Why use Aback Video for this

  • Lossless copy when possible

    Most MP4 and MOV videos carry AAC audio. Choosing M4A copies that track exactly, with no quality loss and almost no wait.

  • Six formats

    MP3 for compatibility, M4A for Apple devices, WAV and FLAC for editing, OGG and Opus for small files.

  • Bitrate choice

    From 320 kbps for music down to 64 kbps for voice notes.

  • Stays on your device

    The audio is extracted in your browser. The video is never uploaded.

Frequently asked questions

Can I do this on my iPhone?

Yes. Open this page in Safari, tap the drop zone and choose the video from Photos or Files. The MP3 is saved to your Downloads folder in Files.

Is M4A better than MP3 for iPhone videos?

iPhone videos store AAC audio, so choosing M4A copies it without any loss. MP3 re-encodes it but plays on more old devices.

Which format gives the best quality?

M4A, when the video's audio is AAC, because it is copied without re-encoding. WAV and FLAC are also lossless copies of the decoded sound but larger. MP3 at 192 or 320 kbps is very close and plays everywhere.

Can choosing 320 kbps improve the original sound?

No. Re-encoding can only keep or lose detail, never add it. If the video's audio is 128 kbps AAC, a higher MP3 bitrate just makes a larger file.

Is my video uploaded?

No. The audio is extracted by FFmpeg running inside your browser.

Can I extract only part of the audio?

Extract the whole track here, then cut it with Audio Cutter, which also adds fades.

What if the video has no sound?

You will see a message that no audio stream was found, instead of an empty file.

Can I do this on my phone?

Yes, in Safari and Chrome. MP3 extraction from a long video takes a little longer on phones; M4A copy is instant.
