MOD to OPUS Converter
Processing entirely on your device — large files may take a moment.
Opus delivers the smallest files with the best quality for streaming and messaging. If your files are still in MOD format, this page is the shortcut: 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.
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.
+ 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 OPUS format
Opus (IETF RFC 6716, 2012) is the codec that ended the argument: it merges Skype's CELT and Xiph's SILK into one royalty-free format that is simultaneously the best low-latency speech codec and a superb music codec. WebRTC calls, Discord, WhatsApp, WhatsApp calls, YouTube's low-bitrate streams and Zoom all run on it.
At 6 kbps it keeps speech intelligible; at 128 kbps it is transparent for music; latency can dip below 5 ms for live conversation. Its weakness is hardware: dedicated chips and some car/hi-fi devices still lack it, and standalone .opus files are less recognized than MP3 on random devices.
+ Strengths
- ✓Best quality-per-bit across speech and music
- ✓Ultra-low latency — built for live calls
- ✓Royalty-free IETF standard
! Limitations
- −Hardware support still incomplete
- −Not a mastering or archival format

Frequently asked questions
Is this MOD to OPUS 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 OPUS?
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.
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.
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.
