S3M to MP2 Converter
Processing entirely on your device — large files may take a moment.
Broadcast MP2 files convert to MP3 for players that no longer ship the decoder. If your files are still in S3M format, this page is the shortcut: S3M is the ScreamTracker 3 module format — the sound of DOS-era demoscene and shareware-game soundtracks.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the S3M format
S3M is ScreamTracker 3's module format — the 1994 standard that carried PC demo music past the AdLib's FM chip into sampled instruments, with PCM samples, FM instruments or both in one file. Half the classic DOS game soundtracks you remember were S3Ms.
Conversion renders the module through the tracker engine to MP3 or WAV — the FM-vs-sample mix is resolved exactly the way the composer intended, frozen into a universally playable waveform.
+ Strengths
- ✓FM + PCM hybrid instruments
- ✓Iconic DOS-era game soundtracks
- ✓Well-specified, stable format
! Limitations
- −Pattern limits of 1994
- −FM playback differs across engines
- −Adlib-specific quirks may differ
About the MP2 format
MP2 (MPEG-1 Audio Layer II) is MP3's older, simpler sibling — and despite losing the consumer war, it never left broadcasting: digital TV (DVB), DVD-audio tracks and European radio still transmit MP2 daily. Its decoder is trivial, which is exactly why broadcasters love it.
Consumer devices have quietly dropped the decoder, so MP2 files from TV recordings or radio captures need conversion to MP3 for anything portable. The audio itself is often 256–384 kbps — genuinely good quality hiding in a forgotten format.
+ Strengths
- ✓The broadcast standard — still transmitted daily
- ✓Often high bitrate (256–384 kbps)
! Limitations
- −Dropped by consumer players
- −Less efficient than MP3 at equal quality

Frequently asked questions
Is this S3M to MP2 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 S3M to MP2?
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 S3M to MP2 reduce audio quality?
If MP2 is lossless, the output contains everything the S3M file contains — no further loss is added. If MP2 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 S3M 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.
