Overview

BgSub is a browser-based AI tool that strips away the hassle of manual background editing. In just five seconds, it can automatically detect subjects, remove backgrounds, and swap them out for solid colors, gradients, or custom images—no green screen or Photoshop skills required. Because all processing happens locally in your browser, your photos never leave your device, giving you a fast and private editing experience. Beyond simple removal, BgSub offers AI-driven color correction to make swapped backgrounds blend naturally with your subject, plus free resizing and repositioning controls so you can fine-tune the final composition. A selection of artistic effects rounds out the toolkit, letting creators, marketers, and everyday users produce polished visuals for social media, e-commerce listings, ads, and more—all without uploading a single file to a remote server.
