How to use the URL Encoder

  1. Paste the text or URL you want to encode.
  2. Choose "Component / value" for a query value or path segment, or "Full URL" for a complete address.
  3. Tick "Spaces as +" if the value goes into an HTML form body or a query string that expects form encoding.
  4. Copy or download the encoded result; full URLs are broken down in the URL parser below.

Frequently asked questions

What is URL encoding?

URL encoding (percent-encoding) replaces characters that aren't allowed in a URL with a % followed by two hex digits of their UTF-8 bytes. A space becomes %20 and "é" becomes %C3%A9.

encodeURIComponent vs encodeURI — which should I use?

Use encodeURIComponent ("Component / value") for a single piece such as a query parameter value; it also encodes / ? & = # so they can't break the URL. Use encodeURI ("Full URL") only for a complete URL, because it leaves those structural characters in place.

Should spaces be %20 or +?

Both are common. %20 is valid everywhere in a URL. The + sign means a space only in application/x-www-form-urlencoded data — HTML form submissions and most query strings — so use "Spaces as +" only there.

Which characters are not encoded?

encodeURIComponent leaves letters, digits and - _ . ! ~ * ' ( ) unchanged. RFC 3986 treats ! ' ( ) * as reserved, so tick the RFC 3986 option if a strict API (for example OAuth signatures) requires them encoded too.

Is my data sent anywhere?

No. Encoding runs entirely in your browser; nothing you paste is uploaded or stored.
