WAV is an audio format developed by Microsoft and IBM for storing uncompressed audio data. It’s widely used for high-quality audio recording and editing. WAV files offer excellent sound fidelity and are compatible with nearly all audio software and hardware.
GSM is a lossy audio format optimized for voice compression, often used in telephony. It provides clear speech at low bitrates, making it suitable for phone recordings, VoIP applications, and legacy mobile systems.
Convert your .wav files to .gsm right in your browser — no downloads, no installs. Everything happens securely in the cloud.
We never store your files permanently. Only you can access them, and they’re automatically deleted from our servers within 2 hours.
Turn your WAV files into GSM in just a couple of clicks. No registration, no limits — and it’s 100% free.
