What Is a URL Encoder/Decoder?

A URL Encoder/Decoder is a tool used to convert special characters in a URL into a format that is universally accepted by web browsers and servers. This is crucial when working with URLs that include spaces, symbols, or reserved characters that could break a link or be misinterpreted by a browser.

URL encoding replaces unsafe ASCII characters with a “%” followed by two hexadecimal digits. For example, a space becomes %20. Decoding reverses the process, turning encoded characters back into human-readable text.
