About ToolFu
Free, fast, privacy-first online tools for everyone.
Why ToolFu?
Most online tools are slow, cluttered with ads, and send your data to servers you don't control. ToolFu is different. Every tool runs entirely in your browser -- your files, your JSON, your PDFs never leave your device. No accounts. No tracking. No nonsense.
The name "ToolFu" comes from kung fu (功夫) -- meaning mastery through practice. We believe tools should feel effortless, like a martial artist who makes the complex look simple.
Privacy First
All processing happens on your device. Zero data collection.
Blazing Fast
No server round-trips. Results are instant, every time.
Works Offline
Once loaded, tools work without internet. Great for travel.
