About MU Tools

What is MU Tools

MU Tools is a free, registration-free collection of web tools that run entirely in your browser. We bundle the small, recurring tasks you bump into every day into single-purpose tools that you can open and finish in seconds.

The lineup covers PDF and image editing, text formatting and analysis, web data inspection, and developer utilities — the kind of things that quietly speed up web production and everyday office work. Every tool is available in both Japanese and English.

Features

Runs entirely in your browser

In principle, every tool is designed so that all processing happens inside your browser (on your device). Text you type and files you upload are never sent to or stored on our servers.

Exception: a small number of tools that look up external public data sources (URLs, domain names, IP addresses, and the like) need to make server-side requests to do their job, by the nature of what they do.

No account, completely free

There are no accounts and no sign-ups. Everyone is free to use the tools — both for personal and commercial purposes.

A quiet, distraction-free experience

We keep the UI clean and skip the heavy advertising and complicated settings so you can focus on the tool itself.

Multilingual and mobile-friendly

Every tool is available in Japanese and English, and the interface is designed to work comfortably from a smartphone browser as well.
