About UtilHero
Free web utilities, zero clutter.
UtilHero is a growing collection of free, browser-based utilities — unit and colour converters, calculators, encoders, text and JSON tools, generators, and more. Each one is built to do a single job quickly and well, with no sign-up, no install, and no wading through ads to reach the thing you came for.
Private by design. Whatever you type, paste, or upload into a tool is processed in your browser— it isn't sent to, stored on, or logged by our servers. That means the tools are fast, work on any device, and keep your data yours.
Free, thanks to ads. UtilHero is funded by advertising rather than subscriptions, so everything stays free for everyone. We keep ads out of the way of the tools themselves, and you control ad personalisation through our cookie settings.
