How to Extract Audio from a Video (and Save It as MP3)

August 30, 2026

When you need just the sound

Sometimes the video part isn't the point. You recorded a lecture, a meeting, a podcast-style conversation, a voice memo as a video, or a song playing in the background of a clip, and what you actually want afterward is the audio on its own, as a normal MP3 you can play anywhere. People describe this in different ways: extract audio from a video, take the audio from a video, pull the sound or the music out of a video, convert a video to MP3. It is all the same job.

How to extract audio from a video in four steps

1. Open FileWizy's audio extractor.
2. Drop in your video, or click to choose it. MP4, MOV, WebM and most common formats work.
3. Click Extract audio and wait a few seconds. Short clips are quick; longer ones take a little more.
4. Download your MP3.

Everything runs in your browser. Your video is never uploaded to a server, the original file is not changed, and there is no account to create. Videos up to about 200 MB work, depending on your device's memory.

What you get

You get a standalone MP3, which plays on virtually any phone, computer, car stereo or speaker. It is also far lighter than the video it came from, because the picture, which is most of the data, is left behind. That makes it easy to share, attach to an email or upload to a platform that only accepts audio.

MP3 is a compressed format, so start from the best-quality video you have. If you later need another format such as WAV, OGG or M4A, convert the MP3 with the audio converter; our guide to MP3, WAV, OGG and M4A explains which one to choose.

Common situations

• A lecture, class or meeting. Extract the audio so you can listen on the go. If it is long, trim the video first so you only process what you need.
• A podcast or interview filmed on video. Pull out the audio and publish it as an episode, or send it to a transcription service.
• Music in your own clips. Keep the sound of a performance you recorded or a track you made, without carrying the video around.
• A voice memo or screen recording. If you captured something with the browser recorders, you can save only the audio.

Cleaning it up afterward

If the extracted audio came from a phone recording and sounds quiet or muffled, FileWizy's audio enhancer can normalize the volume and apply a quick EQ pass tuned for voice or music. If you only need part of the recording, the audio trimmer lets you cut the MP3 to the exact section, and the video trimmer does the same before extracting. For a longer clip you want to shrink first, see how to compress a video.

If something goes wrong

The MP3 is silent. The video itself may have no audio track, or the sound was muted when it was recorded. Play the original to check.

The file is too large. Videos beyond roughly 200 MB can exceed what a browser can hold in memory. Trim the video to the part you need, then extract.

It takes a while. Processing happens on your device, so a long video on an older phone will be slower than on a computer. Close other tabs and try again.

The sound is poor. Extraction cannot improve a bad recording. Use the audio enhancer to even out the volume, but for important material re-record in a quiet place.

A quick note on rights

Extracting audio from a video you don't own the rights to, like pulling the soundtrack off someone else's video, isn't something this tool exists to enable responsibly; it's meant for your own recordings, interviews, voice memos and similar content, or material you have permission to use.

The short version

Drop the video in, click extract and download the MP3. It runs in your browser, nothing is uploaded, and you can clean up, trim or convert the result with the other tools afterward.
