Free Tools for Everyone,
Built with Care
ToolsFree.ai was created with a simple belief: essential online tools should be accessible to everyone, without paywalls, signups, or hidden fees.
Our Mission
Every day, millions of people search for simple online tools — a mortgage calculator, a unit converter, a password generator. Too often, they land on websites cluttered with intrusive ads, requiring account creation, or hiding the best features behind a paywall.
We built ToolsFree.ai to be different. Every tool on our platform is 100% free, requires no signup, and works instantly in your browser. Your data stays on your device — we don't collect, store, or sell any personal information.
Whether you're a student calculating compound interest, a developer formatting JSON, or someone converting units for a recipe, we want to be the tool you reach for first.
Always Free
No premium tiers, no feature gates, no "free trial" tricks. Every tool is fully functional from the moment you arrive.
Privacy First
All calculations run in your browser. We don't track your inputs, store your data, or require any personal information.
Instant Results
No loading screens, no server roundtrips. Tools respond in real-time as you type, powered entirely by client-side technology.
Works Everywhere
Fully responsive design that works on desktop, tablet, and mobile. Use our tools wherever you are, on any device.
