Extract audio from any video

Recorded a lecture, interview, podcast, DJ set, sermon or voice memo as video and only need the sound? VidShift's video to MP3 converter pulls the audio track out of any common video container - MP4, MOV, MKV, WebM and more - and saves it as a standard MP3 that plays on every phone, car stereo, smart speaker and music app. It is the quick way to turn a screen recording of a meeting into a file you can listen to on the commute, or to lift the soundtrack from a clip you want to reuse.

Choose the bitrate that suits you: 128 kbps for the smallest files when the source is speech, 192 kbps as a balanced default for most content, or 320 kbps for the highest MP3 quality when the audio is music and you want it to sound its best. There is no point setting a bitrate higher than the source, so options above your file's original quality are hidden automatically.

Prefer to keep the original audio untouched? Select Match source to copy the existing bitrate rather than re-encoding, or export to AAC, WAV or FLAC when you need a lossless file or a specific format instead of MP3. Whatever you pick, only the audio is processed, so extraction is far quicker than a full video conversion.

Everything runs in your browser, so even a two-hour recording is processed without uploading a single byte. That keeps your audio private, removes any file size cap, and means there is no waiting on a slow upload before the work can start. If you specifically have an MP4, our dedicated MP4 to MP3 converter targets that format directly.

Why Extract Audio from Video?

Every container, one audio extractor

Video arrives in whatever container the device that recorded it happens to write. A Mac screen recording is a .mov, a Twitch VOD is a .mkv or .ts, a browser recording is a .webm, a phone clip is a .mp4 or .m4v, and a camera export could be any of them. This page reads all of them, so you do not have to work out what your file is before you can get the sound out of it. Drop it in, and the audio track is decoded locally and written to the format you choose.

Apple ProRes .mov files from Final Cut, Premiere or DaVinci Resolve are handled too, which matters because most browser-based tools cannot decode ProRes at all. The relevant decoder is fetched only when a file actually needs it, so nothing extra is downloaded for an ordinary MP4 or WebM.

What people use it for

Podcasters convert recorded interviews, livestreams and video calls into MP3 episodes ready for Spotify, Apple Podcasts or a private RSS feed. Musicians and DJs pull the sound off concert footage and live sessions to listen on the move or sample in a DAW. Content creators lift clean voiceover takes out of screen recordings and reuse them in a different edit without re-recording. Students and researchers strip the audio from lectures, webinars and conference talks so they can listen on a commute or run the file through a transcription tool. Language learners do the same with films and interviews, dropping the audio onto a phone or smart speaker for repeated listening.

There is a practical reason too: audio is dramatically smaller than video. A two-hour talk that fills 1.5 GB as a video file lands under 100 MB as an MP3, which is the difference between a file you can email and one you cannot.

No upload, no size cap, no software

Most online audio extractors work by uploading your video to a server, converting it there and handing back a download. That means a copy of your recording sits on hardware you do not control, and it means a queue, an upload wait and a file size cap. VidShift does none of that: the conversion runs inside your browser using WebAssembly and WebCodecs, so the video never leaves your device. Nothing is installed and no account is created. The page is cached on your first visit, and each audio codec is cached the first time a conversion actually uses it, so once you have run a conversion that same job works offline afterwards. That makes it safe for confidential interviews, internal meeting recordings, unreleased music and anything else you would not hand to a stranger - and faster for large files, because there is no upload to sit through first.

Frequently Asked Questions

What quality is the MP3?

The default is 192 kbps, a good balance of size and quality. You can select up to 320 kbps for the highest quality, or 128 kbps for a smaller file.

Can I keep the original audio quality?

Yes. Choose Match source to copy the existing bitrate, or export to AAC, WAV or FLAC if you need a lossless or specific format rather than MP3.

Which video formats can I extract audio from?

Any common container, including MP4, MOV, MKV, WebM and more. The audio track is decoded in your browser and written out as MP3.

Are my files uploaded?

No. The audio is extracted entirely in your browser using WebAssembly, so your video never leaves your device.

How do I extract audio from a video without installing software?

Open this page, drop your video in and click Extract Audio. There is nothing to install, no extension to add and no account to create - the whole conversion runs inside your browser using WebAssembly and WebCodecs. The page itself is cached after your first visit, and once you have run a conversion the codec it needed is cached too, so the same conversion works offline from then on.

Can I extract audio from MOV, MKV or WebM files?

Yes. Every common container works, including MOV (with Apple ProRes), MKV, WebM, OGV, M4V, MPEG and MPEG-TS. The audio track is decoded regardless of the container it arrived in. If your file is specifically an MP4, the MP4 to MP3 converter covers that pairing in more detail.

Can I extract audio from several videos at once?

This page handles one video at a time. For a folder of files, the batch converter queues them all and writes every one to a single chosen audio format, still without uploading anything.

Is there a file size limit?

No. There is no upload, so there is no server-side cap - the practical limit is your device's memory. Only the audio track is processed, so even multi-gigabyte recordings extract comfortably.

Does it work on iPhone, Android and Chromebook?

Yes. It runs in any modern browser with WebAssembly and WebCodecs support, which covers recent Chrome, Edge, Safari and Firefox on iOS, Android, macOS, Windows, Linux and ChromeOS. Extracting audio is far lighter than transcoding video, so older phones handle it fine.

Is this video to MP3 converter really free?

Yes. There is no cost, no signup, no daily limit and no watermark on the audio. Conversion runs on your own device rather than on paid servers, so there is nothing to charge for.
