About tool
AudioUtils is a free online audio converter designed for private, local conversions. Pick an audio (or supported video) file, choose your output format, and download the converted result—without uploading your file or creating an account.
Conversions run in your browser using FFmpeg compiled to WebAssembly, so your audio stays on your device. Supported formats include MP3, WAV, FLAC, OGG, M4A, AAC, WMA, AIFF, Opus, plus video-to-audio extraction from MP4 and MOV.
With 77 conversion tools organized across common audio formats and directions, you can switch between formats for publishing, editing, compatibility fixes, or audio extraction from recordings. No install or plugin is required, and it works across modern browsers on desktop and mobile.
Does AudioUtils upload my audio file to a server?

Do I need to install any software or a browser plugin?

Can I extract audio from video files?
