Why ToolPorch

Most free tool sites make you dodge popups, create an account, or upload your data to someone's server before you can do one simple thing. We built ToolPorch the other way around: each tool loads instantly, works offline once loaded, keeps your data on your device, and looks good projected on a classroom screen. Fullscreen mode is always clean — no clutter, ever.

ToolPorch is free to use and supported by unobtrusive ads on regular pages (never in fullscreen mode). New tools are added regularly — if something you need is missing, tell us.
