How to extract audio from video — free, no install, no upload

You recorded something — an interview, a lecture, a live performance, a voice memo shot on your phone — and all you need is the sound. The video file is just in the way. Extracting audio from a video used to mean downloading software, converting formats, and hoping nothing went out of sync. It does not have to work that way anymore.

This guide shows you how to extract audio from a video using a browser tool that runs entirely on your device — no install, no account, no file upload. It also covers every platform: Mac, iPhone, Windows, and Android. Whatever you are working with — an MP4, MOV, WebM, or anything else — there is a straightforward path to getting the audio out.

Why extract audio from a video?

The use cases are more varied than you might expect:

Podcast clips. Pull a compelling segment from a recorded interview or panel. Trim it, export as MP3, and publish it as a standalone audio clip or podcast episode without re-recording anything.

Removing or replacing music. If your video has a copyrighted soundtrack, extracting the audio lets you work with it separately — mute the music track, replace it with something royalty-free, or isolate a voice recording buried under music.

Dubbing and localization. Strip the original audio to create a clean base for dubbing into another language or adding a different voiceover.

Archiving recordings. Lectures, conference talks, meeting recordings — often the visual information is redundant. An audio file is a fraction of the size of a video and easier to store, search, and play back.

Repurposing for audio platforms. A video posted to YouTube or social media can have its audio extracted and submitted to Spotify, podcast apps, or audio archives with no re-recording required.

How to extract audio from a video (the quick way)

The fastest way to get audio from a video file is the browser tool at privateconvert.org. It runs entirely in your browser using local processing — your video file never leaves your device and nothing is sent to a server. That matters when the footage contains sensitive content: a confidential meeting, medical information, private conversations, or footage with people who have not consented to it being shared with a third party.

Here is how to extract audio from a video online, for free:

1. Go to the Extract Audio tool at privateconvert.org.
2. Drag your video file onto the tool, or click to browse. Any common format works — MP4, MOV, AVI, WebM, MKV.
3. Choose your output format: MP3 for broad compatibility and smaller file size, WAV for lossless quality.
4. Click Extract. The audio is processed locally in your browser.
5. Click Download. The audio file saves directly to your device.

There are no watermarks, no file-size caps, no sign-up prompts, and no subscription required. Because the processing happens on your machine rather than a server, extraction is often faster than upload-based tools — especially for large video files on a slow connection.

This is the most private and most straightforward way to extract audio from a video online free.

How to extract audio from a video on Mac

QuickTime Player (built into macOS)

QuickTime’s export function is the simplest native option on Mac. It does not give you full control over format or bitrate, but it works without installing anything:

1. Open your video in QuickTime Player.
2. Go to File → Export As → Audio Only.
3. Choose a save location and click Save.

QuickTime exports as M4A (AAC). This plays fine in most media players and podcast apps. If you need MP3 specifically, you will need to convert afterward — or use the browser tool instead.

iMovie

iMovie lets you detach the audio track and export it independently:

1. Import your video into iMovie and add it to a new project timeline.
2. Right-click the clip in the timeline and choose Detach Audio.
3. Delete the video track if you only want the audio.
4. Go to File → Share → File. Under Format, choose Audio Only, then set the format to MP3 or AAC.
5. Click Next, name the file, and save.

Browser fallback on Mac

If you want MP3 output without the extra steps in iMovie, open Safari or Chrome and use privateconvert.org. It handles format selection in a single step and keeps the video file local — nothing leaves your Mac.

How to extract audio from a video on iPhone

Using iOS Shortcuts

iPhone does not have a built-in audio extractor, but the Shortcuts app (pre-installed on iOS 13 and later) can handle it:

1. Open Shortcuts and tap the + button to create a new shortcut.
2. Search for and add the action “Encode Media.”
3. In the action settings, set the format to MP3 (or M4A) and check “Audio Only.”
4. Add a “Get File” action at the top to select your video, and a “Save File” action at the end.
5. Run the shortcut, select your video when prompted, and save the exported audio.

This works well but takes a few minutes to set up the first time.

iMovie for iPhone

The iPhone version of iMovie supports audio export:

1. Create a new project and import your video.
2. Tap Done when you have it in the timeline.
3. Tap the Share icon and choose Save Video.

Note: iMovie for iPhone does not export audio-only directly. You get a video file with only audio content, which you would then need to convert separately.

Browser tool in Safari on iPhone

The cleanest option on iPhone: open Safari, go to privateconvert.org, load your video from your Camera Roll or Files app, choose MP3, and download the audio file. The video stays on your device throughout. This is particularly useful for extracting audio from sensitive footage — personal calls recorded as video, private conversations, or anything you would not want uploaded to a cloud service.

