Video to M4A converter
Take just the sound out of a video — clips, screen recordings, exports — as an M4A (AAC) file that Apple devices and editors love. Conversion happens in your browser — the file never touches a server.
Loading tool…
An M4A is an MPEG-4 container that holds an AAC audio stream — the same kind of track a typical MP4 video already carries, just without the picture. This tool demuxes the audio out of your video and re-encodes it to a standalone 192 kbps AAC file, so a 200 MB screen recording becomes a small clip you can play, share, or edit on its own. Since most phones, cameras, and export tools already record AAC in the first place, the extracted M4A stays close to what you originally shot, though as a second lossy pass it isn't bit-identical to the source stream.
People reach for a video-to-M4A converter when they only want the sound: a backing track buried in a clip, a voice-over from a screen capture, or a song from a video export headed into a DAW. Extracting to M4A hands you a plain audio track that Logic, GarageBand, or an iPhone library opens directly, with no movie file to strip down first on the other end. And because the decode and encode both run in the browser tab, even a multi-gigabyte export never leaves your device or waits in an upload queue — the practical payoff of in-browser conversion once files get large.

When to use it
- Turn a music video you exported from your editor into an M4A so it lands in Apple Music or GarageBand on your iPhone as a plain audio track.
- Strip the sound from a screen recording of a Suno playback or a livestream you captured, keeping an audio-only file for a voice-memo-style reference library.
- Pull the audio out of a phone video of a rehearsal or jam session and import the M4A into Logic Pro or Ableton as a scratch reference track.
About the M4A (AAC) format
FAQ
The video's audio is already AAC — why re-encode?
Most MP4s already carry AAC, so this re-wraps the track into a standalone M4A and re-encodes to 192 kbps AAC. A second AAC pass is effectively transparent, but it isn't bit-identical to the original stream.
Why choose M4A over MP3?
AAC inside an M4A is a bit more efficient than MP3 at the same bitrate and is the native audio format for iPhones, iTunes, and GarageBand. Pick MP3 instead when you need the widest possible compatibility.
Is an M4A the same thing as an MP4?
They use the same MPEG-4 container, but an .m4a holds only an audio track (AAC or ALAC) while an .mp4 usually carries video plus audio. Extracting to M4A drops the video track entirely, which is why the result is much smaller and opens in music apps as a track rather than a movie.
Will the M4A play on Android and Windows, or only on Apple devices?
AAC inside an M4A is supported far beyond Apple — Android, Windows Media Player, VLC, and every modern browser play it fine. The Apple association just comes from it being the native format for iTunes and iOS; you won't be locked out on other platforms.
Is there a limit on how long or large the video can be?
There's no fixed cap, but because the decode and encode both run inside your browser tab, longer or higher-resolution videos use more memory and take longer to process. A very large file can strain a low-RAM phone or tablet, so for multi-hour recordings a desktop browser is the smoother choice.
