The URLEncode and URLDecode Page

This web page encodes or decodes a string using URL Encoding. URL Encoding is used when placing text in a query string to avoid it being confused with the URL itself. It is normally used when the browser sends form data to a web server.

URL Encoding replaces “unsafe” characters with ‘%’ followed by their hex equivalent. Characters which need not be escaped are defined in RFC3986 (which replaced RFC2396). They are the 7-bit ASCII alphanumerics and the characters “-._~”. Unicode characters and 8-bit ASCII characters are normally first encoded using UTF-8, as defined in RFC2279.

RFC2396 mode (no Unicode or UTF8, space encoded as ‘+’)
