About QuickToolBelt

QuickToolBelt is a small, focused collection of free online tools — calculators, converters, and generators for everyday tasks like splitting a bill, converting a recipe, or checking your age. Each tool lives on its own page and does one thing well.

How it works

Every tool runs entirely in your browser. There's no sign-up, no account, and no data sent to a server to use any tool — all calculations happen on your device. See ourPrivacy Policy for details on what that means for cookies and advertising.

Why it's free

QuickToolBelt is supported by advertising, which helps keep every tool free to use with no sign-up required. We aim to keep ads clearly separated from the tools themselves so they don't get in the way of actually using the site.
