How to Blur a Video Background Online

The easiest and fastest way to create a video background blur online is with BlurMe, a 100% browser-based editor that uses AI to detect people and backgrounds instantly. Just upload your clip and apply the auto blur background in seconds.

Step-by-Step: Blur a Video Background with BlurMe

1. Go to BlurMe Studio online.
   Visit BlurMe in your browser. It works on any device, Windows, macOS, Android, or iPhone.

2. Upload Your Video
   Drag and drop your clip or select it from your computer. BlurMe supports all major formats (MP4, MOV, AVI).

3. Select Full-Screen Blur to Blur the Video
   This ensures the entire video including the background starts blurred. You’ll then decide what should remain visible.

4. Enable AI Detection
   Toggle Enable AI to let BlurMe automatically detect faces, bodies, cars, and license plates. Now, simply click or select what you want to keep visible (like your face or main subject). BlurMe will instantly unblur those selected areas, keeping everything else in the background blurred.

5. Adjust Blur Strength
   Use the slider to customize how strong or subtle your blurred background appears. You can even switch between full-screen blur and partial blur options.

6. Export Your Blurred Video
   Once satisfied, click Export. Your video will download with a professional background blur effect — no watermark if you sign up for free.

That’s it. No need for editing expertise. BlurMe’s auto blur background handles it for you.

How to Blur Parts of a Video (Manual Selection)

• Select the Custom Blur option in BlurMe.
• Draw over the area you want to blur.
• Adjust the blur level or size as you want.
• Export your edited video instantly.

How to Blur Video Background in CapCut

If you prefer editing inside an app, here’s how to blur background of a video in CapCut:

1. Open your video in CapCut.
2. Tap on Effects → Video Effects → Basic.
3. Select the Blur effect.

How to Blur Background of a Video on Canva

Canva also offers a basic video blur effect for simple projects:

Tips for Creating a Professional Blurred Background Effect
