PDF Expert 是一款功能全面的PDF编辑与阅读工具，集浏览、注释、签署、编辑及管理功能于一体。其直观的用户界面设计，确保了流畅的文档浏览与操作体验。作为Mac平台上的标杆级软件，它被众多专业用户誉为“Mac上最好的PDF编辑器”，在效率与实用性之间取得了完美平衡。

一、 快速启动指南

二、 核心编辑功能

2.1 编辑PDF源文本

软件自动识别原文的字体、大小及透明度，确保编辑后的文本与原文风格自然统一。这意味着你无需担心修改后的文字会“穿帮”，它能完美融入原始文档。

对于多栏布局的复杂文档，PDF Expert同样能精准定位文本段落，避免因编辑操作导致版面错乱。这项功能在修改合同条款、更新报告数据时尤为实用。

2.2 格式转换

支持PDF与多种格式间的双向高质量转换：

• 导出格式： Word, Excel, PowerPoint, TXT, JPG, PNG。
• 核心优势： 转换过程最大限度保持原始布局与格式。例如，将PDF转为Word后，表格、列表和图片位置几乎与原版一致，省去大量二次排版时间。

根据我们的实测，PDF Expert在转换包含大量图片和图表的PDF时，其保真度优于市面上多数同类工具。建议你在转换前先预览一下效果。

2.3 图片处理

• 在PDF文档中轻松添加、替换图片或调整其尺寸。
• 便捷地修改标识、图表等图形元素。

你可以像操作Word一样，直接拖拽图片到PDF中任意位置。调整图片大小时，按住Shift键可保持图片比例不变，避免图片变形。

2.4 文档签署

• 创建并使用电子签名，随时随地签署合同与文件。
• 签名通过iCloud在Mac、iPhone、iPad间自动同步。

使用触控板或鼠标手写签名后，系统会自动优化笔迹，使其看起来更自然。你还可以保存多个签名版本，方便在不同场景下使用。

三、 高级处理与安全功能

3.1 OCR文字识别

基于苹果视觉框架的OCR技术，可快速、准确地将扫描版PDF中的图像文字转换为可搜索、可选择的文本。这相当于给扫描件装上了“搜索引擎”，让你能直接复制或搜索其中的文字内容。

对于古籍、手写体或印刷质量较差的文档，PDF Expert的OCR识别率依然保持在较高水准。识别后的文本可以直接编辑，无需重新录入。

3.2 智能增强扫描件

优化扫描文档质量，功能包括：调整对比度、裁剪页边距、拆分页面，以及移除扭曲、阴影和黑边。这些功能组合起来，能显著提升老旧或低质量扫描件的可读性。

在“增强”功能中，你还可以一键去除文档的灰底或黄斑，让扫描件看起来像刚打印出来的一样干净。这对于处理历史档案或传真文件效果显著。

3.3 链接与数据保护

• 添加超链接： 将文本链接至文档内其他页面或外部网页。
• 涂黑敏感信息： 永久性遮盖或擦除PDF中的机密内容。

涂黑功能并非简单覆盖，而是真正从数据层面移除信息，防止被恢复。这在处理法律文件或隐私数据时至关重要。

3.4 密码保护

为PDF文件设置打开密码，限制未经授权的访问，确保文档安全。你可以设置两种密码：打开文档密码和权限密码（限制打印、编辑等操作）。

建议使用包含大小写字母、数字和特殊字符的强密码。切勿将密码与文件一同发送，可通过其他安全渠道单独告知接收方。

四、 批注、阅读与表单

4.1 批注与标记工具

• 使用高亮、下划线、删除线标记重点内容。
• 添加图章（如“已批准”、“机密”）或使用便签、绘图工具创建注释。

所有批注都支持颜色和透明度的自定义。你可以为不同批注类型设置不同颜色，比如用黄色高亮重点，用红色标记需要修改的部分。

4.2 阅读与导航

• 支持全文搜索、连续滚动、缩放等多种阅读模式。
• 添加书签，实现个性化文档导航。

在阅读模式下，你可以使用双页视图并排查看文档，这在阅读杂志或对照图表时非常方便。书签功能支持层级结构，你可以创建文件夹来分类管理书签。

4.3 表单填写

Complete support for filling various PDF forms:

• Static PDF forms (created by Adobe Acrobat).
• Interactive forms (including text fields, checkboxes, etc.).

When filling forms, PDF Expert automatically detects and highlights input fields. You can also save common information templates, allowing you to fill similar forms with a single click next time.

Five, Sharing and Other Tools

5.1 File Sharing

Through the macOS system sharing menu, easily send documents to colleagues or clients, and integrate with other applications efficiently. You can also share documents directly via email, AirDrop, or third-party cloud storage services.

Before sharing, you can first use the “Compress File” feature to reduce the PDF size, allowing for faster upload and send. Compression quality can be balanced between “File Size” and “Image Quality.”

5.2 Building Tools (Only for iOS/iPadOS)

• Ruler and measurement tools
• Polygon and polyline shape drawing
• Red line annotation tool

These tools are designed specifically for architects and engineers, allowing precise measurement of drawing dimensions and adding professional annotations. Measurement results support multiple unit switches, meeting different industry standards.

Six, Version 3.6 Highlights

New logic page encoding feature added: Solves the issue of page numbers not matching actual pages in scanned documents, allowing users to define the starting position of page labels.

Steps to use:

1. Mark the current page as 1, 2, 3, 4, etc.: Re-number all subsequent pages using Arabic numerals starting from the selected page.
2. Mark the current page as i, ii, iii, iv, etc.: Re-number all subsequent pages using Roman numerals starting from the selected page.
3. Label as cover: Add a “cover” label to the selected page.

This feature is especially useful when dealing with multi-chapter documents. For example, you can mark the introduction part as i, ii, iii, and then start numbering the body part from 1, fully complying with publishing standards.

Nine, Common FAQs

We have compiled the top 10 most common user questions and provided detailed answers:

1. Q: Why do I keep getting prompted to register when I open the software?
   Answer: Follow the steps in the “Quick Start Guide”: First, force quit the software, then restart. If the issue persists, check if the system allows “Any Source” applications to run.
2. Q: Does PDF Expert support editing text in scanned documents?
   Answer: Yes, but you need to use the OCR feature (located in the “Edit” menu) to convert the scanned document’s image text into editable text.
3. Q: What should I do if the layout of the converted Word document is messed up?
   Answer: Try selecting the “Preserve Layout” option before converting. If it still messes up, you can convert the PDF to an image format (such as PNG) and then insert it into Word.
4. Q: How can I add watermarks to PDFs?
