You recorded a webinar and just need the audio. Or you want the soundtrack from a home video. Maybe you’re pulling dialogue from a clip for a podcast edit. Whatever the reason, extracting audio from video is one of those tasks that sounds like it should be simple – and honestly, it is, once you know which tool to grab.
I tested 8 different tools over the past two weeks, running the same 47-minute 1080p MP4 file through each one. Some were fast. Some were painfully slow. One online tool corrupted the output on files over 200 MB. Here’s what actually worked.
If your goal is specifically converting MP4 files to MP3, I covered that in detail in my MP4 to MP3 conversion guide. This article covers broader extraction – any video format to any audio format, with more control over quality settings.

1. VLC Media Player – The Tool You Already Have
Most people don’t realize VLC can extract audio. It’s buried under Media > Convert/Save, which isn’t exactly intuitive naming. But once you find it, the process takes about 30 seconds to set up.
How to extract audio with VLC
Open VLC and go to Media > Convert/Save (or press Ctrl+R). Click Add and select your video file. Hit Convert/Save at the bottom. In the Profile dropdown, pick “Audio – MP3” or “Audio – FLAC” depending on what you need. Choose your destination file and click Start.
For my 47-minute test file (1.2 GB MP4), VLC finished the MP3 extraction in about 90 seconds. The output was a clean 44 MB MP3 at 128 kbps. Bumping it to 320 kbps gave me a 109 MB file with noticeably better quality on headphones.
Pros:
- Already installed on millions of computers
- No file size restrictions
- Supports most video formats as input (MKV, AVI, MOV, WebM, MP4)
- No watermarks or ads
Cons:
- The Convert/Save menu is confusing the first time
- Can’t do batch processing without workarounds
- Limited bitrate control compared to FFmpeg
2. FFmpeg – Maximum Control, Zero GUI
If you’re comfortable with the command line, FFmpeg is the answer. Period. Every other tool on this list either uses FFmpeg under the hood or wishes it did.
Basic extraction command
The fastest way to extract audio without re-encoding:
ffmpeg -i input.mp4 -vn -acodec copy output.aacThe -vn flag strips the video. The -acodec copy part copies the audio stream directly – no quality loss, no re-encoding, finishes in seconds regardless of file length. My 47-minute test file extracted in 3 seconds flat.
Want MP3 instead? You’ll need to re-encode:
ffmpeg -i input.mp4 -vn -ab 320k -ar 44100 output.mp3Need to process an entire folder of videos? One line:
for f in *.mp4; do ffmpeg -i "$f" -vn -acodec copy "${f%.mp4}.aac"; donePros:
- Fastest extraction tool tested (3 seconds for stream copy)
- Handles every format ever invented
- Batch processing is trivial
- Extract specific time ranges with -ss and -t flags
- Completely free, open source
Cons:
- No graphical interface
- Command syntax takes practice to learn
- Error messages aren’t beginner-friendly
3. Audacity – When You Need to Edit the Audio Too
Audacity can import video files directly (it uses FFmpeg libraries behind the scenes). The real advantage here is that your audio lands right in the editor – trim silence, remove noise, normalize volume, then export. One tool handles everything.
Steps to extract
Go to File > Import > Audio and select your video file. Audacity will extract the audio track and display the waveform. Edit if needed. Then File > Export Audio and pick your format.
The import took about 40 seconds for my test file – slower than VLC or FFmpeg because Audacity loads the entire waveform into memory. On a machine with 8 GB RAM, files over 2 hours might cause sluggish performance. Worth it if you’re planning to edit anyway.
I use Audacity specifically when I’m pulling interview audio from video recordings. The noise reduction filter handles background hum from air conditioning, and the compressor evens out volume differences between speakers. If you’re looking for more audio editing options, check out my roundup of free audio editing software.
