HTML URL Encoding Reference
URL - Uniform Resource Locator
Web browsers request pages from web servers by using a URL.
The URL is the address of a web page, like: https://www.w3schools.com.
URL Encoding (Percent Encoding)
URL encoding converts characters into a format that can be transmitted over the Internet.
URLs can only be sent over the Internet using the ASCII character-set.
Since URLs often contain characters outside the ASCII set, the URL has to be converted into a valid ASCII format.
URL encoding replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits.
URLs cannot contain spaces. URL encoding normally replaces a space with a plus (+) sign or with %20.
Try It Yourself
If you click the "Submit" button below, the browser will URL encode the input before it is sent to the server. A page at the server will display the received input.
Try some other input and click Submit again.
URL Encoding Functions
In JavaScript, PHP, and ASP there are functions that can be used to URL encode a string.
PHP has the rawurlencode() function, and ASP has the Server.URLEncode() function.
In JavaScript you can use the encodeURIComponent() function.
Click the "URL Encode" button to see how the JavaScript function encodes the text.
Note: The JavaScript function encodes space as %20.

ASCII Encoding Reference
Your browser will encode input, according to the character-set used in your page.
The default character-set in HTML5 is UTF-8.

Control characters have nothing to do inside a URL.
