Convert MIDI to CAF

Fast, free, and secure MIDI to CAF conversion. No registration required.

Xonvert turns midi into caf using WebAssembly — the same technology that powers AAA browser games. Both MIDI File and Core Audio Format are audio formats, but they differ in approach: MIDI File prioritizes universal music notation format for electronic instruments while Core Audio Format focuses on unlimited file size, supports every Apple audio codec. Professionals in music production, podcasting, and broadcasting rely on this specific conversion regularly. Xonvert uses the same powerful libraries that professional desktop applications rely on — FFmpeg, libvips, and more.
