About URL Encoding

What is URL 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.

Common Use Cases

  • Encoding URL parameters for API requests
  • Creating shareable links with complex parameters
  • Encoding form data before submission
  • Working with query strings containing special characters
  • Encoding URLs for use in email or social media

URL Encoding Examples

Special Characters

Space ( ) → %20
Question mark (?) → %3F

Equals sign (=) → %3D
Plus sign (+) → %2B

Complex Example

Before: https://example.com/search?query=hello world&category=books&price=$20-$30  After: https://example.com/search%3Fquery%3Dhello%2520world%26category%3Dbooks%26price%3D%252420-%252430
