About Qivtools

Qivtools is a growing set of small tools that help you calculate, convert, generate and compare without creating an account or waiting on a spinner.

Every tool on this site runs in your browser. The numbers you type — salaries, ages, bills — are not sent to our servers. Search queries stay on the page unless you choose to share a link.

There are currently 171 tools, with a structure that can grow to hundreds.

Qivtools is not medical, legal or tax advice. BMI categories follow WHO adult ranges; salary conversions are gross pay only.
