How to Extract Audio from Video
Upload your video file using the form above. Our converter uses FFmpeg to extract the audio track and encode it as a high-quality MP3 file. The process preserves the original audio quality while discarding the video stream, resulting in a much smaller file size.
We support all major video formats including MP4, AVI, MKV, MOV, WMV, FLV, and WEBM. The extracted MP3 uses variable bitrate encoding (VBR) at approximately 190 kbps, providing excellent quality suitable for music and speech.
Why Extract Audio from Video Files
Extracting audio from video is useful when you want to listen to content without watching. Convert video podcasts, lectures, interviews, or music videos to MP3 for offline listening on any audio player or smartphone.
MP3 files are significantly smaller than video files, making them ideal for portable devices with limited storage. A 500 MB video might produce a 50 MB MP3 file with identical audio content.
Common Use Cases for Video to MP3
Podcast and lecture conversion: Extract audio from video podcasts, online courses, or recorded lectures to listen during commutes, workouts, or while multitasking.
Music video audio: Save the audio track from music videos for your personal music library. Perfect for songs that are only available as video content.
Audio backup: Create audio-only backups of important video recordings such as interviews, meetings, or family events. Audio files are smaller and easier to archive.

| Audio backup: Create audio-only backups of important video recordings such as interviews, meetings, or family events. Audio files are smaller and easier to archive. | Start with the highest quality video source available. Audio quality in the extracted MP3 cannot exceed the quality of the original audio track.

Check that the video actually contains an audio track — some silent videos or GIFs converted to video format have no audio to extract. |
| The extracted MP3 quality depends entirely on the source video's audio track. Video files typically contain audio encoded at 128-320 kbps using AAC, MP3, or other codecs. Our converter extracts and re-encodes this audio preserving quality up to approximately 190 kbps VBR. Re-encoding from already-compressed audio introduces minimal additional quality loss when using high-quality settings. | For maximum quality preservation, consider extracting to lossless formats like WAV or FLAC when the source video contains high-bitrate audio. However, for most listening purposes—podcasts, spoken content, casual music—our MP3 output provides excellent quality at a fraction of the file size. | When you need to extract audio from multiple videos, our converter processes files individually. For batch processing of many videos, consider desktop tools like FFmpeg which can automate extraction across entire folders.

Best Practices for Audio Extraction
Start with the highest quality video source available. Audio quality in the extracted MP3 cannot exceed the quality of the original audio track. Videos with poor audio will produce poor MP3 files.
For music, use videos with stereo audio rather than mono when possible. Check that the video actually contains an audio track — some silent videos or GIFs converted to video format have no audio to extract.
When to Extract Audio vs Keep Video
| MP3 files are significantly smaller than video files, making them ideal for portable devices with limited storage. A 500 MB video might produce a 50 MB MP3 file with identical audio content. | <strong>Podcast and lecture conversion:</strong> Extract audio from video podcasts, online courses, or recorded lectures to listen during commutes, workouts, or while multitasking. | <strong>Music video audio:</strong> Save the audio track from music videos for your personal music library. Perfect for songs that are only available as video content. |
|---|---|---|
| Podcasts/interviews | Best choice — audio is primary content | Only if visual context matters |
| Music videos | For audio-only listening | For full experience |
| Lectures/courses | For audio review while commuting | If slides/demos are important |
| Storage concerns | 90-95% smaller files | Large file sizes |
| Mobile playback | Works on all audio players | Requires video player |
Audio Quality Considerations
The extracted MP3 quality depends entirely on the source video's audio track. Video files typically contain audio encoded at 128-320 kbps using AAC, MP3, or other codecs. Our converter extracts and re-encodes this audio preserving quality up to approximately 190 kbps VBR. Re-encoding from already-compressed audio introduces minimal additional quality loss when using high-quality settings.
For maximum quality preservation, consider extracting to lossless formats like WAV or FLAC when the source video contains high-bitrate audio. However, for most listening purposes—podcasts, spoken content, casual music—our MP3 output provides excellent quality at a fraction of the file size.
Processing Multiple Videos
When you need to extract audio from multiple videos, our converter processes files individually. For batch processing of many videos, consider desktop tools like FFmpeg which can automate extraction across entire folders. Our online tool works best for occasional conversions or when you don't want to install software.
Videos from different sources may have varying audio quality levels. Professional productions typically include high-quality audio tracks, while user-generated content varies widely. Check the resulting MP3 quality before processing many similar videos to ensure the source quality meets your needs.
