About URL Encoder / Decoder

URL encoding, also known as Percent-encoding, is a mechanism used for encoding information in a Uniform Resource Identifier (URI) under certain circumstances.

The characters allowed in a URI are either reserved or unreserved (or a percent character as part of a percent-encoding). Reserved characters are those characters that sometimes have special meaning. For example, forward slash characters are used to separate different parts of a URL (or more generally, a URI).

URL Encode and Decode Tool

Use our free online tool from above to either encode or decode a string of text.
For worldwide interoperability, URIs have to be encoded uniformly. To map the wide range of characters used worldwide into the 60 or so allowed characters in a URI, a two-step process is used:

• Convert the character string into a sequence of bytes using the UTF-8 encoding;
• Convert each byte that is not an ASCII letter or digit to %HH, where HH is the hexadecimal value of the byte

For example, the string: François ,would be encoded as: Fran%C3%A7ois
