Extract Audio from Video (Keep Original Quality)
xFormat extracts the audio track from a video in your browser, keeping the original AAC untouched as M4A when possible or converting to MP3, WAV, FLAC or OGG, without uploading the file.

How it works
Need the sound from a video, not the picture? Pull it out here. If the video already contains AAC audio, which is typical for MP4 and MOV, you can save it as M4A with no quality loss. Otherwise pick the format that suits your use.
- 1
Choose the video you want to take audio from.
- 2
Pick an audio format. The tool marks the one that needs no re-encode, such as M4A for AAC audio or OGG for Opus audio.

Click Extract and download the audio file.
Copying versus converting
A video's audio track is already compressed. When it is AAC, the cleanest approach is to copy it straight into an M4A file: nothing is decoded, nothing is re-compressed, so quality is identical and the job finishes almost instantly.
If the track is in some other codec, or you choose another format, the audio is decoded and encoded again. That is fine, but each lossy re-encode costs a little fidelity.
Choosing the output format
M4A (AAC) is best when you want the original sound and a small file. MP3 is the most universal choice for old players and car stereos. WAV is uncompressed, so it is large but ideal for editing in a DAW or video editor. OGG (Opus) is open and efficient, useful for games and some Linux or Android apps, and when the video's audio is already Opus or Vorbis, as in most WebM files, it is copied into OGG unchanged. FLAC is lossless and roughly half the size of WAV.
For MP3, M4A, AAC and OGG you can choose 128, 192 or 320 kbps; the setting is skipped when the track is copied as is. Around 128 kbps is plenty for voice, and 192 to 320 kbps suits music.
Good to know
Videos with several audio tracks give you only the main one. Keep sources under about 500 MB on desktop and 200 MB on phones.
Frequently asked questions
Can I extract audio from a video without losing quality?
Yes, if the video's audio is AAC you can keep it as M4A, and if it is Opus or Vorbis you can keep it as OGG, without re-encoding. Other cases require a re-encode, which may lose a little quality.
What is the difference between M4A and MP3?
Both are lossy, but M4A (AAC) usually sounds better than MP3 at the same bitrate, while MP3 plays on virtually every device.
When should I choose WAV?
Choose WAV for editing or archiving, since it is uncompressed. Note that the files are large, about 10 MB per minute for CD-quality stereo.
Is the video uploaded?
No. The audio is extracted locally in your browser.
Does it work on a phone?
Yes, in mobile browsers. Keep the video under roughly 200 MB on a phone.
