About the BMI Calculator tool
BMI Calculator estimates your Body Mass Index, a quick screening number based on your height and weight. It supports both metric and imperial units and tells you whether you fall in the underweight, normal, overweight, or obese range. BMI is a general guide rather than a diagnosis, but the BMI Calculator gives you an instant, private starting point for tracking your health.

Your privacy
The BMI Calculator runs entirely inside your web browser. Your files and text are never uploaded to any server, so your data stays private on your own device — just like the workflow trusted on sites such as iLovePDF and Sejda, but with nothing leaving your computer.
