About Utilixo Tools
Why we built this
Most "free online tool" sites ask for your email, show four ads before the input box, and quietly upload whatever you paste into them. That is a bad trade for something as small as formatting a JSON file or working out a tip.
Utilixo Tools takes the opposite approach. Every tool is a static page that runs in your browser. Your text, your numbers and your files never leave your device, because there is nowhere for them to go.
What we stand for
- Free, with no paywall. Every tool is available without an account.
- Private by architecture. Processing happens client-side. Open the network panel while you use a tool and you will see no upload of your input.
- Fast and simple. No cookie banners, no newsletter pop-ups, no tracking scripts beyond what is needed to serve the page.
- Honest about limits. Calculators state their assumptions. Estimates are estimates, not advice.
How the numbers are calculated
Each tool documents the formula it uses. Financial tools use standard time-value-of-money formulas; health tools use published equations such as Mifflin-St Jeor for basal metabolic rate; unit converters use official conversion factors. Where a method has known limits, the page says so.
