Free online XM to FLAC converter

Source format: xm

XM is a tracker module format, originally popularized by FastTracker II on DOS. It stores pattern data, instrument definitions, samples, and playback instructions rather than a finished audio waveform. XM files are commonly used by chiptune and demoscene musicians, retro game developers, and anyone working with tracker-based music. Because XM is a sequenced music format, it is compact and editable, but it requires a compatible player or tracker to hear it.

Target format: flac

FLAC stands for Free Lossless Audio Codec. It is an audio format that compresses sound without losing any quality, so the decoded audio is identical to the source waveform. FLAC is widely supported by music players, archival tools, and media libraries. It is a good choice when you want high-quality preservation, smaller file sizes than WAV, and broad compatibility with modern audio software.

How to convert xm to flac

Because XM is not a recorded audio file, the conversion process is really a rendering step: the tracker module must be played back and captured as audio, then saved as FLAC. The most reliable approach is to use a tracker or player that can export audio directly.

1. Open the XM file in a tracker or module player that supports export, such as OpenMPT on Windows or MilkyTracker for playback and rendering workflows.
2. Load the file, then verify that instruments, loops, tempo, and effects sound correct during playback.
3. Use the export or render function. In OpenMPT, choose File → Export → Wave or a similar render option, then export to a temporary WAV file.
4. After rendering to WAV, convert that WAV file to FLAC with a trusted audio tool such as ffmpeg. Example command: ffmpeg -i input.wav output.flac
5. If your tracker can export directly to FLAC, select FLAC as the output format and save the rendered file.

If you want a simple browser-based workflow, you can convert the file on 101convert.com for free, without installing any software.

Notes on quality and limitations

XM to FLAC is not a lossless format-to-format conversion in the usual sense, because XM does not contain final audio. The quality of the FLAC output depends on the player engine, resampling settings, interpolation, stereo separation, and any effects used in the module. Different trackers may render slightly different results if they interpret effects or timing differently.

For best results, use the same tracker or playback engine that the composer intended, render at a high sample rate such as 44.1 kHz or higher, and avoid clipping by leaving headroom during export. If you need an archival master, keep the original XM file as well as the rendered FLAC, since the XM preserves the editable composition data.
