URL Encoder/Decoder

URL encoding converts characters into a format that can be transmitted over the Internet. Use the form below to Encode or Decode URL.

Paste your URL string in the text box below and click Encode or Decode.

Some characters cannot be part of a URL (for example, the space) and some other characters have a special meaning in a URL: for example, the character # can be used to further specify a subsection (or fragment) of a document; the character = is used to separate a name from a value. A query string may need to be converted to satisfy these constraints. This can be done using a schema known as URL encoding.

In particular, encoding the query string uses the following rules:

  • Letters (A-Z and a-z), numbers (0-9) and the characters '.','-','~' and '_' are left as-is
  • SPACE is encoded as '+' or %20
  • All other characters are encoded as %FF hex representation with any non-ASCII characters first encoded as UTF-8 (or other specified encoding)

The octet corresponding to the tilde ("~") character is often encoded as "%7E" by older URI processing implementations; the "%7E" can be replaced by"~" without changing its interpretation. Source [Wikipedia]
