What is Mii Maker?

Mii Maker is a browser-based editor for Nintendo 3DS Mii data. You can create Mii characters with Chinese characters and special symbols, upload and edit Mii files extracted using tools like Mii Manager, then save and reimport them back to your 3DS.

It also supports creating special Miis (golden Mii) and generating QR codes that work on unmodified consoles — no custom firmware required.

How to Use Mii Maker?

  1. Use the "Open" button to upload a Mii file exported by Mii Manager or other tools
  2. Edit Mii properties including name, creator name, height, weight, and more — Chinese characters and special symbols are fully supported
  3. Click "Save" to download the modified .3dsmii file
  4. Use Mii Manager or similar tools to reimport the file back to your 3DS
  5. Alternatively, click "Generate QR Code" for a QR code that works on any 3DS without modification

Why Use Mii Maker?

Frequently Asked Questions

Can I use Chinese characters in Mii names?

Yes. Mii Maker fully supports Chinese characters and Nintendo special symbols in Mii names and creator names. Simply type them directly into the name fields.

How do I get Mii files from my 3DS?

Use Mii Manager (available on the Nintendo 3DS homebrew scene) to export Mii data from your console. The exported .3dsmii files can then be opened in Mii Maker.

Will QR codes work on unmodified consoles?

Yes. QR codes generated by Mii Maker are standard Nintendo Mii QR codes and can be scanned on any Nintendo 3DS using the built-in QR scanner in Mii Studio — no custom firmware or modification required.

How do I import edited Miis back to my 3DS?

After saving your edited Mii, use Mii Manager or a similar tool to import the .3dsmii file back to your 3DS SD card.

Is my data sent to any server?

The preview image is generated by Nintendo's official Mii Studio API, but all Mii editing happens locally in your browser. No Mii data is uploaded or stored on external servers.
