FAQ
What is a query string?
A query string is the part of a URL after the question mark (?) containing key=value pairs separated by ampersands.
Does it handle duplicate parameters?
Yes. If the same parameter appears multiple times, all values are shown, including duplicates like hobby=coding&hobby=reading.
Are decoded values shown?
Yes, percent-encoded values are automatically decoded for readability. For example %20 becomes a space.
Is my URL data sent to a server?
No. All parsing happens locally in your browser using the URLSearchParams API.
Is this tool free?
Yes, completely free with no usage limits or sign-up required.
