The guide
URL Encoding (Percent-Encoding)
URL encoding converts characters into a format that can be transmitted over the Internet. Characters like spaces become %20 and slashes become %2F to ensure the URL is valid.
URL Encoding Explained
URLs can only contain a limited set of characters (ASCII alphanumeric). Special characters like spaces, question marks, and ampersands must be encoded so they don’t break the URL structure.
- Space ->
%20 - / ->
%2F - ? ->
%3F
This tool uses the JavaScript encodeURIComponent function for reliable standard compliance.
