URL Encoder & Decoder

This tool helps you encode URLs to ensure they're safely transmitted over the internet, and decode URL-encoded text back to its original form.

Standard: encodeURI/decodeURI (preserves valid URL characters)
Component: encodeURIComponent/decodeURIComponent (encodes all special characters)
What is URL Encoding?

URL encoding converts characters that are not allowed in a URL into character-entity equivalents. For example, spaces are converted to %20, question marks to %3F, and so on.

URL encoding is used for:

  • Ensuring URLs are properly formatted for transmission over the Internet
  • Encoding form data when sending it to a server
  • Handling special characters in URLs and query parameters
  • Preventing injection attacks by properly encoding user input
