How to Extract Audio from a Video in Your Browser
Add your video file
Drag a video onto the upload area or click Choose Video File to pick one from your device. The file is read locally on your device, so even large clips stay on your computer.
Set the bitrate
Move the bitrate slider to balance quality against file size. Lower values such as 128 kbps suit speech and podcasts, while higher values up to 320 kbps preserve more detail for music.
Extract and download
Click Extract Audio. The browser decodes the video, renders the full audio track, and encodes it in real time. When it finishes, download the resulting MP3 file with the original name.
Bitrate Settings and What They Are Good For
The bitrate slider controls how much data per second is kept in the extracted audio. Higher bitrates sound better but produce larger files. Use this table to pick the right setting for your source material.
| Bitrate | Best for | Relative file size | Quality |
|---|---|---|---|
| 64 kbps | Voice memos, audiobooks, mono speech | Smallest | Basic, intelligible voice |
| 96 kbps | Spoken word, lectures, low-bandwidth sharing | Very small | Clear speech |
| 128 kbps | Podcasts, interviews, general use | Small | Good for talk content |
| 192 kbps | All-purpose default for mixed audio | Moderate | Very good |
| 256 kbps | Music with detail you want to keep | Larger | High |
| 320 kbps | Music extraction, archival copies | Largest | Highest available |
Is This the Right Tool for Your Job
You have the video file on hand
This tool works on video files already saved to your device, such as recordings, downloads, or exports. It does not fetch or download videos from streaming sites or links.
You want the complete soundtrack
The extractor captures the entire audio track from start to finish. If you only need a portion, extract first and then use a separate audio trimmer to cut the part you want.
Privacy matters for your footage
Because decoding and encoding happen in your browser, the video stays on your machine. This suits confidential meetings, personal recordings, or material you cannot upload.
Your browser can decode the format
Extraction relies on your browser built-in codecs. Common formats like MP4 and WebM work widely. If a file will not decode, convert it to MP4 first, then extract the audio.
Common Problems and Fixes
Could not decode audio from this video
Your browser may not support the codec inside the file. This is common with some MKV or AVI containers. Convert the video to MP4 with our video converter first, then run the extraction again.
Extraction is slow on a large file
The whole video is decoded in memory, so long or high-resolution files take longer and use more RAM. Use a desktop browser for big files and close other heavy tabs to free up memory.
The output file is silent
If the source video has no audio track, the result will be empty. Confirm the video actually plays sound, and check that the correct file was selected before extracting.
Drag and drop does nothing
The drop area only accepts files the browser recognizes as video. If your file is not detected, use the Choose Video File button instead, which lets you pick the file directly.
