Understanding URL Encoding

🔤 What is URL Encoding?

URL encoding converts characters into a format that can be transmitted over the Internet. Special characters are replaced with "%" followed by two hexadecimal digits.

Example:

"Hello World" → "Hello%20World"

"a=b&c=d" → "a%3Db%26c%3Dd"

🎯 When to Use

URL encoding is essential when passing data through URLs, form submissions, or API calls. It ensures special characters don't break your links.
