How to Add a Voiceover to a Video for Free
Record narration over a video right in your browser — watch the footage as you speak, then export. Free, no watermark, nothing uploaded.
Screen recordings and demos are far more useful with narration. But most voiceover tools want you to upload your video, sign up, or accept a watermark. You can skip all of that and record a voiceover in your browser — while watching the video play, so your words stay in sync.
Record a voiceover in 5 steps
- Open the Video Editor and upload your video (even a silent screen recording works).
- Open the "Add music / voiceover" section and choose "Record a voiceover".
- Press record — a 3-2-1 countdown gives you a moment, then the video plays as you narrate. A live mic meter shows it's picking up your voice.
- Choose "Replace original audio" (for a silent clip) or "Mix" to keep the existing sound, and set the volume.
- Export the video and download it — one file, ready to share.
The video and your microphone are processed entirely on your device with an in-browser video engine. Nothing is uploaded, and there's no watermark.
Try the Video EditorResize, trim, speed up, filter, caption, denoise and add music to a video — upload once, apply everything, export once.Getting clean narration
- Watch the live mic meter — if it stays flat, your microphone isn't being picked up (check your system input device).
- Use headphones if your video already has sound, to avoid echo.
- Record in a quiet room; you can also apply noise reduction in the same editor.
- The video stops recording automatically when it ends, so you don't clip the last word.
The same editor also lets you trim, resize for Reels/Shorts, add captions and mix in music — all in one export, all in your browser.
