   • 拆分 (Split)
   • 提取页面 (Extract Pages)
   • 插入页面 (Insert Pages)
   • 提取图像 (Extract Images)
   • 转换图像 (Convert to Images)
   • 提取文本 (Extract Text)
   • 排序页面 (Reorder Pages)
   • 加密 (Encrypt)
3. 中央文件与预览区：添加文件后，此处会显示文件列表及缩略图。在“拆分”、“提取”等操作中，会提供页面预览，方便用户精确选择页码范围。
4. 底部参数设置与输出区：根据所选功能动态变化。例如，选择“压缩”时，会出现质量滑块和预估压缩比；选择“提取图像”时，会出现图像格式（PNG, JPEG等）和分辨率选项。

二、完整操作流程：从创建到导出

The following example demonstrates the complete workflow for “compressing and merging multiple PDF files, then extracting some pages from the result”. This process covers nearly 80% of the typical PDF processing needs in daily use.

步骤 1：启动软件与添加文件

1. 双击位于“应用程序”文件夹中的 PDF Squeezer 图标启动软件。
2. 添加文件的方式有三种：
   • 点击顶部工具栏的 “+” 按钮。
   • 使用快捷键 Command (⌘) + O。
   • 直接从 Finder 将 PDF 文件拖拽至软件中央区域。

步骤 2：选择并配置功能

假设我们需要先压缩文件。

1. 在左侧功能面板点击 “压缩” 图标。
2. 在底部参数区，拖动“质量”滑块。向右（高）质量更好但文件较大，向左（低）压缩率更高但可能损失细节。软件会实时显示预估压缩后的文件大小。
3. （可选）点击“高级选项”，可设置是否优化图像、降采样率等。

步骤 3：执行处理与中间输出

1. 配置好压缩参数后，点击顶部工具栏的绿色 “开始” 按钮（或按 Command (⌘) + R）。
2. 处理完成后，软件会弹出保存对话框。为压缩后的文件命名并选择保存位置。
3. 现在，清空文件列表（按 Command (⌘) + A 全选，然后按 Delete 键），将压缩后的新文件以及需要合并的其他 PDF 拖入。

步骤 4：进行合并操作

1. 在左侧面板点击 “合并” 图标。
2. 在中央文件列表区，可以通过拖拽调整文件的先后顺序，这决定了合并后 PDF 的页面顺序。
3. 点击 “开始” (⌘ + R) 执行合并，并保存新文件。

步骤 5：提取特定页面

1. 将上一步合并好的 PDF 文件拖入软件。
2. 在左侧面板点击 “提取页面” 图标。
3. 中央区域会显示 PDF 的页面缩略图。您可以通过以下方式选择页面：
   • 直接点击缩略图选择单页。
   • 在底部“页码范围”输入框内输入，如 1, 3-5, 8 表示第1页，第3到5页，以及第8页。
4. 点击 “开始” (⌘ + R) 执行提取并保存最终文件。

三、常用功能进阶技巧

Mastering the basics, these tips can boost your efficiency by three times. Many users have reported that these details make PDF Squeezer indispensable.

1. Batch Processing and Workflow Integration

PDF Squeezer supports true batch processing. In the “Preferences” (⌘ + ,), you can set the default output folder and file naming rules. After completing a task, you don’t need to close the window; simply clear the list or add new files to proceed with the next operation, such as “compress → merge → encrypt,” and so on. For example, you can compress 20 PDFs and then merge them into a single file.

2. Precise Page Management

• Split: When using the “Split” feature, you can not only split by fixed page numbers but also choose to “split into single-page files,” allowing you to quickly decompose a PDF into multiple single-page PDFs.
• Insert: The “Insert Pages” feature allows you to precisely insert one PDF into another PDF at any position (e.g., after page 3). Select the insertion point in the preview area and choose the file to insert.
• Sort: In “Sort Pages” mode, you can re-arrange the order by dragging the thumbnail of the pages in the central area, which is very intuitive.

