Quick answers for URL Parameter Extractor
What does the URL Params Extractor do?
Paste any URL and it lists every query parameter (`?key=value&...`) and the URL fragment (`#anchor`). Each value can be copied individually, or you can grab the whole set as a JSON object - handy for documenting an API call or building a test fixture.
Decoded vs Raw - which should I use?
Decoded shows what the server actually sees after `decodeURIComponent` (so `hello%20world` becomes `hello world`). Raw shows the over-the-wire form. Use Decoded when reading values, Raw when you need to reproduce the URL exactly.
Does it handle URLs without a scheme?
Yes. If you paste `example.com/path?x=1`, the tool prepends `https://` to make it a valid URL. The displayed scheme will reflect the assumption.
How are repeated parameters handled?
The list shows every occurrence in order, so `?id=1&id=2` gives you two rows. The "Copy as JSON" output collapses duplicates into an array under that key.
Is the URL sent anywhere?
No. Parsing uses the browser's built-in `URL` and `URLSearchParams` APIs, all in your tab - useful when the URL contains tokens, session IDs, or anything else you wouldn't paste into a server-side tool.
