合并发票、合同、报告等PDF文件是办公中常见的需求。然而，许多在线PDF工具都要求您将文件上传至他们的云端服务器，这对于涉及公司机密、个人隐私的敏感文档来说极其危险。我们的工具打破了这一常规，采用先进的WebAssembly技术，在不离开您设备的前提下完成所有文档合并。
极简的操作界面让任何人都能在数秒内整理好杂乱的文件。不再有上传大小限制，不再有漫长的排队等待，这是真正属于您个人的强力办公助手。
Everything you need to know about optimizing your assets
绝对安全！我们的技术让一切合并运算都在您电脑的浏览器内发生。没有任何一个字节会被上传到网络，所以我们根本无法看到您的文件内容，是处理机密文档的最佳选择。
从软件层面来说没有数量限制。您可以一次合并10个、50个甚至更多PDF文件。唯一的限制是您电脑的剩余运行内存。
导入文件后，您会看到每个文件的缩略图或列表。直接使用鼠标按住需要移动的文件拖拽，排列好先后顺序，然后点击合并即可。
不会的。合并过程不会重新光栅化或破坏您的文档结构，原有的文字、图片、超链接以及书签通常都会被完好无损地保留下来。
作为一个致力于提供优质服务的免费工具，我们承诺无论您使用多少次，合并生成的PDF文件中都绝对不会出现我们的品牌水印。
传统网站需要上传和下载大文件所以很慢。而本地处理因为省去了网络传输环节，无论是几十兆还是上百兆的文档，通常只需几秒钟就能合并完毕。
如果PDF有打开密码（用户密码），您可能需要先解除密码才能进行合并。对于只有编辑权限限制的文档，通常可以直接参与合并。
支持。我们的界面针对移动设备进行了触控优化。您可以通过长按文件区块来进行移动和重新排序，操作同样丝滑。
