Free tools for everyday decisions.
UtilityLab is a free online platform offering over 220 calculators and tools for finance, health, development, images, construction, AI, and everyday life. We believe that useful tools should be simple, fast, and accessible to everyone — without sign-ups, subscriptions, or hidden fees.
Every website has a story. Ours started with a simple frustration: too many online tools are cluttered with ads, require you to create an account, or upload your data to a server without telling you. We wanted something different — a place where you could get a quick answer without giving up your privacy.
So we built UtilityLab. Every tool runs entirely in your browser. When you calculate a mortgage payment, compress an image, or format JSON, the processing happens on your device — not on our server. Your data never leaves your computer.
UtilityLab started with a handful of finance calculators. Today, we offer over 220 tools across several categories:
You can browse our complete Tools Directory to see every tool in one place.
Privacy is not an afterthought at UtilityLab — it is the foundation. Because all processing happens in your browser, your data never reaches our server. We do not store the numbers you enter, the images you process, or the text you handle. We also do not sell your data, because we do not have it.
We use Google Analytics to understand how visitors use the site (pages visited, time spent). This data is anonymous and helps us improve. You can read more in our Privacy Policy.
Running a website costs money — hosting, domain, and time. In the future, we may display ads to cover these costs. But the tools themselves will always be free. We will never charge for basic access or require a subscription.
Want to add a UtilityLab calculator to your own website or blog? You can embed any of our 220+ tools for free. Visit our Widgets page to get the embed code for any tool. All we ask is that you keep the small "Powered by UtilityLab" link visible, which helps us keep the tools free for everyone.
UtilityLab is built by a small team of developers and writers who believe the web should be useful, not frustrating. We are not a large company. We do not have investors or a marketing budget. We are just people who wanted better tools and decided to build them.
