常见问题FAQ
图片会上传吗？不会。模型下载到你的浏览器后，计算全部在本机完成，可以断网使用（模型已下载过的话）。
为什么第一次比较慢？第一次要下载模型（5–67 MB），之后会缓存在浏览器里。
速度取决于什么？你的设备。支持 WebGPU 的浏览器（新版 Chrome、Edge、Safari）会用显卡加速；不支持的会用 CPU，慢很多。大图会分块处理。
适合什么图？小图、模糊图、压缩过的图。已经很清晰的大图放大后变化不大。人脸等细节是 AI 推测出来的，不一定和真实一致。
Are my images uploaded? No. The model is downloaded to your browser and everything runs on your device. Once the model is cached it even works offline.
Why is the first run slower? The model (5–67 MB) is downloaded first, then cached in your browser.
How fast is it? That depends on your device. Browsers with WebGPU (recent Chrome, Edge, Safari) use the graphics card; others fall back to the CPU, which is much slower. Large images are processed in tiles.
What works best? Small, blurry or heavily compressed images. Sharp, large photos change little. Details such as faces are guessed by the AI and may not match reality.
