About Utilo

Utilo is a growing collection of 20+ free online tools for developers, designers and anyone who works with data. We built it because we were tired of utility sites that are slow, cluttered, or quietly upload your data to a server.

Our principles

• Private by design. Every tool runs entirely in your browser. Your JSON, images, passwords and tokens never leave your device.
• Fast. Static pages served from a global edge network, heavy work in Web Workers, no sign-up and no waiting.
• Beautiful and accessible. A clean interface in 10 languages with dark mode, keyboard shortcuts (⌘K / Ctrl K) and responsive layouts.

Free to use

Utilo is free. To keep it that way we may display non-intrusive advertising. Ads never have access to the data you process with our tools.
