Tools Guides

About BoxTool

BoxTool exists to make the small, daily computing tasks easier: converting units, generating a QR code, formatting some JSON, splitting a PDF. We pick tools by what people actually search for, build them well, and ship them in six languages.

Our principles

  • Privacy by default. Almost every tool runs in your browser — we never see your data.
  • No signup. Open, click, done.
  • Speed. Pages load in under a second, even on slow connections.
  • Accuracy. Our calculators use published formulas, with sources cited where it matters.

How we pay the bills

Google AdSense pays for hosting and development. We never sell user data — we couldn't, because we don't have any.

{# Alpine.js — self-hosted. (The previous jsdelivr CDN tag had a stale SRI integrity hash, so the browser refused to run it and window.Alpine was never defined — silently breaking every FAQ accordion and Alpine tool.) #}
