About IT Util Box

IT Util Box is a free, open-source collection of handy online tools for developers and people working in IT. It brings together the small utilities you reach for during everyday work — encoding and decoding, hashing, formatting, converting, inspecting, and generating — in one fast, focused place.

Local-first and private

Every tool runs entirely in your browser. The values you paste in are processed on your own device and are never uploaded to a server. There are no accounts and nothing to install. Your favorites, theme, and language are stored only in your browser's local storage.

Open source

IT Util Box is built on top of the open-source it-tools project, which is released under the MIT license. We are grateful to its authors and contributors.

What's inside

Tools are grouped into categories including Crypto, Converters, Web, Text, Data, Network, Math, Measurement, Images & Videos, and Development — each a single-purpose utility that does one job well.
