Audio Converter FAQs

MP3 plays everywhere and is the safe default. WAV is uncompressed and best for editing. OGG is open and efficient. M4A (AAC) is ideal for Apple devices.

About this tool

Audio comes in more formats than any device supports: a voice memo in M4A, a song in FLAC, a clip in OGG, an old recording in WAV. Audio Converter moves your sound between MP3, WAV, OGG and M4A in your browser — no upload, no signup, no software. MP3 remains the universal choice that plays on every phone, car and speaker; WAV is the uncompressed original for editing; OGG is the efficient open alternative; M4A is the natural fit for Apple devices. Drop a video file and it extracts just the audio, which is the quickest way to save a song, a lecture or a voice note out of a clip. Quality follows one rule: converting from a lossless source keeps the best result, while converting between lossy formats loses a little each time — so keep your originals. Because everything runs locally, private recordings stay private. For the everyday format mismatch, it is the free converter that works entirely on your own device.
