Video Background Remover

Remove or replace video backgrounds with AI — entirely in your browser. No uploads, no watermarks, 100% free.

MP4, MOV, or WebM • Max 200MB

Pro Tips

  • 1.Good lighting matters. The AI works best when there is clear contrast between the subject and background. Avoid backlighting.
  • 2.Keep videos short. Processing happens frame-by-frame. A 30-second 720p video (~900 frames) is ideal. Longer videos work but take more time and memory.
  • 3.Tune edge settings. If you see halos or rough edges, lower Edge Sensitivity and increase Edge Smoothing. For sharp cutouts, do the opposite.
  • 4.Use Chrome or Edge. These browsers have the best WebGL and MediaRecorder support, producing faster processing and higher quality output.
  • 5.Green screen output. Choose Solid Color with the green preset to create footage ready for chroma key compositing in any video editor.

What Is the Video Background Remover?

The Video Background Remover is a free browser-based tool that uses AI to separate people from their backgrounds in any video. It runs entirely on your device using MediaPipe's machine learning model — a production-grade segmentation network developed by Google that identifies human silhouettes with pixel-level accuracy at real-time speeds.

Unlike server-based tools that require uploading your footage (and trusting a third party with your content), this tool processes every frame locally. Your video never leaves your browser. You can replace the background with a solid color, a blurred version of the original, a custom image, or remove it entirely for a transparent output. The result downloads as a WebM file with no watermarks, no signups, and no usage limits.

How to Remove a Video Background

Step 1: Upload your video. Drag and drop or click to browse. The tool accepts MP4, MOV, and WebM files up to 200MB. Shorter clips (under 60 seconds) process fastest and produce the best results.

Step 2: Choose your background. Pick from four options: a solid color (white, green screen, blue, black, or any custom color), a blurred version of the original background, a custom image you upload, or fully transparent. Each option has its own use case — solid green for compositing in video editors, blur for a professional webcam look, and transparent for layering in motion graphics.

Step 3: Adjust edge settings. The Edge Sensitivity slider controls how aggressively the AI distinguishes person from background. Higher values create tighter masks (less background bleed), while lower values include more boundary pixels (better for loose hair or accessories). Edge Smoothing adds a subtle gaussian blur to mask edges, eliminating jagged outlines.

Step 4: Process and download. Click the process button and watch the live preview as each frame is segmented. When complete, preview the result side-by-side with the original and download your background-free video as a WebM file.

Key Features and Technical Details

AI-Powered Segmentation: The tool uses MediaPipe's Image Segmenter, a lightweight neural network optimized for real-time inference in browsers via WebGL. The model is approximately 5MB and downloads once on first use, then caches in your browser for instant loading on return visits.

Audio Preservation: Unlike many background removal tools that strip audio, this tool extracts the original audio track and mixes it into the output video. Toggle audio off if you only need the visual content.

Quality Control: Choose between Low, Medium, and High output quality settings that control the video bitrate. Higher quality produces larger files but preserves more detail in the segmented output. For most use cases, Medium quality provides the best balance of file size and visual fidelity.

Graceful Fallback: If your browser does not support WebGL or the AI model fails to load, the tool automatically falls back to a basic chroma-key mode. While less accurate than AI segmentation, this ensures the tool remains functional across a wider range of devices and browsers.

Frequently Asked Questions

Does this tool upload my video to a server?
No. All processing happens entirely in your browser using on-device AI. Your video never leaves your computer, is never stored on any server, and is never seen by anyone else. You can verify this by disconnecting from the internet after the AI model loads — the tool continues to work offline.
How long does processing take?
Processing speed depends on your video length, resolution, and device performance. A 10-second 720p clip typically takes 30-60 seconds on a modern laptop. 1080p videos take longer since each frame has 2.25x more pixels to segment. For best performance, use Chrome or Edge on a device with a dedicated GPU, and keep your video under 60 seconds.
Can I use this as a green screen replacement?
Yes. Select 'Solid Color' as the background option and choose the green preset (#00B140) to create a virtual green screen from any video. This is useful for importing footage into video editors like Premiere Pro, DaVinci Resolve, or Final Cut Pro that support chroma key compositing. You can also use any custom solid color.
Why is the output in WebM format instead of MP4?
The tool outputs WebM because browser-native video encoding (via the MediaRecorder API) supports WebM with VP8/VP9 codecs. MP4 encoding requires additional libraries that would increase load times significantly. WebM plays in all modern browsers, Discord, Slack, and most video editors. If you need MP4, use our free Video Converter tool to convert the output.
The edges around people look rough. How can I improve them?
Adjust two settings: increase Edge Smoothing (adds a soft blur to mask edges, reducing jagged outlines) and lower Edge Sensitivity (includes more of the boundary pixels around the person). The defaults work well for most videos, but scenes with loose hair, thin accessories, or fast motion benefit from tuning. Good lighting with contrast between the subject and background also improves AI accuracy.
