About this launch

audioutils.com, as visitors see it

AudioUtils is a free, browser-based audio converter that transforms audio files entirely on your device without uploading anything to servers. It converts MP3, WAV, FLAC, OGG, M4A, AAC, WMA, AIFF, Opus and supports video-to-audio extraction from MP4 and MOV files.

The service uses FFmpeg compiled to WebAssembly, allowing all processing to happen locally in your browser. This means files never leave your device, there is no install or plugin required, and conversion works offline once the page loads. It functions across Mac, Windows, iPhone, Android, and Linux on any modern browser.

AudioUtils offers a free tier with 5 conversions per month limited to 10-second previews, plus paid Pro plans (weekly, monthly, and yearly) that unlock unlimited full-length conversions and 500MB file size limits. The yearly plan provides the best value at $5 per month when billed annually.
