Detach Audio from Video — Extract Audio Online Free
Separate the audio track from any video segment with one click. iviCut lets you extract audio from video in your browser — no uploads, no server processing, and no software to install.
Why Detach Audio?
- Create podcasts or voiceovers from existing video content
- Export dialogue or music as a standalone MP3 file
- Edit audio independently — adjust volume, trim, add fades — without affecting the video
- Mute the original video and replace with new music or narration
- Repurpose content across platforms: turn a YouTube video into an audio clip for social media
How to Detach Audio
- Open the editor and add a video to the timeline
- Click on the video segment to open Video Settings
- Find the Detach Audio button (below the Volume slider)
- Confirm the action in the dialog
- Done — the audio is extracted, the video is automatically muted, and a new Audio Overlay appears on your timeline
The entire process runs locally in your browser using FFmpeg.wasm. Your files never leave your device.
What Happens After Detaching
| Original Video Segment | New Audio Overlay |
|---|---|
| Automatically muted (volume → 0%) | Placed on the timeline at the same position |
| Marked as "Audio Detached" | Linked back to the source video |
| Can be unmuted manually anytime | Fully editable: trim, fade, volume |
Export Detached Audio as MP3
After detaching, open the Audio Overlay settings and click Export as MP3 to download the extracted audio. The file is a high-quality MP3 encoded with the best available bitrate — ready for use in podcasts, social media, or other projects.
This also works for recorded voiceovers — any audio you record in iviCut can be exported as MP3.

Privacy & Performance
All audio extraction happens 100% client-side using FFmpeg.wasm. No files are uploaded to any server. Processing speed depends on your device, but most clips are extracted in seconds.
