About OmniTools

OmniTools is a free collection of online calculators and everyday tools built to do one thing well: give you a fast, accurate answer without friction. There is no sign-up, no download and no clutter.

Private by design

Every calculation runs entirely in your browser. The numbers you type are never sent to a server and are never stored. When you close the tab, they are gone.

Built to be useful

We focus on the tools people actually reach for — working out an age, a loan payment, a tip, a percentage or a due date. Each tool includes a short explanation and answers to common questions so you understand the result, not just the number.

We are adding new calculators regularly and translating them into more languages so the same clear, reliable tools are available wherever you are.
