What Does an Audio Extractor (Video to Audio Converter) Do?
An audio extractor is a video to audio converter: it pulls the soundtrack out of a video file and saves it as a standalone audio file. Drop in a phone recording, a screen capture, a concert clip or a downloaded lecture, and you get the music or sound on its own (a song, a voice memo, a podcast) without the picture.
This one runs completely inside your browser. The video is never uploaded anywhere, there is no file-size queue and no account, and the same engine that powers our Audio Converter handles the encoding, so you get the same seven output formats and quality controls.
How to Extract Audio from a Video
- 1
Open your video
Drop an MP4, MOV, WebM, MKV, AVI or other video file onto the box above, or click it to browse. You can preview the video's sound before you extract.
- 2
Pick an audio format
Choose MP3 for the smallest, most compatible file, WAV or AIFF for editing, FLAC or ALAC for lossless storage, or AAC and OGG for streaming. Adjust the bitrate, bit depth or sample rate if you need to.

Extract and download
Click Extract. The audio is decoded and re-encoded on your own device, then the download button appears. The file keeps your video's original name.
Which Audio Format Should I Choose?
All seven formats come from the same audio track. The difference is how much space they take and where they play.
MP3: share it anywhere
The safe default. Small files that play on every phone, car stereo and messaging app. Pick 320 kbps for near-transparent quality or 192 kbps to keep the file smaller.
WAV / AIFF: edit it
Uncompressed and exact. The format every audio editor and DAW opens instantly. Files are big, but nothing is thrown away. AIFF is the same idea in Apple's container.
FLAC / ALAC: keep it forever
Lossless, roughly half the size of WAV. Perfect for archiving a live recording. FLAC works everywhere except iPhone's stock apps; ALAC is Apple's version for iTunes and Apple Music.
AAC / OGG: stream it
Smaller than MP3 at the same quality. AAC (.m4a) is native on iPhone, iPad and YouTube; OGG Vorbis is the open-source choice used by games and Spotify.

Will the Audio Quality Change?
The extractor can only give you what the video already holds. Most phone videos and downloads store their sound as AAC at 128–256 kbps, so choosing WAV or FLAC will not add detail; it just avoids losing any. Choose a lossless format when you plan to edit the audio, and MP3 or AAC when you just want to listen or share.
Every video's first audio track is used. If your file has several (a commentary track, a second language), we take the first one. The extractor never changes volume, speed or pitch. For that, hand the result to the Pitch Changer or the Audio Cutter afterwards.
Audio Extractor FAQ
Can I extract audio from an MP4 to MP3, or convert a video to audio?
Yes. Drop the MP4 onto the extractor, leave MP3 selected, and click Extract. You can also choose WAV, FLAC, AAC, OGG, AIFF or ALAC instead. The result downloads with the same file name as your video.
Is my video uploaded to a server?
No. The whole process runs inside your browser using a bundled copy of FFmpeg, so the video never leaves your device. That is also why there is no queue and no file-size plan to buy.
Which video formats work?
MP4, M4V, MOV, WebM, MKV, AVI, MPEG, 3GP, FLV, WMV, TS and OGV: practically anything a phone, camera, screen recorder or download produces. Files up to 500MB are supported; trim longer videos first.
Does extracting audio reduce the quality?
Choosing WAV, FLAC, AIFF or ALAC keeps every bit of the video's audio track. Choosing MP3, AAC or OGG re-encodes it, which is fine for listening. Pick the highest bitrate if you want it as close to the original as possible.
Is this audio extractor free?
Yes, completely free. No account, no watermark, no limit on how many videos you extract from. It is supported by the ads on the page.
How do I extract audio from a video on my iPhone?
Open this page in Safari on your iPhone or iPad, tap the box to pick a video from Photos or Files, choose MP3 and tap Extract. There is no app to install. Phones have less memory than laptops, so keep videos to a few minutes or trim them first; if a large file fails, try it in a desktop browser.
Got the audio? Keep going.
Cut it, remove the vocals, or change its key, all in the same browser tab.
