SweetcraftExtract MP3 from video
Save the first audio track of a video as an MP3 file.
About this tool
Sometimes only the sound of a video matters: a lecture recording, an interview, a voice memo captured on camera, or the audio track of a webinar. This tool extracts the first audio stream from your video file and saves it as an MP3 that plays anywhere, using FFmpeg locally in your browser.
Because MP3 is a lossy format, the result cannot sound better than the audio inside the original video, and re-encoding an already compressed source can reduce quality slightly. A video with no audio track cannot be converted, and additional tracks, subtitles and cover artwork are not included in the output.
How to use Extract MP3 from video
- Choose up to four video files that contain an audio track (up to 150 MiB each, 250 MiB per batch).
- No format choices are needed — the first audio stream is extracted and encoded as MP3.
- Run the extraction, play the preview to confirm it is the track you expected, and download each MP3.
Keep the original files and inspect the exported result before publishing or sharing it.
Frequently asked questions
Which audio track is exported?
The first audio stream is used. A video without audio cannot produce an MP3. Other tracks, subtitles and attached artwork are omitted.
Does MP3 conversion improve audio?
No. MP3 is lossy; re-encoding compressed sources can reduce quality. Higher bitrate increases size and cannot restore missing detail.
Are my files uploaded?
No. FFmpeg runs on your device. The engine assets download on first use; your selected media stays in browser memory. Each file is limited to 150 MiB and each batch to 250 MiB.
