How to Convert MIDI Files Online — Free & Instant
Convert MIDI files to MP3 or WAV — turn note data into real, playable audio.
Drag and drop your MID, MIDI, or RMI file. Unlike audio recordings, a MIDI file stores note and instrument data, which our converter renders into real sound.
Pick MP3 for a small, shareable file that plays anywhere, or WAV for uncompressed audio you can edit further. A high-quality General MIDI soundfont provides the instruments.
Download the rendered track and play it on any device — no synthesizer or music software needed. Uploads are deleted within 24 hours.

Why Convert MIDI Files?
A MIDI file contains instructions, not sound. Converting to MP3 or WAV renders those notes into actual audio you can play on any device or share with anyone.
Phones, browsers, and most media players can’t play raw MIDI. Convert to MP3 so your sequences play everywhere, just like any other song.
Send your music to people who don’t have MIDI software. An MP3 lets anyone hear your arrangement exactly as rendered, on any platform.
Convert MIDI to WAV or MP3 to drop backing tracks and themes into video editors, podcasts, and game engines that don’t accept MIDI.
MIDI playback varies by device and soundfont. Rendering to MP3 locks in one consistent, high-quality version of how your music should sound.
Convert MIDI audio directly in your browser — no desktop apps, no plugins. Files up to 10 MB are always free, and files are deleted from our servers within 24 hours.
