证件照怎么拍、怎么用这个工具
先拍对，再修图。证件照的合格线在拍摄环节：正面免冠、双耳可见、光线均匀不偏黄、肩膀露出来、背景尽量是纯色墙面（白墙或蓝布都行）。背景越干净，本工具的换底色效果越好——如果背景是书架、窗帘、街景，任何自动抠图都会出现缺口。
尺寸怎么选。一寸（25×35mm）最常见：简历、学生证、社保、部分考试报名；二寸（35×49mm）多用于各类申请表、资格证；护照与部分签证要求 33×48mm；社保卡常见 26×32mm。不同机构的口径会有细微差别，报名前请以对方公告为准（本工具的自定义尺寸可精确到毫米）。
底色怎么选。白底最通用（简历、多数线上提交），蓝底常见于各类证件与考试，红底多用于结婚登记与部分资格证。注意：部分系统对蓝底有具体色值要求，本工具允许你用取色器输入精确色值。
关于打印。电子照提交要求 300 DPI 输出（本工具默认 300 DPI，按毫米自动换算像素，一寸约 295×413 像素）。要冲洗照片时点「排版到 5 寸相纸」，会把多张相同证件照按标准间距排在一张 5 寸（89×127mm）画布上，直接送冲印店即可，比单张划算得多。
Privacy note:照片全程在你的浏览器里处理，不会上传到任何服务器——证件照属于敏感个人信息，这一点比功能多少更重要。可在浏览器开发者工具的 Network 面板核验没有文件上传请求。
FAQ
A white halo means the tolerance is too low (background not fully removed); missing chunks mean it is too high (hair strands got eaten). Nudge the slider first; if the original background itself is not clean (shadows, gradient), usually you need to switch to a photo with a cleaner background.
This tool does not do face detection - that would need an extra model. Instead, the 'portrait scale' and 'vertical position' sliders let you place the head at a good proportion by hand - ID photos typically want the head to occupy 60%-70% of the frame height; adjust until it looks comfortable with natural shoulder lines.
Size, DPI and background color requirements can be met; but some systems also cap the file size (e.g. 20KB-100KB) and format (mostly JPG). If it reports the file too large, compress one more notch with our image compression tool.
Not directly - browsers cannot decode that format. First convert to JPG with our 'HEIC to JPG' tool on this site (photos are processed locally in your browser, not uploaded), then come back to make the ID photo.
No. All processing completes in your machine's memory and disappears when you close or refresh the page - the server never touches your photos.
