What's the difference between M4A and MID?

M4A Audio is mpeg-4 audio container commonly used by apple for aac and alac content. MIDI File is musical instrument digital interface — note instructions, not audio. Key difference: M4A Audio excels at Apple ecosystem standard with iTunes/Apple Music integration, while MIDI File offers tiny file sizes, infinitely editable musical score data.

How does the M4A to MID conversion work technically?

Xonvert uses WebAssembly-compiled libraries to decode your M4A file in-browser, process the audio data, and re-encode it as MID. All processing happens on your device's CPU.

What happens to my files after conversion?

Nothing — your files exist only in your browser's memory during conversion. Once you close the page, all data is cleared. No files are stored anywhere.

Will the conversion strip my EXIF or metadata?

Xonvert preserves metadata (EXIF, XMP, ID3, etc.) when the target MID format supports it. You can optionally strip metadata in the settings for smaller, cleaner output files.

Does the conversion preserve metadata?

Xonvert preserves compatible metadata fields when converting between formats. Some format-specific metadata may not carry over if the target format doesn't support it.
