THE BASICS
What's the Difference Between .mid and .midi?
There is no technical difference. Both .mid and .midi are file extensions for the Standard MIDI File (SMF) format. The.mid extension originated from the 8.3 filename convention of the MS-DOS era, where file names were limited to 8 characters plus a 3-character extension. .midi is the modern, more descriptive extension.
Converting a .mid file to .midi is simply a file rename — the underlying binary data is identical. Both extensions use the same specification and are interchangeable in any DAW, synthesizer, or MIDI player.
Some applications or platforms may require the .midi extension for compatibility, which is why this conversion tool is useful for ensuring your MIDI files work everywhere.
