Free online IT to MP3 converter

Source format: IT

IT is a tracker module format used by Impulse Tracker and compatible music players. It stores song data such as patterns, instruments, samples, effects, and playback instructions rather than a finished audio stream. IT files are common in the demoscene, retro game music, and tracker-based composition workflows. Because they are module files, they can sound different depending on the player and the sound library used.

Target format: MP3

MP3 is a widely supported compressed audio format designed for efficient storage and playback. It is ideal for sharing music, streaming, portable devices, and general compatibility across operating systems and media players. Compared with tracker modules, MP3 is a fixed audio recording, so it does not preserve editable patterns or instrument data, but it is much easier to play everywhere.

How to perform the conversion

The most reliable way to convert IT to MP3 is to first render the module to audio and then encode that audio to MP3. A good desktop option is foobar2000 with the appropriate decoder components, or a tracker/player such as OpenMPT for rendering, followed by an audio encoder like FFmpeg. If you want a simple browser-based workflow, you can convert the file on 101convert.com for free without installing any software.

Using OpenMPT:

1. Open OpenMPT and load the .it file.
2. Check that the module plays correctly and that the sample rate and channels are set as desired.
3. Choose File → Export → Wave or the equivalent render/export option.
4. Save the output as a .wav file.
5. Convert the WAV to MP3 with FFmpeg using a command such as ffmpeg -i input.wav -codec:a libmp3lame -q:a 2 output.mp3.

Using foobar2000:

1. Install foobar2000 and any needed module decoder support.
2. Add the .it file to the playlist.
3. Select the file and choose Convert → ....
4. Pick MP3 as the output format and set the desired bitrate or quality.
5. Start the conversion and save the resulting .mp3 file.

Using 101convert.com:

1. Upload the .it file to the converter.
2. Select MP3 as the target format.
3. Start the conversion and download the finished .mp3 file.

Notes on quality and limitations

IT to MP3 is a lossy conversion: the resulting MP3 will not retain tracker editability, instrument separation, or pattern data. The final sound depends on the player or renderer used, because tracker modules may rely on specific playback behavior, effects, or interpolation settings. For best results, render at a high sample rate and use a high-quality MP3 setting to reduce artifacts. If the module uses unusual effects or relies on exact tracker timing, different software may produce slightly different audio. If you need an archival copy, keep the original .it file as well as the exported .wav or .mp3.
