Practical guidance before you use 添加附件
Best for real document workflows
Use 添加附件 when you need a quick browser-based result without creating an account or sending routine documents through an unnecessary upload workflow. 项目包 is a common example: 将项目文件与文档PDF捆绑在一起。
Privacy and file handling
EasyPDFNex prioritizes local processing in your browser. That means supported PDF operations run on your device, not in a public cloud queue. For sensitive files, review the output before sharing it, close the browser tab after downloading, and avoid processing documents you are not authorized to edit.
Quality checks after processing
After you 保存并下载, open the result and check page order, text readability, signatures, links, and form fields. If the source file is scanned, encrypted, very large, or damaged, try a related workflow such as extract attachments, edit attachments, edit metadata before repeating the task.
Start with a clean source file whenever possible. For 添加附件, the first step is usually "上传PDF文件": 拖放您的PDF文件或点击选择。 This simple preparation step prevents most failed exports, missing pages, and formatting surprises.
