You can test how to remove webcam background right now in your browser.

Just visit the Web AR SDK page and test it out.

It is our background subtraction library.

It uses a convolutional neural network and machine learning algorithms trained to segment the humans from the background in videos captured by a web camera.

Simply put, you can integrate it with your web app and let users remove, change, and animate backgrounds.



Real-time background subtraction using web camera

Users don't need to download an app to use video background removal.

Just build a cross-platform real time background removal experience that supports any browser.

Does My Business Need a Video Background Removal?

Yes! This feature is a must-have in 2024 if your app is designed for:

Video communication

Video background removal perfectly fits video conferencing apps and can be integrated together with video calling SDK providers such as Agora.

Virtual backgrounds embedded in video chat apps enhance the communication experience. Combined with face filters and beautification, they make users engaged and confident as well.

Broadcasting & streaming

Users can change backgrounds while broadcasting from their web camera.

With the background remover feature, you help users produce professional and high-quality live stream videos.


Video background removal software helps you make the educational process more immersive.

It can recreate a classroom environment to eliminate distractions or help teachers present material more effectively.

Background Removal Video with Face Filters 

We don't just stop on real time background removal, but expand to be compatible with our Face AR.

It includes multiple features like facial effects, filters, virtual try on, and beautification.

How does it work?

Our Web AR face-tracking technology recognizes the human face's presence in real-time. With this, users can add realistic or fun webcam face filters to enrich their video communication.

This way, you can meet any demands of users.

First, you increase privacy.

Users can hide their real backgrounds and ensure nobody knows where they actually are. This also brings high comfort users no longer need to put in additional effort and clean their rooms if there is a mess up.

Second, you make them feel more confident.

Real-time beautification, effects, and filters allow users to tune their appearance.

You can also add face touch up filters to virtual backgrounds and improve the user experience even more.



Background removal and face beautification

For video processing and effect rendering, we use OpenGL shaders.

They render 3D graphics realistically without glitches.

What's more, we keep the solution lightweight for fast inference and small download size.

It becomes possible by optimizing the pack of AR filters for the web.

How to Remove Webcam Background: 4 Steps

3. Download Face Effects

The camera background removal feature comes as part of the effect along with beautification and AR makeup solutions. Just download the exact features you need and start using them.

4. Call the Background Subtraction with an API

The final step is to activate the webcam background removal functionality. You need to call this feature using the API methods described in our instructions in greater detail.

Technical Features of Banuba Web AR

To deliver real-time background subtraction on the web, we optimized machine learning algorithms for low power consumption and extensive device coverage.

Real-time performance

Apart from Chrome and Firefox, it supports Safari and WebGL 1.0 starting from SDK v1.0 allowing for a cross-platform virtual background experience. It can be integrated in any web AR application or platform.

  • Firefox: 22-30 FPS (camera), 40-45 FPS (background model)
  • Chrome: 30 FPS (camera), 50-60 FPS (background model)
  • Safari: Webcam 20 FPS (camera), 40 FPS (background model)


The webcam background remover is supplied with SIMD (single instruction multiple data) that processes multiple data with a single instruction which dramatically improves performance.

If the browser supports SIMD, it'll be used automatically to enhance performance.

A regular, lighter version of the background subtraction library is used if the browser goes without SIMD support.

If you want face filters or beautification applied together with backgrounds in your app, you'll need face tracking, which implies additional weight.

  • Background Subtraction: 8.4 mb (SIMD), 7.3 mb (regular)
  • Background Subtraction + Face Tracking Neural Network: 12.8 mb (SIMD), 11.6 mb (regular)


It supports up to 1,8 m which fits most of the video communication scenarios.
