MIDI (Musical Instrument Digital Interface) is a binary file format ( .mid or .midi ) that stores musical performance data: notes, timing, tempo, instruments, etc. print(b64_string[:100]) # preview decoded_bytes = base64

certutil -encode my_song.mid output.txt (Then remove the -----BEGIN CERTIFICATE----- lines manually.) Python (most common) import base64 Read MIDI file as binary with open('song.mid', 'rb') as f: midi_bytes = f.read() Encode to Base64 string b64_string = base64.b64encode(midi_bytes).decode('utf-8') const midiBuffer = fs.readFileSync('song.mid')

with open('song_package.json') as f: data = json.load(f) midi_bytes = base64.b64decode(data['midi_base64']) with open('restored.mid', 'wb') as out: out.write(midi_bytes) If your MIDI is generated in memory (e.g., using midiutil or pretty_midi in Python), encode directly:

base64 -i my_song.mid -o my_song_base64.txt Or to output directly:

is a text encoding scheme that converts binary data into ASCII characters (A–Z, a–z, 0–9, +, /, =).
