About Tooligan
Tooliganis a small, independent project that builds fast, single-purpose web tools — calculators, converters, generators, and document makers — and gives them away for free. The idea is simple: the everyday tasks people reach for a tool to do (working out a loan payment, converting units, splitting a bill, generating an invoice) shouldn’t require an account, a download, or a paywall. You open the page, you get your answer, you move on.
What you’ll find
Every tool lives in a clear category, so it’s easy to find and easy for search engines to index on its own:
- Converters — length, weight, temperature, pressure, and more, with the definitions and exact factors behind each unit.
- Finance calculators — loan and mortgage payments with full amortization, compound interest, salary-to-hourly, and tip splitting.
- Generators — styled QR codes you can colour, shape, and download as PNG or SVG, plus other one-off artifacts.
- Documents & billing — printable PDF invoices, receipts, and quotes with line items, tax, and your own logo.
We add tools steadily rather than all at once. We’d rather ship a handful that work really well — documented with how-to steps, worked examples, the underlying formula, and answers to common questions — than a hundred thin ones that don’t.
How the tools work with your data
Tooligantools run entirely in your browser. The numbers, text, and files you type into a calculator or document maker are processed on your own device — they are not uploaded to or stored on our servers. That means you can plug in real figures (an actual salary, a real loan balance, a client’s details on an invoice) without them ever leaving your computer. Some tools save your preferences and in-progress drafts in your browser’s local storage so they’re still there when you come back; clearing your browser storage removes them. The full detail is in our Privacy Policy.
Who’s behind it
Tooligan is run by a small, independent team. We build our own tools and write our own copy — nothing here is scraped or auto-spun from somewhere else. Our guides and blog posts are written by Wyatt Hutchins, who explains the math behind the tools in plain language and without the filler. You can read more about him and find every article he’s written on his author page.
Accuracy & how we keep it
We only publish a calculator once we’ve checked its output against worked examples, and we keep an eye on the figures as rates and conventions change. Even so, the tools are provided for convenience and information only. A formula can’t account for every real-world variable — local taxes, fees, and rules vary — so you should verify any output before relying on it for a legal, financial, medical, or other consequential decision. If you ever spot a result that looks wrong, tell us and we’ll investigate. The full disclaimer lives in our Terms of Use.
How Tooligan stays free
The tools are free, and we intend to keep them that way. Tooligan is funded by advertising, which covers hosting and lets us keep building without charging users or hiding features behind a subscription. We show ads only after you consent to advertising cookies, and you can change that choice at any time from the cookieslink in the footer. We don’t sell your personal information.
