Frequently asked questions
Questions about URL & Query String Parser
What is a query string?
A query string is the portion of a URL after the question mark. It contains key-value parameters commonly separated by ampersands.
Can a query parameter appear more than once?
Yes. URLs may contain repeated keys such as tag=javascript&tag=typescript. This tool preserves every occurrence separately.
What is the difference between host and hostname?
The hostname contains the domain or IP address. The host includes both the hostname and an explicit port when one is present.
Are parameter values automatically decoded?
Yes. The browser URL and URLSearchParams APIs decode percent-encoded names and values when parsing them.
Is the URL uploaded?
No. Parsing, editing and rebuilding take place entirely inside your browser.
