XI to OGA Converter
Processing entirely on your device — large files may take a moment.
FastTracker II Instrument and Ogg Audio-Only exist for different jobs: XI is the FastTracker II instrument format — 8/16-bit sample instruments with loop points, carried inside every XM tracker module kit. Converting OGA to MP3 sidesteps the device-support gaps of the Ogg family.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the OGA format
OGA is the Ogg container's audio-only extension: the same Vorbis (or Opus/FLAC) stream as an OGG file, renamed to signal "this is music, not video". Wikipedia's audio files and old game rips commonly use it.
Functionally it is an OGG — and it inherits the same hardware-support lottery. Converting OGA to MP3 ends the guessing game on phones, car stereos and anything without an Ogg decoder.
+ Strengths
- ✓Open, royalty-free Vorbis audio
- ✓Identical quality to OGG
! Limitations
- −Extension confuses players less familiar with Ogg
- −Same hardware gaps as OGG

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