Convert MPY to another file type
To convert MPY MicroPython files to another format, you need MicroPython or other Developer software.
Convert a file to MPY
To convert other file formats to the "Compiled Bytecode Module" file type, you need software like MicroPython or a similar tool.
About MPY files
.MPY files are primarily compiled bytecode modules for MicroPython and CircuitPython. Developers use these files to execute pre-compiled Python code directly on hardware. This approach saves RAM and limited flash storage space on small microcontrollers. A smaller percentage of .MPY files are proprietary encrypted music files used by streaming services like KuGou and KuWo Music.
The main disadvantage of the .MPY bytecode format is its lack of human readability. Unlike standard PY scripts, you cannot open these files in a text editor to modify the code. If you lose the original source code, editing the module becomes a massive problem. Decompiling MicroPython bytecode back to readable text is extremely difficult, and you will permanently lose comments and formatting. Furthermore, .MPY files are strictly tied to specific firmware versions. Bytecode compiled for one MicroPython version frequently crashes on another.
For the audio variant, KuGou uses heavy DRM (Digital Rights Management) encryption. This proprietary lock prevents playback on standard media players like VLC. Users often face frustrating limits, such as requiring an active subscription to a specific mobile app just to listen to files stored on their own hard drive. Standard online converters fail to process .MPY files because they lack the specific version-dependent decompilers for bytecode, and they do not possess the proprietary decryption keys for the audio variants. Our tool can inspect the file, reveal internal headers to confirm if it is bytecode or encrypted audio, and extract plain text strings when available. If you have the audio variant and can bypass the DRM, the best target formats are MP3 or WAV. For code, your only real solution is to locate the original PY source file.
Convert.Guru analyzes your MPY file, detects the exact format, and lets you read the text inside.
If you want to convert MPY file to JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO, RS or SWIFT, you can use MicroPython or similar software from the "Compiled Python Bytecode Storage" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to MPY, try MicroPython or another comparable tool in the "Compiled Python Bytecode Storage" category.
The MPY Converter Story
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 MPY converter.
