How do I convert FLAC to GSM using this tool?

Upload your FLAC file by clicking the file picker. Make sure the output format is set to GSM. Optionally, adjust the sample rate or bitrate if your target system requires it (GSM is typically fixed at 8kHz/13kbps). Hit 'Convert', wait a few seconds, then download your new GSM file. No software installation is needed.

Why should I convert FLAC to GSM instead of keeping the FLAC file?

FLAC is lossless and preserves audio perfectly, but files are large. GSM is a low-bitrate codec (13kbps, 8kHz) built for voice telephony. Converting shrinks a 30MB FLAC track to roughly 1MB, making it ideal for voicemail, auto-attendants, IVR menus, or legacy mobile phones that only support GSM voice.

What technical changes happen during FLAC to GSM conversion?

The converter downsamples the FLAC file to an 8kHz mono PCM signal and re-encodes it with the GSM full-rate codec. All frequencies above 4kHz are removed, and stereo channels are merged to mono. Any metadata like album art or tags is lost because the GSM container doesn't support it. The result is speech-optimized audio with much lower bitrate.

Is FLAC-TO-GSM free to use?
