URL Encoder
100% Client-SideURL Encoder helps you encode or decode URL-safe text so reserved characters can travel correctly in query strings or paths. It is meant for quick development work such as building query parameters, debugging redirect URLs, and checking percent-encoded values.
Component mode matches encodeURIComponent (spaces become %20). Form mode matches application/x-www-form-urlencoded (spaces become +). Use component mode for a single query value or path segment, not a whole URL.
