MOD to CAF Converter
Processing entirely on your device — large files may take a moment.
Amiga Module and Core Audio Format exist for different jobs: MOD is the Amiga tracker format — samples plus a pattern table that the demo scene turned into an art form, replayed through its own synthesizer. Convert CAF files to WAV or MP3 for use outside the Apple ecosystem.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.
How MOD compares to CAF
| MOD | CAF | |
|---|---|---|

| Types / schema | Tracker module (samples + notes) | PCM/ALAC/AAC in CAF |
| Compatibility | libopenmpt, ProTracker, ffmpeg | afconvert, Logic Pro, ffmpeg |
| Best for | Demoscene and game music | Apple pro-audio workflows |

About the MOD format
MOD is where digital music composition started for a generation: the Amiga tracker format stores short PCM samples plus a pattern table of note events, and the player synthesizes the song live. It is not a waveform — it is sheet music and an instrument pack in one file, which is why 30KB can hold a full song.
Converting MOD to MP3 or WAV renders the song through the tracker engine exactly as it sounds — every player interprets the same patterns, so the render is faithful to the original scene release.
+ Strengths
- ✓Complete songs in tens of kilobytes
- ✓Rich demo-scene heritage
- ✓Self-contained samples + patterns
! Limitations
- −31 8-bit samples max in classic MOD
- −Player interpretation varies subtly
- −4-channel-era limitations
About the CAF format
CAF (Core Audio Format) is Apple's container for pro audio: 64-bit file offsets for recordings of any length, any codec as payload (PCM, ALAC, AAC), and time-stamped MIDI-style event chunks. Logic Pro exports it and macOS system sounds ship in it.
ffmpeg decodes the common PCM/ALAC payload variants, converting CAF to WAV or MP3 for use in any non-Apple DAW, player or web player.
+ Strengths
- ✓64-bit offsets — no size ceilings
- ✓Native to Logic Pro pipelines
- ✓Flexible codec payload
! Limitations
- −Apple-centric — rare outside macOS
- −Some CAF variants (UUID chunks) unsupported
- −Tag metadata Apple-specific
Why convert MOD to CAF?
Converting makes sense where the strengths of CAF meet what MOD cannot give you. 64-bit offsets — no size ceilings Meanwhile 31 8-bit samples max in classic MOD One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this MOD to CAF converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for MOD to CAF?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Will converting MOD to CAF reduce audio quality?
If CAF is lossless, the output contains everything the MOD file contains — no further loss is added. If CAF is lossy, one recompression pass is unavoidable; the quality slider controls how much. Loss that already happened in the source file can never be undone by converting.
Are tags like title and artist preserved?
Tag handling varies between target formats and this conversion focuses on the audio itself. For archival copies where tags matter, keep the original file; the converted copy is for playback and sharing.
