About ToolDune
ToolDune is a collection of small, fast, honest web tools. No accounts, no paywalls, no selling your data — each tool does one job and gets out of your way. Bookmark us and the tide of small annoyances goes out.
Private by architecture
Every tool runs entirely in your browser. The numbers and text you type never reach a server — there is simply nothing to send.
Fast on any device
No frameworks, no bloat, no spinner. Pages are tiny and load instantly, even on a slow mobile connection or an older device.
Free, forever
No accounts, no paywalls, no locked features. Supported by unobtrusive ads — never by selling data or gating the tool you need.
