AudioUtils

AudioUtils is a free online audio converter built for private, local conversions. Select an audio file (or a supported video), choose an output format, and download the converted result—no signup and no email gate.

Conversion runs entirely 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, and Opus, with video-to-audio extraction supported for MP4 and MOV.

With a library of 77 converters organized by common audio formats and directions, you can handle publishing/export needs, editing workflows, compatibility fixes, and extracting audio tracks from screen recordings or clips—all without installing software or browser plugins. The free tier provides 10-second preview output, while Pro unlocks full-length conversions and higher file size limits.