Pros:
- Full audio editor – not just extraction
- Noise reduction, normalization, effects built in
- Cross-platform (Windows, Mac, Linux)
- Open source, completely free
Cons:
- Slower import than dedicated converters
- Needs FFmpeg libraries installed separately for some formats
- Overkill if you just want a quick MP3
4. 123apps Audio Converter – Best Online Option
Of all the online tools I tested, 123apps handled the job with the least friction. No account required. No watermarks. Upload, pick your format, download. Done.
The free tier allows files up to 2 GB, which covered my 1.2 GB test file without issues. Upload took about 2 minutes on a 100 Mbps connection, and the conversion finished in another 30 seconds server-side. Total time: under 3 minutes from start to download.
One feature I appreciate: you can adjust quality settings before converting. The MP3 slider goes from 64 kbps (economy, tiny file) to 320 kbps (maximum quality). Most online tools just give you a default with no control.
Pros:
- 2 GB file size limit – generous for a free tool
- No registration needed
- Quality/bitrate controls available
- Clean interface, no dark patterns
Cons:
- Upload time depends on your internet speed
- No batch processing
- Ads on the page (not intrusive, but they’re there)
5. Kapwing – Quick and Visual
Kapwing is primarily a video editor, but its export options include audio-only formats. The approach is different from other tools – you import the video into Kapwing’s timeline editor, and then export as MP3.
The free plan limits uploads to 250 MB and exports at 720p for video (though audio quality isn’t affected by video resolution limits). There’s a watermark on video exports, but audio exports come clean.
Honestly, Kapwing is overkill for pure audio extraction. Where it earns its spot is when you want to trim the video first – cut out the intro, remove dead air at the end – and then export just the audio from what’s left. The visual timeline makes that easy compared to typing FFmpeg timestamp commands.
Pros:
- Visual timeline for trimming before extraction
- No watermark on audio exports
- Works in any modern browser
Cons:
- 250 MB limit on free plan
- Requires account creation
- Only exports to MP3 (no WAV/FLAC option on free tier)
- Slower than dedicated converters
6. Clideo – Simplest Drag-and-Drop
Clideo’s audio extraction tool strips the interface down to the minimum. Drag your video onto the page, pick your output format (MP3, M4A, WAV, or FLAC), and hit convert. That’s it.
The 500 MB free limit is the main constraint. My 1.2 GB test file was rejected, so I tested with a shorter 380 MB clip. Processing was fast – about 45 seconds after upload. The output quality matched the original audio track without noticeable degradation.
Free exports include a small Clideo watermark on video, but audio files come without any watermark. Files are deleted from their servers after 24 hours according to their privacy policy.
Pros:
- Extremely simple interface
- Multiple output formats including FLAC
- No account needed for basic use
- Google Drive and Dropbox import supported
Cons:
- 500 MB file size cap
- Slower processing than desktop tools
- Limited to 2 free operations per day
7. FreeConvert – Batch Online Processing
FreeConvert stands out from other online tools because it handles up to 5 files simultaneously on the free plan. If you have a folder of meeting recordings and need audio from each one, this saves real time compared to processing them one by one.
The 1 GB file size limit per file is reasonable. Upload all your files, select MP3 (or WAV, AAC, FLAC, OGG), adjust settings if needed, and hit Convert. Each file processes independently – you can download finished ones while others are still converting.
Quality settings are detailed: codec, sample rate, bitrate, channels, volume adjustment. You can even trim the audio by setting start and end times before conversion. Not bad for a browser tool.
Pros:
- Batch processing (up to 5 files free)
- 1 GB per file limit
- Advanced settings: trim, volume, sample rate
- Wide format support
Cons:
- Daily conversion limit (25 minutes total on free plan)
- Slower upload/processing for larger files
- Some advanced options locked behind paid plan
8. HandBrake – Desktop Batch Processing
HandBrake is known as a video transcoder, but it handles audio extraction well enough if you set the right options. The queue system lets you add dozens of files and process them overnight.
The setup isn’t obvious. You need to: open your video in HandBrake, go to the Audio tab, set your preferred codec (AAC, MP3, or FLAC), then under the Output Settings, you can choose a container that supports audio-only output. It’s not as clean as FFmpeg for this task, but the preset system means you only configure it once.
