Disclaimer

General information only

The tools on Toolzaio are provided for general, everyday use. Their results are a convenience, not a professional service. Nothing on this site is legal, financial, medical or other professional advice.

Calculators give estimates

The Age Calculator, Percentage Calculator and BMI Calculator do simple, standard sums. Small differences in method can change a result slightly, so verify any figure before using it in a document, an application or a decision that matters.

BMI is not medical advice

A BMI number is a rough population-level guide. It does not measure your health, and it is not a diagnosis. For questions about your weight or health, talk to a doctor, not a web page.

Check files and codes before you rely on them

A compressed photo, a merged PDF or a generated QR code should be opened and checked before it is sent, filed or printed — especially in bulk. QR codes in particular should be test-scanned before they go on anything you cannot reprint.

Other websites

Where this site links to another website — for example TextToSpeechH — that site is run under its own terms and policies, and we are not responsible for its content.

Availability

We try to keep every tool working, but the site may be unavailable at times, and results may differ between devices and browsers. If something looks wrong, tell us and we will look into it.
