How it works

One job. Three steps.

01

Add a file

Select or drop a supported file directly into Muto.

02

Choose output

Muto detects the file type locally and shows relevant conversion options.

03

Convert locally

The conversion runs on your device and the result is saved back to you.

Ownership

Software as a tool, not a rental.

Muto is designed around local ownership. The extension does not require an account or cloud workspace to perform its core job. Keep your own copy, keep your own files, and keep control of your data.
