About FreeTool
300+ free tools across 15 categories — no paywalls, no forced sign-ups, and nothing unnecessary leaving your device. Most tools work offline.
Our mission
We built FreeTool with one goal: high-quality utilities on the web that respect your privacy. Everyday tasks like formatting JSON, compressing images, or checking a domain should be free to use, quick to load, and trustworthy — without selling your data or hiding features behind accounts.
All tools run in your browser using modern Web APIs. Most work fully offline — no internet needed once loaded.
Privacy first
Most tools run in your browser; your files stay on your device.
Always free
No premium tiers — every tool is available to everyone, forever.
Works offline
Service worker caches tools — keep working even without internet.
Modern stack
Built with Next.js 15, Cloudflare Edge, and browser-native APIs.
