URL Encode / Decode

Percent-encode or decode URLs and query strings.

How to use the URL encoder

  1. Choose Encode or Decode.
  2. Pick the scope: Component for a single query value or path segment, Full URL for a whole address.
  3. Paste your text into Input; the Output updates as you type.
  4. When the input is a complete URL, its parts and decoded query parameters are listed below the tool.

Example

As a component, hello world & café encodes to hello%20world%20%26%20caf%C3%A9: the space, the ampersand and the accented letter are all escaped. As a full URL,https://example.com/search?q=hello world&lang=vi becomeshttps://example.com/search?q=hello%20world&lang=vi, keeping ? and &so the address still works.

Frequently asked questions

Component or full URL?

Component (encodeURIComponent) encodes every reserved character, including/ ? & = #. Full URL (encodeURI) keeps those characters and only encodes spaces, non-ASCII letters and other unsafe characters.

Why does + become a space?

HTML forms send spaces as + in query strings. Keep Decode + as space on for form data and turn it off when a literal plus sign matters.

Is my URL sent anywhere?

No. Encoding and decoding run entirely in your browser.
