MOD to AC3 Converter
Processing entirely on your device — large files may take a moment.
Amiga Module and Dolby Digital Audio 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. Converting AC3 to MP3 or WAV makes DVD audio tracks usable anywhere.
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.

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.

- ✓Rich demo-scene heritage

About the AC3 format
AC3 (Dolby Digital) is the surround format of the DVD era and still the standard audio track on Blu-rays and broadcast TV. It carries 5.1 channels at 384–640 kbps — built to make home theatre rumble. Extracted from discs or remuxed downloads, .ac3 files are common on everyone's drive.
Phones and most editors do not decode it. The practical move is conversion: MP3 for listening, WAV when the audio is destined for editing. Both keep the mix you know — just in a format every device handles.
+ Strengths
- ✓True 5.1 surround from disc sources
- ✓The DVD/Blu-ray audio standard
! Limitations
- −Almost no mobile or web support
- −Lossy — downmixing loses the surround image

Converting makes sense where the strengths of AC3 meet what MOD cannot give you. True 5.1 surround from disc sources 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 AC3 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 AC3?
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 AC3 reduce audio quality?
If AC3 is lossless, the output contains everything the MOD file contains — no further loss is added. If AC3 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.
Can I convert a whole folder of MOD files?
You can select many files at once and they are processed in a single batch. Output files land in one ZIP download when there is more than one result.
