About Numelivo
Updated November 13, 2026
What Numelivo is
Numelivo is a free collection of calculators and small tools for everyday tasks: percentages, loans, dates, health screening figures, unit conversion, PDF and image editing, and developer utilities. It is available in Hebrew, English, Indonesian, Romanian, Vietnamese, Thai, and Hungarian.
Every page is written for its own language rather than copied from another one, so the wording, number format, and examples fit the people who read it.
How it works
The pages are static. When you use a calculator or a tool, the work is done by your own browser on your own device. The numbers you type and the files you choose are not sent to Numelivo, and there is no account to create.
Each calculator explains its method: the formula, a worked example, and the sources it relies on, so you can check a result instead of taking it on trust.
Who and why
Numelivo is an independent project. The aim is plain tools that load fast, work without sign-up, and say clearly what they do and do not do. Advertising may be added in the future to cover running costs; if so, the privacy policy will say so first.
The tools are for general information. Please read the terms of use and the disclaimer, and check any result that matters before you rely on it.
