded vmess:// URI is produced live with a copy button.
Config parser
Paste any mix of proxy URIs and get a per-line breakdown: protocol, address:port, network, security and name.
Config inspector
Inspect a single configuration URI field by field: protocol, transport, TLS, SNI, path and more.
Base64 encode / decode
Encode text to Base64 or decode subscription payloads, with padding- and URL-safe-tolerance.
Config validator
Check a list of URIs for syntax errors and get factual notes about missing SNI or insecure flags.
