संक्षेप में (BLUF): Replace your video background with a virtual backdrop for free, running entirely on your device: the original file is never uploaded to any server, zero tokens are charged, and there is no paid API. Blur your background just like in Zoom and Google Meet, pick a ready-made virtual interior (modern office, photo studio, cozy room, nature bokeh), or upload your own image or video. AI person segmentation runs directly in your browser via WebGPU and WebAssembly, ensuring total privacy and immediate download in MP4 or WebM format.
The tool combines neural person segmentation with hardware-accelerated client-side rendering (sb2702/longpipe). The MediaPipe Selfie Segmenter model analyzes incoming video frames frame-by-frame, calculating an accurate alpha mask with feathered soft edges to preserve hair strands and clothing contours before compositing onto your chosen backdrop.
Everything runs on modern open web standards: video decoding and muxing are handled via WebCodecs, while background compositing, color transformations, and blur shaders are computed directly on your graphics hardware via WebGL and Canvas. This provides exceptional throughput with zero network overhead.
Background blur (Bokeh effect) hides cluttered rooms or private surroundings while keeping full focus on the speaker. Three intensity presets are available: subtle light blur (10 px) for natural depth of field, medium blur (20 px), and strong background separation (35 px).
Preset virtual backdrops include a modern corporate office with soft ambient window lighting, a professional photo studio with subtle radial illumination, a cozy warm living room, an outdoor nature scene with lush green bokeh, and an abstract tech gradient. You can also upload any custom image or video loop, or choose a solid color for chroma keying.
The primary advantage of a browser-based tool is absolute data privacy. Your video clips, faces, voices, and confidential materials are never transmitted to our servers or processed by third-party cloud APIs. The entire pipeline executes locally inside your browser memory and GPU buffers.
No registration or sign-in is required to use the tool, no account tokens or credits are consumed, and there are no usage limits or hidden subscription paywalls. You get a completely free, fast, and secure tool for polished video presentations.
For best segmentation results, ensure balanced lighting across your face and shoulders without harsh backlighting or heavy shadows. Wearing clothing that contrasts clearly with the original background also helps achieve clean, sharp contours.
Keep your camera steady on a tripod or desk mount: a stable frame helps the neural network track contours smoothly between consecutive frames, maintaining a natural and professional look throughout the clip.
The tool uses MediaPipe Selfie Segmenter combined with an efficient WebGPU and canvas pipeline inspired by sb2702/longpipe, running client-side.
