FreeToolbox Ten focused tool sites, one team

Small tools that do one thing and get out of the way

We rebuild the everyday utilities the web already had — calculators, converters, text and file tools — and leave out the parts that made them unpleasant. No signup, no upload, no fifteen-field form before an answer.

Most of these tools already existed somewhere. They were written years ago, still get millions of visits a year, and have been quietly decaying ever since: buried under full-screen ads, unusable on a phone, hiding the one number you came for beneath a wall of unrelated text.

So we rebuilt the useful ones from their published methods, one topic at a time. Ten sites rather than one, because a lyrics generator does not help a mortgage calculator earn trust — each site covers a single subject properly instead of covering everything badly.

The ten sites

Each one is independent, and each links openly to the others.

What every site here has in common

The work happens in your browser. Your salary, your medical numbers, the PDF of a signed contract — none of it is uploaded, logged, or stored, because there is no server-side step to send it to. That is also why results appear as you type instead of after a round trip.

Every result is explained. Each tool shows the formula or specification it implements and a worked example you can check by hand, and says plainly where an estimate stops being reliable. A number you cannot interrogate is worth very little.

The sites are free and paid for by a small number of clearly labelled ads. No accounts, no email capture before results, no paid tier holding back the useful features, and no payment accepted to rank one product above another.

Common questions

Are these really run by one team?

Yes. Ten sites, one small team, and the footer on every page says so — that is the point of this page existing. The cross-links between them are ordinary same-owner links, the kind any site family has, and they are never disguised as independent recommendations.

Why ten separate sites instead of one big one?

Because being trusted on mortgages does not make you trusted on image compression, and a site that covers everything tends to cover it thinly. Splitting by topic lets each site go deep — thirty finance calculators, twenty file converters — rather than offering three of each.

How are the tools funded?

Advertising, labelled and kept away from the controls so nothing is clicked by accident. We do not sell data, require accounts, or paywall results. Where a page links to a commercial offer it is marked as sponsored, every time.

Is anything I enter sent to you?

No. Every tool runs in your browser, which means we could not see your inputs if we wanted to. It is also the reason there are no file size limits or daily caps — the only ceiling is your own device's memory.

Something is wrong. How do I report it?

Accuracy reports come first. Tell us what you entered and what you expected, and we will check it against the underlying method and fix it. The contact address is in the footer of every page.
