Video to MP3 and extract audio
Pick a format, then Download. Trim to keep just a part.
It all happens in your browser, so even a big video doesn't wait on an upload. Works on files you have. Extractune doesn't download from YouTube or links.
How it works
- 01
Drop your video in
An MP4, MOV, WebM or MKV, from your camera roll, a download, or an export from your video editor. Drop it on the tool at the top of this page, or tap Choose a file. Up to 500MB and 20 minutes.
- 02
It converts right there
The sound comes out in your browser while you watch. Nothing is uploaded, so even a big file doesn't wait.
- 03
Download the MP3
The Download button is already on MP3, and the format beside the tool (the Convert tab on phones) switches it to MP3, WAV or WebM. Only want part of it? Tap Trim and extract first.
What people use it for
- Keep the song from a concert video you filmed.
- Listen to a recorded talk or lecture on the go, with the screen off.
- Turn a screen recording into a voice memo.
- Pull the audio of an interview to edit or transcribe.
- Get the sound of a clip for your own edit.
Inside an MP4: which videos work, and when to pick WAV
MP4 is what most Android phones, cameras, screen recorders and video editors save. Inside, the picture is usually H.264, HEVC or AV1, and the sound is almost always AAC. Only the sound is read: the picture is skipped, so a 4K or HDR video converts as quickly as a small one of the same length.
AAC and MP3 are both compressed, so turning one into the other re-encodes the sound. For listening you won't hear it. If you're going to edit the audio and save it again, download WAV instead, so each save doesn't compress it once more.
WAV stores sound uncompressed, and every music and video app opens it, including GarageBand, FL Studio, Ableton, Premiere and samplers. The cost is size: about 11.5MB a minute in stereo, against roughly 2.4MB for MP3. Extractune's WAVs are 16-bit at 48kHz, the usual rate for video work. A WAV can't sound better than the sound inside the MP4: it keeps what's there, so later edits don't make it worse, but it doesn't bring back what the video's own compression took out.
Some MP4s carry more than one sound track, like a second language or a commentary. You get the main one, the track a video player starts with.
Other videos work the same way, as long as your browser can open them: MOV from iPhones and cameras, WebM from browser and screen recordings, and MKV on a computer or an Android phone. Audio files work too (MP3, WAV, M4A, FLAC, OGG and AAC), if you only want to trim one or change its format.
Older formats like AVI, WMV and FLV don't open in any browser, so Extractune can't read them. On a computer, the free VLC player can convert one to MP4 first (Media, then Convert / Save); then drop the MP4 here.
Some sound can't be decoded in a browser even when the video itself opens: Dolby Digital and DTS, which are common in movie files. Extractune names the format when that happens, and when the file also has a stereo track it can play, it uses that one instead.
Questions
How do I convert a video to MP3?
Drop the video on the tool at the top of this page, or tap Choose a file. The sound comes out right in your browser, and the Download button is already on MP3. To keep only part of it, tap Trim and extract.
How do I convert MP4 to WAV?
Drop the MP4 on the tool at the top of this page, then pick WAV beside the tool (the Convert tab on phones) instead of MP3. WAV is the format to edit in, since nothing more is lost each time you save.
Can I get each instrument as its own WAV?
Yes. On the stem splitter, split the song, pick WAV and tap All 4 parts: the voice, drums, bass and everything else, each as its own WAV, in one zip.
What's the difference between MP3 and MP4?
MP3 is a sound-only file. MP4 is a container that holds video, sound and sometimes subtitles together, and the sound inside is usually AAC. Converting MP4 to MP3 keeps only the sound, so the file is far smaller and plays on anything that plays music.
Do I need to download or install anything?
No. The converter runs in your browser on any phone or computer, so there's no program or app to download: the only download is your MP3. Bookmark the page, or add it to your home screen, to open it like an app next time.
Can I convert an M4A to MP3 too?
Yes. An M4A is an MP4 with only sound in it. Drop it the same way and download it as MP3.
What if the video has no sound?
Some videos, like many screen recordings, have no audio track at all. Extractune tells you so as soon as you drop it in, instead of handing you a silent MP3.
Can I paste a YouTube link?
No. Extractune only works with video files on your device, never links. Saving videos from YouTube and similar sites breaks their terms, and usually the rights of whoever made them. If it's your own upload, download it from YouTube Studio first, then drop the file here.
What quality is the MP3?
Good for listening on any phone, car or speaker. If you're going to edit the audio in a music or video app, download it as WAV instead: it's larger, but nothing more is lost when you edit it.
Does my video get uploaded?
No. The conversion runs in your browser, so the file never leaves your device, and a big one doesn't wait on an upload.
Is it free?
Yes. No sign-up, no watermark, and no limit on how many files you convert to MP3.
