About
AudioUtils is a free browser-based audio converter powered by FFmpeg WebAssembly. All conversion happens locally in your browser tab — no file upload, no server processing, no signup required. Supports MP3, WAV, FLAC, OGG, M4A, AAC, AIFF, OPUS, WMA, and video-to-audio (MP4, MOV). Pro plan removes the preview limit for full-length conversions.
