Comment utiliser : URL Decode
- Paste the encoded URL or text — it is decoded as you type.
- Turn on “+ as space” for form-encoded query strings.
- Copy the readable result; query parameters are listed one by one below.
What URL decoding does
URLs can only contain a limited set of characters, so everything else is percent-encoded: a percent sign followed by the byte value in hex. A space becomes %20, “/” becomes %2F and “é” becomes the two UTF-8 bytes %C3%A9. Decoding turns those sequences back into characters.
Plus signs: space or plus?
In HTML form submissions (application/x-www-form-urlencoded) a space is written as “+”, so q=hello+world means “hello world”. In the path of a URL, “+” is a literal plus. Turn on + as space only for query strings and form data.
Decoding twice
If the result still contains %25 or %2F, the text was encoded twice — common when URLs are passed as parameters to redirects or tracking links. Decode again to see the original.
