About Us

What is Toolzio?

Toolzio is a free platform of premium calculators, converters and generators built to make everyday tasks faster, easier and more accurate.

Finance, health, maths, text, developer, SEO, image and many other utilities — each with a clear formula, worked example and FAQ.

Toolzio is supported by clearly-labelled, unobtrusive advertising, so the tools stay free for everyone with no registration required.

Wherever possible, calculations run entirely in your browser. We do not upload or store your inputs, text, images or files.

Tools support metric and imperial units, multiple currencies and work on any device. We aim for WCAG 2.2 AA accessibility.

Every published tool has an automated test suite covering normal, edge and error cases before release.
