Disclaimer
What our results mean, and where you should get professional advice instead.
Last updated February 2026
General information only
Everything produced by the tools on this site is for general information. We make no promise that a figure, conversion or converted file is accurate enough for a specific decision, and results should be checked when the outcome matters.
Health tools are not medical advice
Health-related calculators, including the BMI calculator, use simple published formulas. They do not consider muscle mass, body composition, age, pregnancy, ethnicity or medical history, and they are not a diagnosis. Speak to a qualified healthcare professional about your health.
Financial and tax figures
Discount, tip and percentage tools perform arithmetic only. They do not account for local tax rules, rounding conventions, service charges or contractual terms. Do not use them as a substitute for advice from an accountant or financial adviser.
Documents and images
Converting, compressing, splitting or rotating a file changes it. Compression is often lossy, which means visible quality can drop, and some PDFs contain features that cannot be preserved in every operation. Always keep your original file, and check the output before you send or delete anything.
Time, units and colour
Time zone results depend on your device's clock and its time zone data, and daylight saving rules change. Unit and colour conversions use standard reference values and may round for display.
