About this tool

At the core of the web is the Hyper Text Transport Protocol (HTTP), which defines the way web browsers request content from web servers. Content is addressed using a Uniform Resource Locator (URL), which defines a syntax that can easily be parsed.

However, sometimes you need to put additional information in a URL that might be confused for other parts of the syntax. In those cases, you need to use special escape sequences for those characters, which is called URL encoding.

URL encoding simply replaces an character with a the following sequence: %XX. XX is replaced with the ASCII index of that character. For instance, the tilde character is URL encoded as %7E.

Use the form provided enter text to URL encoded or decoded.
