Extract audio from MP4 as AAC
About MP4 to AAC
AAC is the audio format used across Apple devices, streaming services, and modern apps because it sounds good at small file sizes. If you want just the audio from an MP4 in a compact, high-quality form, AAC is an excellent choice. This tool extracts the sound from your video and saves it as AAC.
Upload your .mp4 file and the converter separates the audio and encodes it as AAC, ready for phones, players, and apps that favor it. It runs in your browser, is completely free, and adds no watermark or signup. Your video is used only for the extraction and isn't stored afterward, so your content remains private.
