About URL Encoding

URL encoding, also known as percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI). It converts characters that are not allowed in a URL into a format that can be transmitted over the Internet.

When to Use URL Encoding

  • Sending data in query parameters
  • Embedding URLs in HTML or other markup
  • Transmitting special characters in web addresses
  • API calls with complex data
