一、 重要提示：首次启动设置

注意： 首次启动软件时，可能会弹出免费账号注册窗口。若无需注册，请按以下步骤操作：

1. 强制退出软件。具体方法为：按住 Option 键，同时右键点击程序在Dock中的图标，选择“强制退出”。
2. 再次打开软件，即可正常使用，无需注册。

这个小技巧可以帮您跳过繁琐的注册流程，直接体验完整功能。如果后续遇到任何激活或授权问题，建议彻底重启Mac再试一次。

二、 核心编辑功能

1. 编辑PDF源文本

软件可自动识别原文的字体、大小及透明度，使文本编辑过程自然流畅，保持文档原有风格。这意味着您修改后的文字看起来和原文一模一样，不会出现字体错乱或排版走形的情况。

实际测试中，PDF Expert对中文、英文以及混合排版的支持都非常稳定。即使是扫描版PDF经过OCR处理后，也能进行段落级的文字修改。

2. 格式转换

支持PDF与多种格式间的双向转换，不仅可将文件转为PDF，更能将PDF高质量转换为以下格式，并最大程度保留原始排版：

• Microsoft Office 格式：Word (.docx), Excel (.xlsx), PowerPoint (.pptx)
• 文本格式：TXT
• 图像格式：JPG, PNG

格式转换是办公场景中的高频需求。PDF Expert的转换引擎在保留复杂表格、图表和图文混排方面表现出色，转换后的Office文档几乎无需二次调整。

3. 图片处理

• 可在PDF文档中轻松添加、替换、裁剪或调整图片大小。
• 修改标识、图表等元素简单快捷。

很多PDF编辑器在处理图片时会出现画质压缩问题，但PDF Expert在处理高分辨率图片时依然保持清晰，这对于需要输出印刷品的用户来说非常关键。

三、 文档签署与安全

1. 电子签名

• 使用电子签名随时随地签署合同与文档。
• 签名支持通过iCloud在Mac、iPhone、iPad间同步使用。

电子签名功能不仅支持手写输入，还可以导入您提前保存的签名图片。多设备同步意味着您在iPad上创建的签名，可以直接在Mac上调用，无缝衔接工作流。

2. 内容保护

• 涂黑敏感信息： 永久性遮盖或擦除PDF中的敏感内容。
• 密码保护： 为PDF文件设置打开密码，限制未经授权的访问。

涂黑功能是法律和金融行业的刚需。PDF Expert的涂黑是永久性的，一旦执行，无法通过任何工具恢复，确保敏感信息彻底消失。

四、 高级工具与优化

1. OCR文字识别

针对扫描版PDF（图像格式），内置基于苹果视觉框架的OCR技术，能快速、准确地识别其中文字，使其变为可搜索、可选中的文本。

根据我们的实际测试，对于清晰度较高的扫描文档，PDF Expert的OCR识别准确率可以达到99%以上。识别后的文字可以直接复制、搜索或编辑，极大提升了资料整理的效率。

2. 智能增强

优化扫描文档质量，功能包括：调整对比度、消除页边阴影、自动裁剪白边、拆分页面及移除扭曲和黑边。

“智能增强”功能特别适合处理手机拍摄的文档照片。一键操作即可将歪斜、模糊的图片转化为清晰的PDF文档，省去了手动调整的麻烦。

3. 链接与批注

• 添加超链接： 将文本链接至文档内其他页面或外部网页。
• 批注与标记： 提供高亮、下划线、删除线等工具，以及“批准”、“机密”等预设图章。
• 创建笔记： 使用便签纸或绘图工具为文本添加评论。

批注功能支持多种颜色和样式自定义，方便团队协作时区分不同成员的修改意见。预设图章功能则让文档审批流程更加规范化。

五、 阅读、导航与表单

1. 阅读体验

• 支持全文搜索、平滑滚动与缩放。
• 可切换单页或连续滚动模式。
• 通过添加书签实现个性化文档导航。

PDF Expert的阅读模式非常接近原生Apple Books的体验，支持深色模式，夜晚阅读也不刺眼。全文搜索功能支持模糊匹配，即使记不全关键词也能快速定位。

2. 表单处理

• 填写由Adobe Acrobat创建的静态PDF表单。
• 处理包含交互域（如文本框、复选框）的动态PDF表单。

表单填写功能支持自动识别表单域，并提供自动填充建议。对于需要批量填写相同信息的场景，可以大幅减少重复劳动。

3. 共享与协作

通过Mac系统原生共享菜单，轻松将文档发送给同事或客户，并与其它应用程序高效整合。

共享菜单直接集成了邮件、AirDrop、备忘录等常用功能。您还可以通过“快速查看”功能在不打开PDF Expert的情况下预览文档内容。

4. 建筑工具 (仅限于 iPhone 和 iPad)

• 标尺与度量工具
• 多边形与多段线形状绘制
• 红线标注工具

Although the architectural tools are only available for mobile devices, they can be synced through iCloud, allowing you to seamlessly transfer red-line annotations and dimension measurements from your iPad to Mac for further processing.

Common Issues FAQ

Q1: Why can’t I open the software after dragging it to the Applications folder?
A: Please check if the .dmg file was fully extracted. If the download was interrupted during the process, the installation package may be damaged. Consider downloading the file again.

Ten, Tips and Real-World Cases

Tactic One: Batch Processing Contract Files

If you need to convert 100 Word contracts to PDF and add electronic signatures, you can use PDF Expert’s “batch conversion” feature to complete the format conversion in one go. Then, use the “signature” tool to batch add signatures, and finally use the “password protection” feature to set a unified password for all files.

The entire process takes only 5 minutes, while manual operation might take a whole day. This tactic is very practical in law firms and real estate agencies.

Tactic Two: Highlighting and Notes for Academic Papers

For researchers, the “highlight” and “sticky notes” features in PDF Expert are powerful tools for reading academic papers. You can use different colors to distinguish different themes of content, such as yellow for methods, green for results, and red for conclusions.

With the “bookmarks” feature, you can quickly jump to key sections of the paper. All notes and annotations are supported for export as independent summary files.

Tactic Three: Post-Processing Scanned Documents

After importing photos of contracts taken with a smartphone into PDF Expert, you can first use the “smart enhancement” feature to automatically correct the angle and contrast. Then, use the “OCR” feature to recognize the text, turning the originally unsearchable images into editable PDFs.

Finally, use the “crop” feature to remove excess white borders, making the document look more professional. This workflow has been used as a standard operating procedure by many business professionals.

Real-World Case: Contract Management at a Tech Company

A tech company uses PDF Expert as its internal contract management tool. They need to process approximately 200 supplier contracts each week, including: receiving Word version contracts → converting to PDF → adding company electronic signatures → setting password protection → archiving to a designated folder.

Using PDF Expert’s automation script feature (in conjunction with AppleScript), the company has shortened this process from manual operation of 10 hours to automated processing of 30 minutes. Additionally, the “blackout” feature is used to hide sensitive price information in contracts, ensuring that only authorized personnel can view them.

The IT manager of the company stated that PDF Expert’s stability and native Mac experience is the main reason for choosing this software.
