VIDEO TO MP3

Extract audio from video online

Convert the full audio track or a selected section of an MP4, MOV, or AVI video to MP3. Processing happens locally in your browser.

How to turn a video into MP3

1. 1. Select the video file

   Open Trimflow and choose an MP4, MOV, or AVI file from your device.

2. 2. Choose the audio section

   Set the start and end points on the timeline. Leave the full duration selected if you need the complete soundtrack.

3. 3. Extract the MP3

   Select Extract MP3. Trimflow removes the video stream and encodes the selected audio locally as an MP3 file.

4. 4. Download the audio

   Preview the result and save the MP3 directly to your device.

Private, browser-based extraction
