Why Use This Audio Converter
Format conversion normally requires desktop software or uploading your files to a third-party service. This converter uses ffmpeg compiled to WebAssembly so every conversion happens right in your browser — fast, free, and completely private.
After converting, explore related audio tools to get more from your files — detect the tempo with the BPM Detector, normalize loudness with the Volume Normalizer, or transcribe a melody with the MP3 to MIDI Converter.
Frequently Asked Questions
Input: any audio format your browser can decode — MP3, WAV, OGG, M4A, AAC, FLAC, WebM. Output: MP3, WAV, OGG, AAC, and FLAC.
No. The ffmpeg engine runs entirely in your browser via WebAssembly. Your files are processed locally and never leave your device.
The first conversion downloads the ~30 MB ffmpeg engine and loads it into your browser. Subsequent conversions on the same page are much faster because the engine stays loaded.
