About & Contact

1pagetool.com is a collection of tiny, single-purpose tools. Each page does one thing, works entirely in your browser, and shows its answer immediately.

How it works

No accounts. No logins. No data leaves your device - every calculator and converter runs client-side in your browser. Open a tool, type or paste, get the answer, leave.
