URL encoding (also known as percent-encoding) converts characters into a format that can be safely transmitted over the Internet.
Characters that are not allowed in URLs (spaces, special characters, non-ASCII) are replaced with a % followed by their hexadecimal value.
For example: hello world becomes hello%20world
Query parameters — encode values before appending to URLs.
API debugging — decode encoded URLs from logs or network traces.