Processing speed was solid – about 70 seconds for my test file, which puts it between VLC and FFmpeg. The batch queue is where HandBrake pulls ahead of VLC: add 50 files, hit Start, walk away.
Pros:
- Batch queue for processing many files
- Saveable presets for consistent output
- Cross-platform (Windows, Mac, Linux)
- Free and open source
Cons:
- Interface designed for video transcoding, not audio extraction
- Audio-only output requires workaround settings
- Fewer audio format options than FFmpeg
Which Tool Should You Actually Use?
Here’s my honest take after testing all eight:
For a single file, right now: Use VLC. You probably have it installed already, and the conversion takes 90 seconds. No downloads, no signups, no uploading to someone else’s server.
For batch processing: FFmpeg if you’re comfortable with the terminal. HandBrake if you want a GUI. The time difference adds up fast when you’re processing 20+ files.
For editing the audio after extraction: Audacity. Import the video, trim the parts you don’t need, clean up noise, export. One workflow instead of two separate tools.
For quick online extraction (no install): 123apps Audio Converter has the best combination of file size limit (2 GB), format options, and quality controls among the online tools I tested.

Tips for Better Audio Extraction
Choosing the right format
MP3 at 192-320 kbps handles 90% of use cases. Podcasts, music rips, voice recordings – MP3 plays everywhere and the file sizes are manageable. Go with 320 kbps if quality matters to you, 192 kbps if storage space is tight.
WAV or FLAC if you plan to edit the audio further in a DAW or professional editor. These are lossless – no quality degradation from re-encoding. The files are 5-10x larger than MP3, but you keep the original fidelity.
AAC at 256 kbps gives you slightly better quality than MP3 at the same bitrate, with smaller files. Apple devices and most modern players support it. Just be aware that some older hardware media players might not.
Extracting audio from specific timestamps
Don’t want the full audio track? FFmpeg handles time ranges cleanly:
ffmpeg -i input.mp4 -vn -ss 00:05:30 -t 00:10:00 -ab 256k output.mp3This grabs audio starting at 5 minutes 30 seconds, for a duration of 10 minutes. Way faster than extracting the whole file and trimming afterward, especially on long recordings.
Dealing with multi-track audio
Some video files (especially MKV containers) have multiple audio tracks – maybe English and Spanish, or a commentary track. FFmpeg lets you pick which one:
ffmpeg -i input.mkv -vn -map 0:a:1 -acodec copy output.aacThe 0:a:1 selects the second audio track (zero-indexed). Use ffprobe input.mkv to see what tracks are available before extracting.
FAQ
Can I extract audio from a video for free?
Yes. VLC Media Player, Audacity, FFmpeg, and several online tools like 123apps Audio Converter let you extract audio from any video file at no cost. Desktop tools have no file size limits, while most online tools cap uploads at 500 MB to 2 GB on free plans.
What is the best format to extract audio from video?
MP3 (128-320 kbps) works for most situations – podcasts, music rips, voice memos. If you need lossless quality for professional editing, go with WAV or FLAC. AAC is a good middle ground if you want smaller files without losing too much quality.
How do I extract audio from a YouTube video?
First download the YouTube video using a tool like yt-dlp or 4K Video Downloader. Then use any of the extraction tools in this guide – VLC, FFmpeg, or an online converter – to pull the audio track. Some tools like yt-dlp can download audio-only directly with the -x flag.
Does extracting audio from video reduce quality?
It depends on your output format. If you extract to a lossless format (WAV, FLAC), quality stays identical to the original audio track. Converting to MP3 or AAC involves re-encoding, which technically loses some data, but at 256-320 kbps most people can’t hear the difference.
Is there a way to extract audio from video without installing software?
Yes. Online tools like 123apps Audio Converter, Kapwing, Clideo, and FreeConvert all work directly in your browser. Upload your video, pick an output format, and download the audio file. The main trade-off is file size limits – most free tiers cap at 500 MB to 2 GB.
