Extract text from Mario Paint songs (MIO)
To convert MIO songs to another format, you need Entis GLS or Mario Paint or other Audio software.
To convert other file formats to the "Proprietary Audio Format" file type, you need software like Entis GLS or Mario Paint or a similar tool.
The .MIO file extension is primarily used for Music Interleaved Orthogonal audio files created by Entis Corporation. This is a highly specialized, proprietary audio format typically found in Japanese software and visual novel games. It utilizes custom compression that standard media players cannot natively decode.
Another major use of the .MIO format is in the homebrew and emulation community for the Nintendo DS. These files act as sequence data for Mario Paint Composer or offline posts for the DSi Miiverse Offline project. A smaller percentage of .MIO files are WarioWare D.I.Y. Microgame files or MioEngine Application files.
The primary disadvantage of the .MIO format is extreme fragmentation. Because four completely different software ecosystems use the exact same file extension, your operating system will rarely know how to open it. Standard audio players like VLC or Windows Media Player will fail to play it. Furthermore, the Nintendo DS variants are not actually audio waveforms; they contain raw sequence data, emulator parameters, or user-generated game logic.
Users typically want to convert .MIO audio files to standard formats like MP3, WAV, or OGG to play the music on modern devices. However, because .MIO is a closed, proprietary format, standard online converters almost always fail to process it. Usually, only the original software or specialized decoders can properly read or export the data.
Just drag and drop your .MIO file to identify the format, view it, and convert it when possible. convert.guru will inspect the file header, show text or internal content, and if our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your MIO file, detects the exact format, and lets you read the text inside.
Users also converted BIO files.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our MIO converter.
