Video to AAC
Extract the audio track from a video as an AAC file.
Extract the audio from a video: pull the audio track out of a video and save it as a standalone AAC file at 192kbps, the codec used natively inside most MP4 videos. AAC generally sounds better than MP3 at the same bitrate, and plays on effectively every modern phone, computer and media player.

How to use Video to AAC
Two steps, and nothing to install.
Drop your video file
Add an MP4, MOV, MKV, WEBM or AVI file. Nothing is uploaded.
Download the AAC file
Save the audio track as a standalone 192kbps file.

How this works in your browser
The video stream is discarded outright and only the audio is processed, which is why extraction is far quicker than any video conversion. The audio is decoded from whatever the source used and re-encoded with the AAC codec at a constant 192kbps, then written into a raw AAC stream format that players recognise as a standalone audio file. Worth being precise about: because the encode is explicit rather than a stream copy, an MP4 that already contained AAC still gets re-encoded, adding one lossy generation. That is a deliberate simplicity trade, since it guarantees a consistent, predictable output file regardless of what the source container happened to hold.
Video to AAC vs. upload-based online tools
| Feature | Video to AAC (in-browser) | Upload-based online tools |
|---|---|---|
| File upload required | No - never leaves your device | Yes - file is sent to a server |
| Processing queue | None - starts instantly | Often, especially at peak times |
| Watermark on output | Never | Common on free plans |
| Usage limits | None - free, unlimited use | Often capped per day or file size |
| Works offline once loaded | Yes, for most tools | No - requires a live connection |
| Account required | No | Often, for anything beyond a trial |

Frequently asked questions
What it can and cannot do, and what happens to your files.
Why choose AAC over MP3?
AAC generally delivers better audio quality than MP3 at the same file size, and is the native format inside most MP4 files.
Is AAC widely supported?
Yes, AAC plays natively on virtually all modern phones, computers, and media software.
Does this just copy the audio out of my MP4?
No. Even though most MP4 files already contain AAC audio, the track is re-encoded at 192kbps rather than copied. That means one additional lossy generation, which is not audible in normal listening but is worth knowing if you are chaining conversions.
What bitrate do I get?
A constant 192kbps, which is comfortably transparent for speech and generous for most music. There is no quality selector, so the result is predictable rather than adjustable.
Should I extract AAC or MP3?
AAC if the file is for your own listening or for modern devices, since it sounds better at the same size. MP3 if it needs to work with older hardware, car stereos or software that predates widespread AAC support, which remains the one thing MP3 still wins on.
Is my video uploaded anywhere?
No. The extraction and re-encode both run inside your browser tab.
