Audio Extractor

About Audio Extractor

Easily extract audio from your video files with our Free Online Audio Extractor. This tool operates entirely within your browser using the power of FFmpeg.wasm, ensuring your video files remain private and are never uploaded to any server.

Simply upload your video file, select your desired output audio format (MP3, WAV, AAC, or OGG), and click 'Extract Audio'. Preview the extracted audio and download the file directly to your device.

Features:

• Client-Side Processing: Uses FFmpeg.wasm for secure, in-browser audio extraction. Your files stay on your device.
• Multiple Video Formats: Supports common video formats like MP4, WEBM, MOV, AVI, etc. (browser & FFmpeg support dependent).
• Various Audio Outputs: Choose between MP3 (widely compatible, lossy), WAV (uncompressed, lossless), AAC (good quality, lossy), and OGG (open format, lossy).
• Video Preview: Confirm you've uploaded the correct video.
• Audio Preview: Listen to the extracted audio before downloading.
• Direct Download: Get your extracted audio file instantly.
• Easy Sharing: Share the tool using your device's native share options or copy the link.
• Progress Tracking: Monitor the extraction process in real-time.
• Privacy Focused: No file uploads to servers.

How to Use:

1. Load Engine: Wait for the extractor engine (FFmpeg) to load (progress bar shown).
2. Upload Video: Drag & drop your video file onto the designated area or click "Select Video" to browse your device.
3. Preview Video: A preview of your uploaded video will appear.
4. Select Output Format: Choose your desired audio format (MP3, WAV, AAC, OGG) from the dropdown menu.
5. Extract: Click the "Extract Audio" button.
6. Wait & Preview: The progress bar will show the extraction status. Once complete, an audio player will appear allowing you to preview the extracted audio. Errors will be shown in the status area.
7. Download: Click the "Download Audio" button to save the extracted audio file.
8. Share (Optional): Click "Share Tool" to share the link to this extractor.

Note: Processing happens entirely in your browser. Extracting audio from very large video files may take longer and consume more system resources (CPU/RAM).

Quick Answer

To extract audio from a video, upload the file here, choose MP3, WAV, AAC or OGG, and click Extract Audio — the soundtrack is ready to preview and download in seconds. Pick MP3 if you just want a file that plays everywhere, WAV if you are going to edit or master the audio and want no further loss, AAC for the best quality-per-megabyte, and OGG if you need an open format for the web. The extraction runs in your browser through FFmpeg.wasm, so the video never leaves your device, and there is no watermark, no account and no length limit beyond your own memory.

Common Use Cases

Saving music or a soundtrack from a video

Turn a recorded performance, a rehearsal video or a lecture into an audio file you can play in the background or on a phone.

Making a podcast episode from a video recording

Interviews and webinars are often recorded on video; extracting the audio gives you the podcast master directly.

Transcription and note taking

Speech-to-text services generally accept audio and process it faster and cheaper than a full video file.

Grabbing sound effects and ambience

Pull a specific noise, room tone or ambience track out of footage for use in another project.

Listening on the move

An audio-only file uses a fraction of the storage and battery of the original video, which matters for long recordings on a phone.

Editing the sound separately

Extract to WAV, clean it up in an audio editor, then put it back with the Add or Replace Audio in Video tool.

Frequently Asked Questions

How do I extract audio from a video?

Upload the video to this page, select the output format you want from the dropdown, and click Extract Audio. When the progress bar completes, preview the track in the player and click Download Audio.

Should I choose MP3, WAV, AAC or OGG?

MP3 is lossy and plays on virtually every device, which makes it the safe default. WAV is uncompressed and lossless, so it is the right choice if you will edit the audio further, but the files are large. AAC is lossy and gives better quality than MP3 at the same size, and is the native audio in most MP4 videos. OGG (Vorbis) is an open, royalty-free lossy format that is well supported on the web and on Linux.

Will extracting the audio lose quality?

Video soundtracks are already compressed, usually as AAC. Extracting to WAV keeps everything that is there. Extracting to MP3, AAC or OGG re-encodes lossy audio into another lossy format, which adds a small amount of loss; at normal bitrates it is not audible on typical playback equipment.

Is my video uploaded to a server?

No. FFmpeg compiled to WebAssembly runs inside your browser tab, so the video is read from your device, processed locally, and the audio file is written straight back to your downloads.

Does this remove the audio from my original video?

No. Your original file is untouched; the tool only produces a copy of the soundtrack. To create a silent version of the video, use the Remove Audio from Video tool.

Can I keep the original audio quality or extract only part of the video?

Yes. Choose Original track, no re-encoding to copy the soundtrack exactly as it is stored in the video: AAC audio from an MP4 or MOV becomes an .m4a file in seconds with no quality loss, and WebM audio stays WebM. To keep only a stretch, fill in From and To (for example 1:20 to 4:05) or press now while the player is at the right moment.

What video formats can I extract audio from?

Common containers work, including MP4, WEBM, MOV, AVI and MKV, as far as FFmpeg.wasm and your browser can decode them.

Can I extract only part of the audio?

Yes. To extract only a stretch, fill in From and To under 'Only part of the video' (for example, 1:20 to 4:05). To cut the extracted track into several pieces, use the Audio Splitter.

How long does extraction take?

Usually a few seconds to a minute. Extracting to WAV is fastest because the audio only has to be decoded; MP3 and OGG take slightly longer because they are re-encoded.

Is it legal to extract audio from a video?

Extracting audio from material you own or created yourself is fine. Copying a soundtrack from someone else's copyrighted video without permission generally is not. Check the rights before you redistribute anything.

How can I make an extracted audio file smaller?

Choose a compressed format such as MP3, AAC, or OGG rather than uncompressed WAV. For MP3 output, a lower bitrate creates a smaller file; for example, 128 kbps is smaller than 320 kbps, though it retains less audio detail. The Audio Extractor offers MP3 quality settings of 128, 192, and 320 kbps. If you plan to edit the audio, consider whether preserving an uncompressed or original track matters more than reducing file size.

Why is the extracted audio silent even though the video has sound?

Check whether the selected video contains an audio track and whether the preview is muted or its volume is turned down. Some files use audio codecs or stream arrangements that the browser processing engine may not handle as expected. Try another supported output format, such as WAV or MP3, and preview the result before downloading. If the original file itself plays silently in another player, the video may not contain usable audio.

Will converting a video soundtrack to WAV improve its sound quality?

Converting a lossy soundtrack to WAV does not restore audio detail that was discarded during earlier compression. WAV can preserve the decoded audio without adding another lossy compression step, which is useful for editing, but the source quality still sets the limit. If the original track option is available and suitable, it extracts without re-encoding. MP3, AAC, and OGG are compressed formats that can reduce file size.
