Turn Your MIDI Files Into Real Sheet Music — Without Leaving the Browser

I have a folder full of MIDI files from old composition projects. They're great for playback, but useless when I want to hand a score to a pianist or import something into Finale. Most MIDI-to-sheet converters are either desktop software with painful licensing or online tools that want you to upload your files to who-knows-where. So I built one that runs entirely in the browser. Drop a .mid or .midi file in, and seconds later you're staring at properly rendered sheet music. Export it as MusicXML
