Query String to JSON Converter
Paste a query string or URL to decode parameters, repeated keys and percent-encoded values.
How to use this tool
- Prepare your URL or query string.
- Paste the content or choose a local file.

- Review the result, then copy or download it.
Suitable use cases
Use this tool for quick developer tasks, documentation, debugging, migrations, content preparation, or local file checks where the input and output format are clear. It is not a replacement for a full production parser, editor, or deployment validation pipeline.
Output format
The result is JSON object text or a browser-generated download, depending on the tool. Keep the original input and verify the output in the application that will consume it.
Privacy
Content is processed in the browser by the page. The tool does not require an upload to a conversion server. Do not paste secrets, personal data, or files you are not authorized to handle on a shared device.
Important: browser parsers cover common practical cases. Always review generated files before using them in production, especially for configuration, subtitles, images and security-sensitive data.
