URL Encode / Decode

What is Url Encoder?

The URL Encoder & Decoder on AiTechWorlds converts text to and from percent-encoded URL format instantly. URLs can only contain a limited set of characters; special characters like spaces, ampersands, equals signs, and non-ASCII characters must be percent-encoded (e.g., space becomes %20, & becomes %26). This tool encodes any string to its URL-safe percent-encoded form and decodes percent-encoded strings back to readable text. It is essential for constructing query strings, embedding URLs within URLs, passing special characters in API parameters, and debugging URL parsing issues. Both encodeURIComponent and encodeURI behaviors are available. All processing runs in your browser — your URLs and query data are never uploaded to any server. AiTechWorlds provides this utility for developers who work with APIs, query parameters, and URL construction daily.
