Encode and decode URLs
Built & maintained by Pappu Venkata Subbi Reddy, founder of Clacify
Clacify's URL Encoder converts special characters in URLs and query parameters to percent-encoded format (e.g. spaces become %20, & becomes %26) making them safe for use in HTTP requests. The decoder reverses this — converting %XX sequences back to their original characters. Essential for API development, building query strings, and debugging URL-related issues in web applications.
URLs can only contain a limited set of ASCII characters. Special characters like spaces, &, =, ?, #, and non-ASCII characters (like Indian language text or emoji) must be percent-encoded to be valid in a URL. For example, a space becomes %20, ₹ becomes %E2%82%B9, and & becomes %26 when used as a literal character.
URL encoding (percent encoding) makes individual characters safe for URLs by replacing them with %XX sequences. Base64 encodes entire binary data as a printable ASCII string. URL encoding is used in query parameters; Base64 is used for transmitting binary data (images, files) as text.
