Free URL Query String Parser
The SearchToolHub URL Query String Parser is a free browser-based tool for inspecting and understanding URL query parameters. It can extract parameters from a complete URL or parse a query string directly.
Query strings are commonly used for search pages, filters, campaign tracking, pagination, API requests, redirects and other web functionality. When a URL becomes long or contains encoded values, manually reading each parameter can be difficult. This tool converts those parameters into an easy-to-read table.
What Is a URL Query String?
A query string is the portion of a URL that normally appears after the question mark. For example:
In this example, q and page are parameters. Their values are seo and 2.
Multiple parameters are usually separated with an ampersand. The parser reads these pairs individually so you can quickly understand what a URL contains.

URL Query String Parser Features
SearchToolHub’s parser accepts a full URL, a query string beginning with a question mark, or a plain query string. Parameter values are decoded so encoded characters become easier to understand.
Repeated parameters are not silently removed. Each occurrence remains visible in the results table, which is important when inspecting URLs where the same parameter appears more than once.
Understanding UTM Parameters
Query strings are frequently used for campaign tracking. Common UTM parameters include utm_source, utm_medium, utm_campaign, utm_term and utm_content.
Parsing a tracking URL makes it easier to identify the campaign information attached to a link before it is shared or published.
URL Encoding and Decoding
URLs often contain encoded characters. For example, a space may appear as %20, while other characters can be represented by percent-encoded values.
This parser decodes the parameters so you can inspect their readable values while also showing the encoded representation.
Privacy-Friendly URL Parsing
This tool performs its parsing directly in your browser using JavaScript. The URL is not uploaded to SearchToolHub for parsing. This makes the tool convenient for inspecting URLs without requiring a server-side processing service.
Even so, avoid sharing URLs containing passwords, private credentials, access tokens or other confidential information with any online service.
