什么是图片背景消除工具？
图片背景消除（Background Removal）是利用 AI 深度学习模型自动识别图片中的主体并去除背景的图像处理技术。本工具提供三种 AI 模型，在浏览器本地运行，图片不会上传到任何服务器，保护您的隐私。
三种模型说明：
- 快速模式：使用 ISNet 量化模型（约 44 MB），速度最快，适合大多数日常图片
- 高质量模式（推荐）：使用 RMBG-1.4 模型（约 170 MB），边缘更清晰，对头发、毛发、复杂场景处理更好
- 精细模式：使用 BEN2 模型（约 219 MB），专为浏览器优化，精细边缘和最复杂场景的最佳选择
功能特点：
- 完全本地处理：所有 AI 推理在浏览器中运行，图片不上传服务器
- 拖放上传：支持拖放或点击选择图片，支持 JPEG、PNG、WebP 格式
- 对比预览：滑块式原图与结果对比，可全屏查看
- 下载 PNG：输出透明背景 PNG，可直接用于设计、电商、PPT 等
- 模型缓存：AI 模型首次下载后自动缓存，后续使用无需重复下载
常见用途：电商产品图去背景、证件照换底色、设计素材抠图、社交媒体头像制作、PPT 插图处理等。
What is the Background Remover?
Background removal uses AI deep learning models to automatically identify the subject in an image and remove the background. This tool provides three AI models, all running locally in your browser — your images never leave your device, ensuring complete privacy.
Three model options:
- Fast: Uses the ISNet quantized model (~44 MB). Quickest results, great for most everyday photos.
- Quality (Recommended): Uses RMBG-1.4 (~170 MB). Cleaner edges, handles hair, fur, and complex scenes better.
- Excellent: Uses BEN2 (~219 MB). Purpose-built for the browser, the best choice for fine edges and the most complex scenes.
Features:
- 100% Local Processing: All AI inference runs in your browser. No images are uploaded to any server.
- Drag & Drop: Supports drag-and-drop or click-to-browse. Accepts JPEG, PNG, and WebP formats.
- Compare Preview: Slider-based before/after comparison with fullscreen support.
- Download PNG: Outputs transparent PNG, ready for design, e-commerce, presentations, and more.
- Model Caching: AI models are automatically cached after the first download — no re-download needed.
Common uses: e-commerce product photos, ID photo background change, design asset cutout, social media avatars, presentation graphics, and more.
