Extracting audio from a video file is a common need — whether you want to save a podcast that was recorded as video, pull the soundtrack from a music video, or grab dialogue from a lecture recording. This guide shows you the easiest ways to do it.
Why Extract Audio from Video?
There are many practical reasons to separate the audio track from a video file:
Podcast creation — Extract audio from a video recording for podcast distribution. Record on video (for YouTube), then extract audio for your podcast feed. See our dedicated podcast audio extraction guide.
Music — Save the audio from music videos for offline listening.
Lectures and talks — Convert recorded presentations to audio-only files for on-the-go listening.
Storage — Audio files are dramatically smaller than video files. A 500 MB video might produce a 30 MB MP3.
Editing — Isolate audio tracks for use in other projects like presentations, remixes, or sound design.
Method 1: Online Converter (Fastest)
The quickest approach is using FileConvertTool's video to audio converter:
1. Go to the converter — choose your specific conversion:
- MP4 to MP3 (most popular)
- MOV to MP3 (iPhone videos)
2. Upload your video file (MP4, MOV, MKV, AVI, WebM, FLV, or WMV — up to 200 MB).
3. Select your desired audio format:
- MP3 — Universal, small files
- WAV — Lossless, for editing
- AAC — Efficient, Apple-friendly
- OGG — Open-source, for games
4. Click Convert and download your audio file.
The entire process takes seconds for most files and works on any device without installing software.
Choosing the Right Audio Format
MP3
The universal choice. MP3 works everywhere and offers good quality at small file sizes. Use 320 kbps for high quality or 128 kbps for smaller files.
Best for: General listening, sharing, podcast distribution.
Convert: MP4 to MP3 · MOV to MP3 · MKV to MP3
WAV
Uncompressed, lossless audio. WAV files are much larger but preserve the full quality of the original audio track.
Best for: Audio editing, professional production, archival.
Convert: MP4 to WAV · MOV to WAV · MKV to WAV
FLAC
Lossless compression — same quality as WAV but roughly half the file size.
Best for: Audiophile listening, music archival, when storage space matters.
AAC
More efficient than MP3 at the same bitrate. AAC is the default for Apple devices and YouTube.
Best for: Apple ecosystem, modern streaming workflows.
Convert: MP4 to AAC · MOV to AAC
OGG
Open-source alternative to MP3 with slightly better quality at equivalent bitrates.
Best for: Gaming, open-source projects, web applications.

Quality Tips
The audio quality of your extracted file can never exceed the quality of the source video's audio track.
Most video files use AAC or AC3 audio at 128-256 kbps — extracting to 320 kbps MP3 will not improve quality beyond the source.
For maximum quality preservation, extract to WAV or FLAC (lossless formats).
If you plan to edit the audio afterwards, always extract to WAV first, edit, then export to your final format.

FileConvertTool converts files you upload — if you have a downloaded video file (MP4, WebM), you can extract the audio to MP3 instantly. We do not support direct URL downloads from streaming platforms.
What is the best audio format to extract from video?
For sharing and general listening, MP3 at 256-320 kbps is ideal. For editing or professional use, extract to WAV for lossless quality. For archival, use FLAC. See our audio format comparison for a detailed breakdown.
Does extracting audio reduce quality?
Not if you extract to a lossless format (WAV or FLAC). When extracting to MP3, there is some compression, but at 256+ kbps the quality loss is minimal. The extracted audio can never exceed the quality of the original video's audio track.
