Video to MP3 Converter

Save the sound of a video as an MP3, without uploading it

Sometimes the picture is not the part you want. A recorded lecture you would rather listen to on a walk, an interview you need to send as audio, a song you filmed at a concert. This page opens the video you already have, reads its sound, and writes that sound out as an MP3 that every phone, car and music player can open.

It runs entirely in your browser. The video is read from your own disk and the MP3 is encoded on your device, so nothing is uploaded and there is no queue to wait in. Free, unlimited, no signup, no watermark.

How to use it

1. Add a video. Drop it on the panel above or pick it from your device. One file at a time.
2. Choose a bitrate. 128, 192 or 320 kbps. It starts at 192, which suits most videos.
3. Convert. In Chrome and Edge on a computer you are asked where to save first, and the MP3 is written straight to that file. In other browsers a download button appears when it is done.
4. Watch the progress. The bar shows how much of the sound has been encoded, and you can cancel at any point.

Which files it opens

• Video: MP4, M4V, MOV, MKV and WebM. That covers phone cameras, screen recorders, meeting recordings and most downloads you have saved.
• Audio: M4A, WAV, FLAC, OGG and AAC files can be saved as an MP3 the same way, and an MP3 can be re-encoded at a lower bitrate.
• Not opened: AVI, WMV and FLV files, and videos whose soundtrack is Dolby Digital or DTS. The tool says so by name instead of failing without a reason.

Which bitrate to choose

• 128 kbps for speech: lectures, meetings, podcasts and voice notes. About 1 MB per minute.
• 192 kbps for music and for anything you are not sure about. About 1.4 MB per minute.
• 320 kbps when you want the most an MP3 can hold. About 2.4 MB per minute. It cannot add detail the video never had.

What it does not do

• It does not keep the picture. The video track is skipped, which is also why a long video converts quickly.
• It does not mix several soundtracks. A file with more than one audio track gives you the default one, the track a player picks when you press play.
• It does not trim. The MP3 covers the whole video. To cut parts out first, use the text-based video editor, which can also export an MP3.
• It does not write other formats. The output is always an MP3, in stereo or mono to match the source.

Your video stays on your device

A converter that works by upload has to receive the whole video before it can return a few megabytes of sound, and it holds a copy for as long as its retention policy says. This one has no upload step to begin with. Reading and encoding happen in this tab, no request carries your file anywhere, and closing the page discards everything. That matters for the recordings people most often convert: meetings, interviews, family videos and unreleased work.

Video to MP3 questions

How do I convert a video to MP3?

Choose a video file from your device or drop it on the page, pick a bitrate, and start the conversion. The tool reads the audio track, encodes it as an MP3 and hands you the file. The picture is skipped, not processed, so only the sound is worked on.

Is my video uploaded to a server?

No. Nothing is uploaded. The video is opened by your own browser, the audio is decoded and encoded on your device, and the MP3 is written from the same tab. There is no server step, which is also why there is no queue and no account.

Which video formats can I convert to MP3?

MP4, M4V, MOV, MKV and WebM video. Audio files work too, so an M4A, WAV, FLAC, OGG or AAC file can be saved as an MP3 the same way. AVI, WMV and FLV files do not open. The sound inside the file has to be AAC, MP3, Opus, Vorbis, FLAC or PCM: Dolby Digital and DTS soundtracks, which some MKV films carry, cannot be converted.

Which MP3 bitrate should I choose?

128 kbps is enough for speech, lectures and podcasts and gives the smallest file, about 1 MB per minute. 192 kbps is the default and suits music and most videos at about 1.4 MB per minute. 320 kbps is the highest MP3 quality at about 2.4 MB per minute. A higher bitrate cannot add detail the video's sound never had.

Is there a limit on video size or length?

There is no upload, so there is no upload cap, and the video is read from your disk in pieces instead of being loaded whole. In Chrome and Edge on a computer you choose where to save first and the MP3 is written straight to that file. Other browsers build the MP3 in memory, which allows about five hours at 320 kbps on a computer and about two hours on a phone, and more at a lower bitrate.

Which browsers does the video to MP3 converter work in?

Current versions of Chrome, Edge and Firefox, and Safari 26 or later on Mac, iPhone and iPad. Older Safari versions cannot decode audio inside a page, so the tool tells you to update instead of failing halfway.

Is it really free?

Yes. There is no signup, no watermark, no daily limit and no paid tier for longer files. The work is done by your device, so a conversion costs us nothing to run and there is nothing to charge for.
