Percent-encode a query value or a whole URL, and decode encoded links back into readable text. Runs locally in your browser.

Everything on this page is processed in your browser. Nothing is uploaded.

What this tool does

URLs may only contain a limited set of characters, so spaces, accents and symbols must be percent-encoded. Choose Query value to escape everything that is unsafe inside a parameter, or Full URL to keep the separators such as slashes, colons and question marks intact.

How to use it

  1. Pick Query value for a single parameter or Full URL for a complete link.
  2. Paste your text and press Encode or Decode.
  3. Copy the encoded or decoded result.

Privacy

This tool runs entirely in your browser. Your input is never uploaded, stored or shared — closing the tab removes it.

Frequently asked questions

What is the difference between the two modes?
Query value escapes reserved characters such as & = ? /, which is what you want inside a parameter. Full URL leaves them alone so the link stays usable.
Why do spaces become %20?
%20 is the percent-encoded form of a space. Some systems use + instead inside query strings; both are widely accepted.
