Quick Guide

Why URL Percent Encoding is Necessary

URLs can only be sent over the Internet using the ASCII character-set. If a URL contains characters outside this set, such as spaces or special symbols (?, &, =), they must be converted into a valid ASCII format. This is known as URL Encoding or Percent-encoding.

Our URL Encoder ensures your query string parameters and API endpoints are safely transmitted without breaking the URL structure, and decodes messy URLs back into readable text.

  • •Encode text strings to safe URL percent-encoded formats.
  • •Decode percent-encoded URLs back to plain text.

  3. 3Select 'Decode' to translate % escapes back to readable text.
  4. 4Copy the output for use in your API requests or HTML links.

Common Encoding Errors

  • •A space is encoded as '%20' or a plus sign '+'.
  • •Do not encode an entire URL (like https://), only encode the query parameters, otherwise the browser won't recognize the protocol.
  • •Ampersands (&) in query parameters must be encoded as '%26' if they are part of the value.
