Health disclaimer

The BMI calculator gives a rough screening number from your height and weight. It does not measure body fat, muscle, or health on its own. A very muscular person can have a high BMI and be fit, and a normal BMI does not rule out health problems. Do not use a BMI result to diagnose yourself, to start or stop any diet, exercise plan or treatment, or to make any health decision. Talk to a doctor or other health professional about what the number means for you.

Estimates, not exact answers

Every number on this site is a calculation from the figures you type in. The unit converter rounds its answers for reading — the maths behind them uses exact definitions. The age calculator counts real calendar days, including leap days. The percentage calculator uses plain percentage maths. The worked examples on the site were checked against the tools, but they are examples, not a promise. Use the results as a rough check, not as the final word.

Files are processed on your device

The PDF and image tools run fully in your browser. Your files are never uploaded to any server, never stored by us, and never seen by anyone else. That also means the result exists only on your device: if you close the tab before downloading the merged PDF, the split pages, the compressed file or the converted image, the result is gone and cannot be recovered from us. Download your result before you leave the page. We are not liable for files lost this way.

Passwords

The password generator makes a random password on your device and never sends it anywhere. Once you close the tab, the password is gone unless you saved it. A strong password only helps if nobody else knows it: do not share it, do not email it to yourself, and do not reuse it on more than one site. We are not liable for an account lost because a generated password was not saved, shared, or reused.

No professional relationship

Using this site does not create a professional relationship between you and us. We are not your doctor, your financial adviser, your accountant, or your lawyer, and reading this site or using a tool does not make us one. We do not review your health, your money, or your files, and we do not take responsibility for any decision you make based on a number or a file you saw here.

No guarantee

We work to keep the tools right, but we do not guarantee that any number or file on this site is correct, complete, or up to date at the time you read it. The site is provided as-is, and you use it at your own risk. If you find a mistake, please tell us — that is how the site gets better.
