Free online URL Encoder / Decoder tool — results appear instantly in your browser. No signup required.
Useful for encoding special characters in URLs, query strings, and for debugging percent-encoding issues.
URL Encoder / Decoder converts text into a safe format for use inside web addresses and also reverses the process. Special characters such as spaces, ampersands and non-ASCII letters must be percent-encoded so that browsers and servers interpret them correctly. Developers, SEO specialists and marketers frequently need to encode query parameters, tracking codes or international characters before inserting them into links. The decoder side is equally useful when you receive a long, hard-to-read URL and want to see the original values. Everything runs client-side, so sensitive tokens or private parameters stay on your machine. Paste the text, choose Encode or Decode, and copy the result in one click.
