Is AAC better than MP3?

At the same bitrate, AAC generally produces cleaner-sounding audio thanks to a more efficient, modern compression design. Both are widely supported, but AAC is the default for Apple devices, YouTube, and most modern streaming audio.

Why is extracting AAC from an MP4 so fast?

MP4 files already carry AAC audio internally in most cases, so extracting it is close to a direct stream copy rather than a full decode-and-re-encode — much faster than converting to a different codec.

What if my video has no audio track?

There's nothing to extract — check the file in a media player first to confirm it actually has sound.

Will the extracted AAC play on all devices?

AAC is supported natively on iOS, Android, modern browsers, and virtually all current media players, though a few very old devices may need MP3 instead.

Does this work with WebM files, which usually use Opus audio?

Yes — FFmpeg decodes whatever audio codec the source carries (Opus, Vorbis, AAC, MP3, PCM) and re-encodes it fresh to AAC regardless of the original.

What is Video to AAC?

Video to AAC extracts the audio track from any common video file and re-encodes it as a standalone AAC file — the efficient, widely-supported codec behind most streaming services, iTunes purchases, and modern mobile recordings. It accepts MP4, MKV, AVI, MOV, and WebM interchangeably, skips video decoding entirely, and encodes the audio at a solid 192kbps bitrate.

AAC generally sounds cleaner than MP3 at the same bitrate thanks to a more modern compression design, and it's the native audio codec inside MP4 containers already — so extracting to AAC from an MP4 source is often a near-lossless remux rather than a fresh re-encode, preserving quality better than converting to a different codec would.

The extraction runs entirely inside your browser via FFmpeg WebAssembly, so nothing is uploaded during processing.

Need the broadest compatibility instead? Extract Audio from Video outputs MP3, and Video to M4A wraps AAC audio for Apple's ecosystem specifically.

How It Works

FFmpeg reads the video container, applies -vn to skip the video stream, and encodes the audio to AAC at 192kbps. When the source is already MP4 with AAC audio, this is close to a direct stream copy rather than a full re-encode, which keeps quality loss to a minimum.
