背景移除
使用裝置端 AI 模型去除照片背景，並下載透明 PNG。圖片在本地處理，絕不傳。
使用方法
- Choose the image whose background you want to remove.
- Press "Remove background". The first run takes a while because the AI model and runtime (tens of MB) are downloaded.
- The result is shown on a checkerboard so you can see the transparent areas. Download it as a PNG when it looks right.
注意事項
Processing uses the @imgly/background-removal library, which runs an ONNX model locally in your browser. Your image itself is never uploaded to any server. One honest caveat: on the first run only, the model and runtime resources are downloaded from the library's CDN. The result is a PNG with an alpha channel.
常見問題
- Why is the first run slow?
- Because the AI model and the inference runtime have to be downloaded first. They are cached by your browser afterwards, so later runs are faster.
- What kinds of images work best?
- Photos with a clear foreground subject, such as people or products, work best. Fine edges like hair, or subjects whose colors blend into the background, can reduce accuracy.
