How to convert video to MP3 in three steps

  1. 1

    Add your file

    Drag a video into the upload box, or tap it to browse your device. Files up to 200 MB are accepted.

  2. 2

    Choose the sound quality

    Select 128 kbps, 192 kbps or 320 kbps, depending on how you plan to listen.

  3. 3

    Download the MP3

    Once processing finishes, save the audio straight to your phone or computer.

No installer, no plugin and no editing skills are needed. The whole job happens in your browser.

Formats this video to audio converter accepts

Audiora reads the four containers people record and share most often:

  • MP4: phone recordings, screen captures and most downloaded clips
  • MOV: iPhone and Mac footage
  • WEBM: browser recordings and web video
  • MKV: longer recordings, lectures and gameplay captures

The output is always a standard MP3. That format still plays on more devices than any other audio file, from old MP3 players to smart speakers.

128, 192 or 320 kbps: which should you pick?

Bitrate decides how much detail stays in the audio and how big the final file is. A rough guide:

QualityBest forFile size
128 kbps (Good)Speech, lectures, voice notes, podcastsSmallest
192 kbps (High)Everyday music listening; the default for most peopleMedium
320 kbps (Max)Music you care about, DJ sets, audio you will edit laterLargest

What people turn video to audio for

  • Study on the move: turn a recorded lecture or webinar into something you can play on a commute.
  • Podcast clean-up: strip the audio track from a filmed interview before editing it in Audacity or a podcast app.
  • Music from live recordings: keep the sound of a gig, a rehearsal or a jam session without a heavy video file.
  • Voice memos and meetings: save the conversation, drop the picture, free up storage.

A ten-minute 1080p clip can run to hundreds of megabytes, while the same audio as an MP3 often sits around 10 MB. Converting is one of the quickest ways to clear space on a full phone.

Why use an online MP3 converter instead of software?

Desktop programs work, but they need installing, updating and learning. A browser-based MP3 converter skips all of that. It runs on Windows, macOS, Android and iPhone alike, so you can convert on whichever device the video is sitting on.

Privacy and your files

Your video is used only to create the MP3 you asked for, and it’s deleted from our server as soon as the conversion finishes. We don’t keep the MP3 either, and you don’t need an account. Read our privacy policy.

Frequently asked questions

Is this video to MP3 converter free?

Yes. You can convert without paying and without signing up.

What is the largest file I can upload?

Up to 200 MB per video. For longer recordings, trim the clip first or export it at a lower resolution. The audio will not be affected.

Can I convert video to MP3 on my phone?

Yes. The page works in mobile browsers on Android and iPhone, so there is no app to download.

Will the MP3 sound worse than the video?

At 192 or 320 kbps most listeners can’t hear a difference. MP3 is a compressed format, so for studio editing work keep the original video as your master copy.

Does the video to audio converter keep the full length?

Yes. By default the entire soundtrack is extracted from start to finish. If you only need part of it, enter a Start and End time before converting.

Which formats can I upload?

MP4, MOV, WEBM and MKV.

Can I use it on Mac and Windows?

Yes. It runs in any modern browser, including Chrome, Safari, Edge and Firefox.
