About ToolIQ

ToolIQ is a free online tools website offering calculators, unit converters, and image conversion tools for finance, health, construction, math, and everyday tasks. Our goal is to provide fast, accurate, and easy-to-use tools without requiring sign-ups or clutter.

All calculations and image conversions run directly in your browser — no data is sent to our servers. We offer dedicated pages for popular conversions like cm to inches, kg to lbs, and Celsius to Fahrenheit, along with a full unit converter hub. We also offer image format converters for PNG, JPG, WebP, and more.

Our calculators cover mortgages, loans, compound interest, BMI, calories, macros, concrete, paint, percentages, salary, sales tax, tips, age, and date differences — with more on the way.

ToolIQ is supported by advertising to keep it free for everyone. We take your privacy seriously — see our privacy policy for details.
