Nothing you enter here is sent anywhere. There is no file and no request to our server - the work is done in your browser and disappears when you close the page.
How It Works
- Enter — Fill in the values the tool asks for.
- Run — Press the button; an empty field is reported by name rather than read as zero.
- Read — The answer comes with the working behind it, so you can check the figure.
- Take it — Copy the result, or download it where the tool offers that.
Frequently Asked Questions
Is a user agent trustworthy?
No — it is a self-declared string anyone can edit. The parser is for reading logs and debugging, not for security decisions or blocking users.
