About this URL encoder & decoder
URLs may only contain a limited set of characters, so spaces, ampersands, and non-English letters must be percent-encoded (for example, a space becomes %20). This tool encodes text for safe use in URLs and query strings, and decodes percent-encoded URLs back into readable text.
When to use which mode
  • Encoding a value to drop into ?key=value? Use Component.
  • Encoding a full link that already has its structure? Use Whole URL.
  • Reading an encoded link? Use Decode.
Frequently asked questions
What is the difference between “Component” and “Whole URL”?
“Component” (encodeURIComponent) escapes everything that is not safe inside a single value, including &, =, ?, and /. Use it for query-parameter values. “Whole URL” (encodeURI) keeps URL-structure characters intact, so it is for encoding a complete address.
Why does my decoded text show spaces where + used to be?
In query strings, + often means a space. The decoder converts + to a space before decoding, matching how form data is typically encoded.
Is anything uploaded?
No. Encoding and decoding run entirely in your browser.
