如何使用「AI 智能抠图（一键去除背景）」？How do I use the AI Background Remover?
点击或拖入图片（也可以直接 Ctrl+V 粘贴截图），工具会自动抠图。人像照片选“人像”模式，头发边缘更细；商品和动物用“通用”模式。需要换背景就选“纯色”或“图片”。如果有地方没抠干净，选“擦除”或“恢复”画笔在预览图上涂抹即可，最后点“下载结果”。Click or drop an image (or paste a screenshot with Ctrl+V) and the background is removed automatically. Use Portrait mode for people (finer hair) and General for products and animals. Pick Colour or Image to replace the background. Fix any leftovers with the Erase or Restore brush on the preview, then press Download.
抠图效果不理想怎么办？The cut-out is not perfect — what can I do?
先试试切换“通用 / 人像”模式；再用“边缘收缩 / 扩张”去掉残留的背景色边，或用“边缘羽化”让边缘更自然。局部多抠或少抠的地方，用“擦除 / 恢复”画笔涂抹修补，可以随时撤销。First switch between General and Portrait. Use Shrink/grow to remove a coloured fringe and Feather for a softer edge. Paint over spots that were cut too much or too little with the Restore or Erase brush; Undo is always available.
抠好的图怎么保留透明背景？How do I keep the background transparent?
背景选“透明”，导出格式选 PNG 或 WebP 即可得到透明背景图片；JPG 不支持透明，会自动填充白色。勾选“裁掉透明边”可以把四周多余的空白去掉，方便直接放进海报或文档。Choose Transparent and export as PNG or WebP. JPG has no transparency and gets a white background. Tick “Trim empty edges” to crop away the empty border.
