Audio Converter

Convert audio files to MP3, WAV or FLAC: drop one or many — MP3, M4A, WAV, FLAC, OGG, Opus or WebM — choose the format and, for MP3, the quality, and save them one by one or in a ZIP. Your files are processed on your device and never uploaded; it's free and needs no sign-up.

MP3 plays everywhere, at 128 to 320 kbps. WAV keeps every sample uncompressed, for editing; FLAC keeps every sample in about half the size. M4A and AAC files are decoded by your browser itself.
