About Biz Tools

Biz Tools is a free, open-access collection of 5 utilities built for speed and privacy. Every tool runs entirely in your browser — no data is ever sent to our servers, logged, or stored.

Our Philosophy

• Local-first: All computation happens on your device using browser APIs.
• No login required: Open a tool, use it, done.
• No tracking of inputs: Your data stays on your machine.
• Fast: Static pages with no server round-trips.
