Follow these three simple steps to extract MP3 audio from a video. No software installation required. Free and secure.
Select a Video
Choose an MP4, MOV, WebM, AVI, MKV, M4V, MPEG, MPG, FLV, WMV, 3GP, or OGV video containing the audio you want to save.
Choose the MP3 Audio Settings
Keep the automatic sample rate and channel layout or choose 22.05, 44.1, or 48 kHz and mono or stereo output.
Extract and Download
Start audio extraction, review the original video and MP3 file sizes, and download the completed MP3 file.
How Does the Video to MP3 Converter Work?
The CompressFly video to MP3 converter reads the first audio stream in your selected video, leaves out the picture, and re-encodes the extracted sound as a 192 kbps MP3. You can keep the automatic sample rate and channel layout or select the available audio settings before extraction.
Audio extraction runs directly in your browser. Your video is not uploaded to a server, and the completed MP3 file downloads from the browser to your device.
What "directly in your browser" means
- Your video is not uploaded to a server.
- Audio extraction and MP3 encoding run locally on your device.
- The completed MP3 file downloads directly from your browser.
When to Convert Video to MP3
Extract MP3 audio when you need a compact listening, transcription, or sharing file without the video's picture.

Save speech, music, or other recorded sound when you want to listen without loading or keeping the picture.
Prepare Audio for Transcription
Create a familiar MP3 input for transcription, captioning, note-taking, or speech-review software.
