Webcam Background Removal Software: 2026 Guide

TL;DR:

• Webcam background removal replaces or blurs whatever is behind a person in a live camera feed, and modern implementations do it with a neural network instead of a green screen.

• Banuba's Background Remover API performs the segmentation on the end user's device, so camera frames are never uploaded, which is what makes it usable in GDPR-sensitive products.

• On the web, Banuba Web AR SDK runs in Chrome, Firefox, and Safari on both desktop and mobile, and requires WebGL 2.0 or higher.

• Banuba's published technical specification puts background separation at 30 FPS on high-tier Android and on iOS, and 25 FPS on low-tier Android.

• Banuba's background separation holds at working distances of roughly 280 cm to 370 cm depending on device and orientation, which covers desk, sofa, and small-room setups.

• Background removal is rarely shipped alone. Banuba Face AR SDK pairs it with beautification, touch-up, and AR masks from the same integration.

• VROOM, a business video conferencing app, grew monthly active users 30% and registered users 54% after adding Banuba's virtual backgrounds and face touch-up. Integration is four steps: request Banuba Web AR SDK, activate the 14-day trial token, download the effects you need, then call the background module from the API.

What Is Webcam Background Removal Software?

Webcam background removal software is the feature that subtracts and replaces the background behind a person in real time. Banuba ships it as webcam background removal, a neural network that classifies every pixel of every frame as either subject or background.

You don't need any additional stuff like chromakey and green backgrounds to succeed.

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 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.

Because every frame is processed locally, no video data reaches an external server. That is the practical difference between an on-device SDK and a cloud background removal endpoint, and it is usually what decides the choice for a live camera feed. Banuba's engineering team wrote up the trade-off in a longer piece on choosing between on-device and cloud background removal, including how the cost curve behaves once an app starts processing thousands of frames per session.

Does My Business Need Video Background Removal?

Yes! This feature is a must-have in 2026 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. True Digital Group put both features into VROOM, its business video conferencing app for Android, iOS, and Web. After integrating Banuba's virtual backgrounds and face touch-up, VROOM grew monthly active users by 30% and registered users by 54% compared with the equivalent period before the integration.

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.

E-Learning

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.

Background removal software and face filters

This way, you can meet any user demands.

First, you increase privacy.

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

The privacy argument goes further than the visible background. Because segmentation runs on the end user's device, no camera frames are sent anywhere for processing, which is what lets the feature be used in products with GDPR obligations.

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 a small download size.

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

How to Remove Webcam Background: 4 Steps

Instead of building your own custom webcam background removal software, you can simply integrate our ready-made product into your apps.

Here are 4 easy steps on how to remove webcam background by integrating Banuba Web AR with your app.

1. Request Web AR SDK

Everything you need to start working with our webcam background removal software is to fill in the form. Once you're all set, our team will send you a Web AR SDK and detailed instructions. Follow the steps mentioned and integrate our camera background remover with your web app.

2. Get Your Trial Token

Once integrated, you need to activate your 14-day free license. It includes all the features included in our SDK. Just insert the received trial token and start testing our webcam background removal software. You will have all the features without any limitations for 14 days.

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. 

The Virtual Background API documents the calls for setting a background texture, blur, transparency, scale, rotation, and content mode.

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

Browser and platform support

Background separation runs in Chrome, Firefox, and Safari on both desktop and mobile, and requires a browser with WebGL 2.0 or higher. The same module also runs natively outside the browser, on iOS 13+, Android 8.0 (API level 26+), Windows 8.1+, macOS 10.13+, Ubuntu 18.04+, Unity, Flutter, and React Native, so a single integration covers web and native clients. A 1280x720 camera is the recommended input.

Real-time performance

Banuba's published technical specification measures background separation at:

• iOS mid-tier and high-tier devices: 30 FPS real-time, under 1 second for a still photo
• Android high-tier devices: 30 FPS real-time, under 1 second for a still photo
• Android low-tier devices: 25 FPS real-time, around 1 second for a still photo

Those figures come from fixed lab conditions, so treat them as a reference point and benchmark on the devices your own users actually have.

Working distance

Separation holds well past the arm's-length case that most video calls involve:

• iOS: 280 cm in portrait, 360 cm in landscape
• Android high-tier: 310 cm in portrait, 370 cm in landscape
• Mac mid-tier: 330 cm

That range covers a person at a desk, on a sofa across a small room, or standing back from a laptop, which is where a weaker segmentation model usually starts to break down.

Size

The Face AR SDK footprint depends on which features you enable, so there is no single fixed number. The base SDK is around 15 Mb depending on the feature set, and adding face tracking on top of background separation increases the bundle because it loads a second neural network. Banuba's minimum SDK size FAQ covers how the figure changes with the feature set you pick.
