About ToolDune

ToolDune is a collection of small, fast, honest web tools. Each tool does exactly one job — count down to a date, split a dinner bill, convert kilometers to miles — and does it without asking you for an account, a download, or your personal data.

Our principles

• Private by architecture. Tools run in your browser. We couldn't see your inputs even if we wanted to.
• Fast on any device. No frameworks, no bloat — pages load instantly, even on slow connections.
• Free forever. The site is supported by unobtrusive advertising, never by selling your data or paywalling a tool you need.

The site is actively maintained — new tools are added regularly based on what people actually search for.
