About us
Who we are
FireToolLand is a free website of online tools, run by FireToolLand. You will find calculators for finance, tax, salaries, health, maths and dates, converters, developer and text tools, PDF and image tools, astrology and other tools. There is no account, no sign-up and no download. The calculations and file processing run in your browser.
How a tool is made
Each calculation is written in code and tested against known results. For rules that differ by country, we also test against official examples. Every tool page shows the formula, a worked example, the sources and the date of its last check.
