About URL Encoding

  • URL Encoding converts characters into a format that can be transmitted over the Internet safely.
  • URL Decoding converts encoded URLs back to their original readable format.
  • URLs can only be sent over the Internet using the ASCII character set.
  • Reserved characters like spaces, ampersands, question marks, etc. must be encoded.
  • A space is encoded as %20, an ampersand as %26, and a question mark as %3F.
  • This tool works entirely in your browser - your data never leaves your computer.
