URL Parser and Query Builder

Paste an absolute URL to split it into its parts. Edit the query pairs and the URL is rebuilt with correct percent-encoding.

URL (must start with a scheme, such as https://) Form encoding (a + means a space in query names and values)

Enter a URL.

Parts

Part	Value

Query pairs

Pairs are kept in order, and a repeated name stays repeated. Edit a name or value, add a pair, or remove one.

Name (decoded)	Value (decoded)	No = sign	Remove

Rebuilt URL

Nothing you type is sent, stored or saved, and the URL is not requested. The page does not visit the address it parses.

How it works

The URL is split by its own rules: the scheme comes first, then // introduces the user, password, host and port, then the path, then the query after ?, then the fragment after #. Only absolute URLs with a scheme are accepted. A relative URL, or one with no scheme, is refused with a message.

Each query pair is split at its first =, so x=1 and x=1&x=2 keep their order and their repeated name. A name with no = has no value at all, and that is kept as written.

Names and values are shown decoded. Rebuilding encodes each one again: a space becomes %20, or + when form encoding is ticked, and every other character outside the unreserved set is written as its UTF-8 percent escape. The same values come back, but the escapes may be written differently from the original text. A malformed escape such as %G1, or bytes that are not valid UTF-8, is refused and the position is shown.
