This service encodes a string in conformity to RFC 1738 for protecting literal characters from being interpreted as special URL delimiters, and for protecting URLs from being mangled by transmission media with character conversions.
All non-alphanumeric characters (except "-", "_", ".") will be replaced with a percent ("%") sign followed by two hex digits.

Information

If you select "form like" the encoding will behave the same way that posted data from a HTML form is encoded (which is the same way as in "application/x-www-form-urlencoded" media type). This differs from the RFC1738 encoding as it converts "spaces" to plus ("+") signs. Selecting "RFC conform" converts according to RFC1738.
