URL Encoding Guide

URL encoding converts characters that are not allowed in URLs (like spaces, punctuation, and foreign characters) into a format that can be transmitted over the Internet.

  • Encode Converts normal text into percent-encoded format. Example: `hello world` becomes `hello%20world`.
  • Decode Converts the percent-encoded string back into a human-readable format.
  • Standard This tool uses the `encodeURIComponent` standard, which is suitable for query parameters and paths.
