Extract audio from a video
Pull the soundtrack out of an MP4, MOV, WebM or MKV file. When the audio is AAC, Vidmini copies it as it is into an M4A file: no quality loss, done in seconds.
How it works
- 1
Choose or drop the video you want to take the audio from.
- 2
Keep M4A for a lossless copy, or switch to MP3 or WAV.
- 3
Click Extract Audio and download the audio file. Nothing was uploaded.
Lossless by default: the AAC track, copied as it is
Most videos from phones, cameras and editors store their sound as AAC. An M4A file is simply AAC audio in its own container. So when your video's audio is already AAC, Vidmini does not decode and re-encode anything: it copies the audio stream bit for bit into an M4A file. You get exactly the sound that was in the video, and the extraction is near-instant even for long recordings. The result is marked "Lossless: no re-encoding".
If the source audio is something else, such as Opus in a WebM file, it has to be encoded to AAC to fit in an M4A. In that case the result is not marked lossless, and you may as well choose the format that suits you best.
M4A, MP3 or WAV: which one to pick
M4A (AAC) is the best choice when you want to keep the original quality with a small file. It plays in iTunes and Apple Music, on iPhone and Android, in VLC and in most editors.
MP3 is the choice for maximum compatibility: old car stereos, MP3 players, some podcast hosts and web forms that only accept .mp3. You can pick 128, 192, 256 or 320 kbps. It is always a re-encode, so there is a small quality cost.
WAV is uncompressed 16-bit PCM. It is large, around 10 MB per minute of stereo audio, but every audio editor opens it without decoding, and nothing further is lost when you process it. Pick it when the audio goes into a DAW or an editing timeline.
For podcasts, interviews and video editing
Recorded a podcast or an interview on video? Extract the audio to M4A to keep a clean, untouched master, or to WAV to clean it up in Audacity, Reaper, Logic or any other editor. Musicians use it to grab a rehearsal from a phone video; editors use it to pull a camera's scratch track to sync with another recording.
When you only need part of the recording, trim the video first and then extract: with "Continue with this file" the file goes from one tool to the next without selecting it again.
Private and fast on your own device
The video is read by your browser using WebCodecs and WebAssembly; it is never sent to a server. You can check it by going offline once the page is loaded. There is no size limit set by us, and multi-gigabyte files work on desktop browsers.
Frequently asked questions
How do I extract audio from a video without losing quality?
Keep the default M4A format. If the video's audio is AAC, which is the case for most MP4 and MOV files, the track is copied as it is, with no re-encoding and no loss.
What is the difference between M4A and MP3?
Both are compressed audio. M4A holds AAC, which is often what the video already contains, so it can be copied without loss. MP3 is more widely supported by old devices but always requires re-encoding.
Which format should I use for audio editing?
WAV. It is uncompressed 16-bit PCM, opens instantly in any editor and suffers no further loss while you work on it. Export to MP3 or M4A once the edit is finished.
Why is my extraction slower for WebM or MKV files?
Those files often use Opus or Vorbis audio, which cannot be copied into an M4A. Vidmini has to decode and encode the audio, which takes longer than a direct copy.
Does the video get deleted or changed?
No. Your original file is only read, never modified. The extracted audio is a new file you download.
Is my file uploaded?
No. Everything runs in your browser on your device. The page only talks to vidmini.com for its own code, and no tracking cookies are used.
