What is User-Agent Parser?

Parse browser, operating system, device, engine, and bot hints from User-Agent strings.

    How to use it

    1. Paste the User-Agent Parser content you want to process.
    2. Adjust quality, size, or output options when available.
    3. Run the tool to user-agent parser and preview the result on the page.
    4. Copy the output or download the generated file when it looks right.

    Best use cases

    • Clean developer data during debugging, API work, and documentation.
    • Clean content before saving configs, sharing snippets, or importing tables.
    • Use it when privacy matters and the input should stay inside the browser.

    Official standards and scope

    RFC 9110 defines the HTTP User-Agent field, the HTML Standard describes navigator.userAgent, and the Client Hints report documents a more structured alternative signal. This page uses fixed substring and regular-expression checks for a small set of browsers, operating systems, device classes, engines, and bot words. It is a heuristic summary, not a complete grammar parser: compatibility tokens and unfamiliar products can be misclassified, Windows 10 and 11 are not distinguished, versions are only extracted for selected tokens, and User-Agent Client Hints are not consumed.

    Notes

    • Browser support for User-Agent Parser can affect preview and export behavior.
    • Invalid input will show an error when possible, but the tool will not guess missing fields.
    • Preview the result before using it in production, publishing, or submission workflows.

    FAQ

    Is parsing exact?

    No. User-Agent parsing is heuristic, but it is useful for quick log and browser checks.

    Is User-Agent Parser free to use?

    Yes. You can use it directly in the browser without creating an account.

    Does User-Agent Parser support batch processing?

    Text tools usually process one pasted input at a time, so split large jobs into smaller inputs.

    Are files or content uploaded?

    User-Agent Parser runs in your browser, so your input or files are not uploaded to DataHub servers.

    Can I use User-Agent Parser on mobile?

    Yes, but desktop browsers are better for large files, batch conversion, or long text input.

    Why can conversion or validation fail?

    Common causes include invalid syntax, missing required fields, or invisible characters copied with the input.

    Can I use the result commercially?

    The tool only processes your own input. Commercial use depends on the rights of the original file or data.
