URL Decode
Paste an ugly, percent-encoded URL and get a readable version — the query string is decoded and split into one parameter per line.
The readable version appears here…
Parameter names and values are highlighted; the query string is split into one parameter per line. Everything happens in your browser.
Why URLs look like this
URLs may only contain a limited set of ASCII characters, so browsers percent-encode everything else — a space becomes %20, a colon %3A. Combined with long query strings from search pages, campaign links or SSO redirects, the result is unreadable. This tool decodes the URL and lays the query string out line by line so you can actually see what's in it.
FAQ
- Is the URL I paste sent to a server?
- No. The page is fully static and decoding happens with JavaScript in your browser — the URL never leaves your device.
- What gets highlighted?
- Query parameter names are shown in teal and their values in yellow, with one parameter per line — handy for comparing campaign URLs or debugging redirects.
