What is AudioUtils?
AudioUtils is a free online audio converter that works right in your browser. You can turn MP3, WAV, FLAC, OGG, M4A, AAC, WMA, AIFF, Opus, and video files into the format you need without uploading anything. It uses WebAssembly and FFmpeg so the whole conversion happens locally on your device. That means your files stay private, conversions start fast, and you can even use it offline after loading the page. It also includes handy tools like audio cutting, joining, compressing, speed changing, normalizing, and ringtone making. The site offers 77 converters, plus guides that help users choose the right audio format for podcasts, music, voice memos, and video clips.
