About URL Encoding/Decoding

What is URL Encoding?

URL encoding converts special characters in URLs to a format that can be transmitted over the Internet. It replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits representing the character's UTF-8 encoding.

Two Types of URL Encoding

  • encodeURI: For encoding a complete URL, preserves characters like :, /, &, =
  • encodeURIComponent: For encoding URL components (like query parameters), encodes characters like /, &, :, =

Common Use Cases

  • Making URLs safe for transmission in HTTP requests
  • Encoding form data in query parameters
  • Ensuring special characters are properly represented in URLs
  • Creating valid URLs from user input containing spaces or special characters
  • Handling internationalized domain names and paths
