About ViteTools
Free, fast, and private tools for everyday calculations — no sign-up, no tracking, no nonsense.
Our Mission
ViteTools was built around a simple idea: essential calculators and converters should be free, fast, and respectful of your privacy. Too many tools online bury you in ads before you can use them, require account creation for basic features, or quietly send your financial data to a server. We think that's wrong.
Every tool on ViteTools runs entirely in your browser. When you enter your salary, health data, tax figures, or anything else — that information stays on your device. It is never transmitted, stored, or processed by us. We have no database of your calculations, because we never see them.
What We Offer
ViteTools is a growing collection of 75+ free calculators and tools organized into nine categories:
Whether you need to quickly convert your annual salary to an hourly rate, estimate your mortgage repayments, check your BMI, calculate VAT, or count words in an essay — there's a tool for it here, and it works instantly without any loading delay.
Why We Built This
The story behind ViteTools is straightforward. The tools that exist to answer everyday financial and personal questions are scattered, slow, ad-heavy, or demand your email before you can use them. We wanted one place where anyone can get a reliable answer in seconds — no friction, no registration wall, no data harvesting.
We also believe good tools should be genuinely educational, not just black boxes that spit out a number. That's why each calculator on ViteTools includes an explanation of the underlying formula, worked examples, and answers to the most common questions people have about that topic. We want you to understand your results, not just copy them.
Our Principles
Private by Design
All computation happens in your browser. No tool input ever touches a server. Your salary, health, and financial data is yours alone.
Fast by Default
Results appear instantly. No loading spinners, no server round-trips, no waiting. Every tool is built to respond in milliseconds.
Free Forever
Every tool on ViteTools is free. We keep the lights on through unobtrusive advertising — no paywalls, no premium tiers, no upsells.
Educational, Not Just Functional
Each tool explains the formula it uses, shows worked examples, and answers common questions. We want users to understand their results.
Accessible to Everyone
Tools are built with semantic HTML, keyboard navigation, screen reader support, and responsive design that works on any device.
Constantly Improving
We regularly add new tools, fix issues, and improve existing calculators based on user feedback. The site is actively maintained.
Important: Tools Are for Reference Only
While we work hard to keep every calculator accurate, all results are estimates for informational purposes only. Tax laws change, financial situations vary, and health metrics have nuance that a calculator cannot fully capture. Please do not make major financial, medical, or legal decisions based solely on any tool result. Always consult a qualified professional when the stakes are high.
