HTML URL Encode
URL encoding ensures that special characters in URLs are transmitted correctly over the internet. Spaces, punctuation, and non-ASCII characters must be encoded into a format that browsers and servers understand. Common encodings include %20 for spaces and %3A for colons.
Key Topics
Why Encode URLs?
URLs must use certain allowed characters only. Encoding turns disallowed characters into a percent (%) followed by two hex digits, ensuring safe and valid URLs.
Common Encodings
Examples: Space = %20, : = %3A, / = %2F
URL Encode Example
This example shows an encoded URL. A full code sample is provided below.
<p>Encoded URL: https://www.example.com/search?q=hello%20world</p>Explanation: The space in "hello world" becomes %20, ensuring the URL is valid and interpreted correctly by the server.
