About ClickWebTools

ClickWebTools is a collection of free online tools for everyday calculations, conversions and text tasks. Each tool does one job, opens instantly and explains how it reaches its answer.

How the tools work

Calculators, converters, text tools and developer tools run in your web browser using JavaScript. The numbers and text you enter are processed on your device and are not sent to our server.

How we check accuracy

Formulas come from published standards where they exist: exact unit definitions from the 1959 international yard and pound agreement, BMI categories from the CDC and WHO, and JSON parsing from RFC 8259. Each tool page shows its formula and worked examples so you can verify a result yourself. Calculations keep full precision and round only for display.

What the tools are not

Health, salary and finance tools give general estimates. They are not medical, tax, legal or financial advice. For decisions that matter, check with a qualified professional.

How the site is funded

ClickWebTools is free and needs no account. It is supported by advertising, which is kept separate from the tools themselves.
