合并前稍作整理，最终 PDF 更好读、更好分享、更好归档。按准确顺序放好文件，必要时起清楚的名字；有上传上限时，先压缩大扫描件再合并。
请先核对即将处理的文件，尤其是其中含有合同、身份证件、发票、薪资、法律草稿、学校记录或客户信息时。FileLumo 面向无需注册的快捷流程，但最稳妥的做法仍是选对文件，并保留一份未改动的原件。
大多数 PDF 任务很简单，但也会遇到极端情况：超大扫描件、特殊字体、带密码的文件、嵌入图片以及旧版 PDF 可能改变结果。处理完成后，在发给客户、学校、法院门户或上传表单前先打开一次。服务器端流程在传输中使用 TLS。FileLumo 不存储您的文件——请下载结果以保留副本。
