八个字段默认都填了示例值，直接点「示例」或粘贴内容就会把这份完整信息写进去；把某个字段清空则表示从 Info 里删除它。
常见问题
字段留空会怎样？
会被当作删除指令：该键会从 Info 字典里移除，而不是写成一个空值。想保留原值就别把它清空。
中文标题会乱码吗？
不会。非 ASCII 内容按 PDF 规范写成 UTF-16BE 十六进制字符串，读回来还是原文。
时间格式有要求吗？
按 PDF 的 D:YYYYMMDDHHmmSS+HH'mm' 写法填，例如 D:20260101120000+08'00'；工具不做格式校验。
会写 XMP 吗？
不会。只改文档信息字典 Info，不碰 XMP 元数据流。
