How to encode (and decode) in URL format (URLEncode)

This page encodes and decodes a text string using URL encoding. URL encoding is used when a text string is placed in a URL (for example, to pass variables between two web pages or to send data to a server) so that it is not confused with the URL itself.

URLEncode encoding

Enter the string and press "URLEncode" to encode it or "URLDecode" to decode it.

What is URLEncode?

URLEncode is an encoding method used to turn arbitrary data into a string of characters that is safe to transmit over the internet. It is commonly used in web applications to encode data, such as URL parameters, so that it can be safely transmitted over the web.

The URLEncode function replaces unsafe characters (such as spaces or special characters) with specific hexadecimal codes that browsers and web servers can interpret correctly. For example, a space becomes + (or %20), and other special characters are replaced by similar sequences.

This process helps avoid problems caused by the misinterpretation of special characters, which can lead to errors or malfunctions in web applications. A string encoded with URLEncode is decoded with the URLDecode function.
