How do I convert a WAV file to GSM format?

Upload your .wav file using the Choose File button, select 'GSM' as the output format, and click Convert. Once the conversion is complete, a download link for your .gsm file will appear. The entire process runs automatically and takes only a few seconds.

Why should I convert WAV to GSM?

WAV files are large (uncompressed) and not ideal for telephony. GSM is a lossy codec optimized for voice, with a 13 kbps bitrate and 8 kHz sample rate. Converting to GSM reduces file size by about 90% while retaining intelligible speech, making it perfect for voicemail systems, IVR, and embedded applications where storage and bandwidth are limited.

What happens to the audio quality when converting WAV to GSM?

GSM encoding is lossy and forces a fixed 8 kHz mono sample rate at 13 kbps. If your WAV is stereo or has a higher sample rate, it will be downmixed to mono and resampled. The codec removes frequencies outside the voice band, so while it is not a bit-perfect conversion, it is engineered to preserve speech clarity, making it suitable for phone systems.
