WAV (.wav) · Max 20 MB
Most online converters upload your file to a remote server, process it in a queue, then send it back. That round trip takes minutes. AudioUtils skips all of it. The conversion engine runs on your device via WebAssembly.
Speed depends on your device, not your internet connection. A modern laptop converts a 5-minute audio file in 2-3 seconds. Even phones handle it in under 10 seconds. No progress bar that stalls at 99%.
WAV is lossless. Converting to M4A reduces file size at the cost of some audio data. Use a high bitrate to minimize loss. Fast doesn't mean low quality. The encoder uses the same settings as desktop tools like FFmpeg. You get full quality at browser speed.
