All the tools

What is IT Util Box?

IT Util Box is a free collection of small, focused utilities for developers and people working in IT. Encode and decode, hash, format, convert, inspect, and generate — each tool does one job well, with no setup and no sign-up. It is an open-source project, built on top of the it-tools project, and it runs entirely in your browser.

Runs in your browser, stays private

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

What you can do

Crypto — generate tokens and passwords, hash and encrypt text, work with BIP39 and bcrypt.
Converters — move data between JSON, YAML, XML, Base64, and other everyday formats.
Web — encode URLs, decode JWTs, escape HTML, and inspect browser and request values.
Text — transform case, diff, count, and clean up text for content and code.
Data — parse, validate, and format structured data before you use it.
Network — inspect IPs, generate MACs, and work with common network values.
Math & Measurement — calculate, estimate, and measure without leaving your workflow.
Images & Videos — create and inspect browser-friendly media for docs and prototypes.
