What is URL Encoding (Percent-Encoding)?

URL Encoding (also known as Percent-Encoding) converts characters that have special reserved meanings or are unsafe in a URL into valid ASCII percent sequences (% followed by two hexadecimal digits).

Standardized in RFC 3986, it ensures query parameters, path segments, and form submissions carry spaces, slashes, ampersands, and international characters safely across the web.

For instance, spaces become '%20' (or '+' in query forms), ampersands become '%26', and question marks become '%3F'.

How to Use

  1. Enter or paste the URL or string into the input box.
  2. The percent-encoded URL string is generated automatically in real time.
  3. Click 'Copy' to copy the encoded URL.
  4. Use 'Sample' to quickly test with a sample URL.

FAQ

What is the difference between %20 and + for spaces?
RFC 3986 specifies %20 for URI path and query encoding. The '+' character is a historical convention specifically defined in application/x-www-form-urlencoded query strings.
