Encode URLs and query strings for safe transmission, or decode percent-encoded URLs back to readable text. Parse full URLs into their component parts instantly.
encodeURIComponent encodes everything including /, ?, = and & — use this for query string values. encodeURI preserves URL structure characters for full URL encoding.
Parse any URL into protocol, host, pathname, query parameters and hash fragment. Displays each component separately as structured JSON.
No button clicks needed for basic encoding — results appear as you type. All operations use the browser's built-in URL APIs for maximum accuracy.
URLs and query strings often contain sensitive tokens and parameters. Everything stays in your browser — nothing is sent to any server.