How to extract audio from a video on Windows

VLC Media Player (free)

VLC is the most reliable free option on Windows for extracting audio from MP4 and other formats:

1. Open VLC and go to Media → Convert/Save.
2. Click Add and select your video file, then click Convert/Save.
3. In the Convert dialog, click the profile dropdown and select Audio — MP3.
4. Click the wrench icon next to the profile to verify the codec settings if needed.
5. Set a destination file name and click Start.

VLC processes the file locally and outputs the audio track. The interface is not the most intuitive the first time, but it works reliably on any Windows version.

Clipchamp (built into Windows 11)

Clipchamp is Microsoft’s built-in video editor and handles basic audio work, but it has a significant limitation: it does not export audio-only files. You can mute the video track and work with the audio layer, but the final export will still be a video file. It is not a practical audio extractor.

Online fallback on Windows

Open Edge or Chrome, go to privateconvert.org, load your video, and download the audio file. No install required, and the video file never leaves your machine. This is the simplest path if you want MP3 output without configuring VLC’s export settings.

How to extract audio from a video on Android

Google Photos

Google Photos does not have a direct audio extraction feature. It is primarily a viewer and organizer, not an audio tool.

Free apps from the Play Store

Apps like MP3 Video Converter or Video to MP3 Converter handle the conversion on-device. Open the app, select your video, choose the output format, and export. The quality varies by app and most show ads in the free tier. Check permissions and reviews before granting media access to any app you are not familiar with.

Browser tool in Chrome on Android

The most straightforward option with no app install: open Chrome, go to privateconvert.org, select your video from local storage, choose MP3 or WAV, and download the audio file. Touch interaction works well on Android. The video is processed locally in the browser — nothing is sent to a server, which matters if the footage is personal or contains people who have not consented to it being shared.

MP3 vs WAV — which audio format to choose

When you extract audio from a video, you will typically choose between MP3 and WAV. Here is when to use each:

	MP3	WAV
File size	Small (compressed)	Large (uncompressed)
Audio quality	Very good at 192–320 kbps	Lossless, no quality loss
Compatibility	Works everywhere	Works everywhere
Best for	Sharing, podcasting, streaming	Editing, archiving, post-production
Editing flexibility	Loses quality with each re-encode	Re-encode without degradation

Recommendation: Use MP3 if you are sharing the audio, posting it online, or sending it to someone. Use WAV if you plan to edit the audio further — mix it, add effects, or combine it with other tracks — because WAV files do not degrade with repeated re-encoding the way compressed formats do.

At 192 kbps, MP3 audio extracted from a typical video is indistinguishable from the source in most listening contexts.

Frequently asked questions

Does my video get uploaded to a server when I extract audio? Not with privateconvert.org. The tool runs entirely in your browser and processes the file locally on your device. The video is never transmitted anywhere. Most online audio extractors do upload your video to their servers for processing — a real privacy concern for sensitive footage. With privateconvert.org, the privacy guarantee is structural: there is no server to receive the file.

Can I extract audio from a video for free? Yes. The browser tool at privateconvert.org is free with no file-size caps, no watermarks, and no account required. VLC on Windows and QuickTime on Mac are also free. The iOS Shortcuts approach requires no paid software.

What video formats does the browser tool support? MP4, MOV, WebM, AVI, MKV, and most other common video container formats. If you can play it in a browser, the tool can extract its audio.

Can I extract audio from an MP4 file specifically? Yes. MP4 is the most common case. All of the methods covered here — the browser tool, VLC, QuickTime, iMovie — handle MP4 without any issues. The audio track in an MP4 is typically AAC, which the browser tool can re-encode to MP3 or WAV on output.

Will the extracted audio be out of sync with the original video? No, if you are extracting the full audio track. The audio extracted from a video is a direct copy of the audio stream — no re-timing is involved. Sync problems only arise when you are trying to re-combine audio with a separate video track after editing.

What if the extracted audio file is silent? This usually means the video file has no audio track, or the audio track is in a format that could not be read. Try playing the original video with sound to confirm audio is present. If it plays with sound, try a different output format — for example, WAV instead of MP3.

Can I extract just a portion of the audio, not the full file? The Extract Audio tool at privateconvert.org currently extracts the full audio track. To get a specific segment, extract the full audio first, then trim it using any audio editor — Audacity (free, desktop), GarageBand (Mac or iPhone), or an online audio trimmer.
