GSM to WAV Converter

Convert GSM files to WAV. Free, without uploading.

This tool converts GSM files to WAV. GSM phone audio.

WAV is uncompressed audio: no quality loss, but large files. Editing and recording software use it a lot. WAV is lossless, so the audio keeps the quality it has in the GSM file.

Conversion runs on your device; your file is never sent to a server. The components download once on first use, and later conversions start right away.

How to use

1. Choose the GSM file, drag it in, or paste its link.
2. Choose the audio quality; optionally enter a start and end time.
3. Press "Convert" and download the WAV file.
