URL Query Parser
Extract and inspect URL query parameters.

How to Operate URL Query Parser
Deconstruct complex URLs into discrete protocol, domain, path, hash, and query parameter components for inspection, debugging, and testing.
- 1 Select "Complete URL" or "Query String Only" mode and paste your text into the input field.
- 2 Click "Parse URL" to extract all parameters and URL structure.
- 3 Inspect URL details (protocol, hostname, path, fragment) and summary statistics.
- 4 Filter or search parameters by key, value, duplicate status, or missing equals signs.
- 5 Copy parameters or download structured data as JSON or CSV.
Example Input & Output
https://example.com/products?category=books&page=2&sort=price
{
"category": "books",
"page": "2",
"sort": "price"
}
Supported Inputs
- Standard HTTP/HTTPS URLs with query strings and fragments
- Raw query strings with or without leading question mark (?)
- Percent-encoded UTF-8, Unicode characters, and plus-encoded spaces
Browser Technical Limits
- Entered URLs are treated strictly as text and are never fetched, visited, or executed.
- Invalid percent-encoded sequences are safely isolated with visual warnings.
Frequently Asked Questions
Everything you need to know about URL Query Parser, formats, and privacy guarantees.
What is the difference between a missing value and an empty value?
A parameter like ?flag has no equals sign, meaning its value is omitted (hasEquals: false). A parameter like ?flag= explicitly contains an equals sign, meaning its value is defined as an empty string (hasEquals: true). UtilityHub distinguishes between these two states.
Why are plus signs (+) decoded as spaces?
According to the application/x-www-form-urlencoded query string standard, spaces in query parameters are conventionally encoded as plus signs (+) or percent-encoded as %20. UtilityHub automatically decodes plus signs into spaces.
How does UtilityHub handle repeated query parameters?
Unlike standard JavaScript objects or basic parsers that overwrite duplicate keys, UtilityHub preserves every single parameter occurrence in its original sequence, highlights duplicate keys, and groups them in the duplicate analysis dashboard.
Does UtilityHub send my URLs to an external server?
No. The entered URL is processed 100% locally in your browser using the native browser URL API. No network requests are made to fetch, visit, or log your URL.
Can I parse raw query strings without a full domain?
Yes. You can paste a query string with or without a leading question mark (e.g., ?category=tech&page=2 or category=tech&page=2). Any trailing fragment identifier (#) is cleanly separated and excluded from parameter values.
