About ToolBox
Free, fast, and private utility tools for everyone.
Our Mission
ToolBox was built with a simple mission: provide high-quality, free online tools that respect your privacy. In a world where most utility websites are cluttered with ads, require sign-ups, or upload your data to servers — we chose a different path. Most of our tools run 100% in your browser. Your data stays yours.

Our Technology
ToolBox is built with modern web technologies: Next.js 16 for server-side rendering and static generation, React 19 for the interactive UI, TypeScript for type safety, and Tailwind CSS 4 for styling. We use the Web Crypto API for hash generation, the browser-native Intl API for time zones, and the browser-image-compression library for image optimization — all running directly in your browser.
