URL Parser — Decompose and rebuild query
Paste a URL to see protocol, host, path, query table, and hash. Edit query rows and copy the rebuilt URL. Password in userinfo is masked by default. Percent-encoding a component stays on URL Encode / URL Decode.
Developer notes
• Parser is WHATWG URL — distinct from the percent-encoding module used by URL Encode / URL Decode. • Query names and values are decoded URLSearchParams rows; rebuild re-encodes. • Userinfo password is masked until you reveal it. The rebuilt URL still contains the password if it was in the paste. • FastMinify never fetches the URL.
When this is the right tool
• See every query pair without squinting at a long search string. • Add or remove a parameter and copy the rebuilt URL. • Inspect a URL that contains a password without showing it on screen by default.

URL Parser FAQ
Decompose and rebuild — not percent-encoding
Should I use URL Encode instead?
Use URL Encode or URL Decode to percent-encode a single component. This parser decomposes a full URL and rebuilds the query table.
Is the password copied?
The on-screen field is masked by default. Copy rebuilt URL includes userinfo if it was in the paste — treat that clipboard like a secret.
Does this fetch the URL?
No. Parsing is local. FastMinify never requests the host.
Are query values decoded?
Yes. The table shows decoded URLSearchParams names and values. Rebuild re-encodes them.