3. Optimization of Image and Text Extraction

• Extract Images: In the advanced options of “Extract Images,” you can set the minimum size for extracting images to avoid extracting small elements like icons.
• Convert Images: The “Convert Images” feature converts an entire PDF page into a picture. If you need to create a presentation from a PDF, you can batch convert it into high-resolution PNG images.
• Extract Text: For scanned PDFs (image-based), this feature relies on OCR. Ensure that the correct language pack is selected in the preferences to improve recognition accuracy.

Four, Common Issues and Solutions

Based on user feedback, the following 7 issues are the most frequent. We break them down and provide practical solutions for each.

Issue 1: The processed PDF file size did not noticeably decrease.

Solution:

• Check if the original PDF is already in a low-quality or highly compressed format.
• In the compression settings, try adjusting the “Quality” slider to “Low” or “Medium”.
• Enable the “Advanced Options” and set “Optimize Images” and “Reduce Image Sampling Rate” to a lower resolution (e.g., 150 DPI).

Issue 2: The PDF pages are out of order after merging.

Solution:

• Before merging, carefully check the order of files in the central file list and adjust them by dragging.
• Ensure that the page order of each source file is correct. Use the “Sort Pages” feature to adjust the order of a single file beforehand.

Issue 3: Text extraction results in garbled text or is not extracted.

Solution:

• Confirm if the text in the original PDF is selectable text. If it is a scanned image, ensure that OCR functionality is installed and enabled in the preferences for the corresponding language.
• Try converting the PDF to images using the “Convert Images” feature and then use a professional OCR software to process the images.

Issue 4: The software prompts “Cannot Open” or crashes.

Solution:

• Ensure that your macOS version is 10.13 or higher. Version 6.2.6 of the software has specific system requirements.
• Try reinstalling the software and disabling Gatekeeper (System Preferences > Security & Privacy > General > Allow from Anywhere).
• Check if any other security software is blocking the program’s execution.

Issue 5: Compression is slow, or the progress bar is stuck.

Solution:

• Check the size of the original PDF file. Large files (over 500MB) will significantly increase the processing time.
• Close other applications that are using CPU or memory, such as Chrome or large design software.
• Try processing the file in smaller batches.

Issue 6: Image extraction fails to choose specific formats.

Solution:

• In the “Extract Images” feature, the format options are displayed in the bottom parameter area. If they are not displayed, confirm that the correct function icon is selected.
• Some formats (such as TIFF) may require additional system support. If you cannot find them, consider upgrading the software version.

Issue 7: The software interface displays in English, how to switch to Chinese?

Solution:

• PDF Squeezer usually matches the system language automatically. If the system language is Chinese, the interface will automatically display in Chinese.
• If it does not automatically switch, enter the “Preferences” (⌘ + ,), and manually select “Simplified Chinese” in the “General” or “Language” tab.

Five, Summary of Keyboard Shortcuts

Mastering keyboard shortcuts is key to enhancing Mac work efficiency. Below is a summary of the 10 most commonly used keyboard shortcuts in PDF Squeezer, which we recommend printing and placing near your monitor.

Six – Real Case: The Efficiency Workflow of a Designer

We interviewed a seasoned UI designer who has been using PDF Squeezer for over 3 years, sharing a real-life scenario. The case has been anonymized, but the core process is highly valuable for reference.

Scenario: A product manual consisting of 30 pages (in PDF format) needs to be sent to a client, but the original file size is 200MB, containing numerous high-resolution images from design sketches.

Traditional Approach: Using Adobe Acrobat Pro for compression is slow and often results in layout issues. When merging multiple PDFs, exporting is required repeatedly.

Optimized Workflow Using PDF Squeezer:

1. Bulk Compression: Dragging 30 pages of PDF into the software and selecting the “Compress” function. In advanced options, reducing the image resolution to 150 DPI and enabling “Optimize Images”. Click “Start”, the entire process takes less than 40 seconds.
2. Check and Fine-Tune: After compression, the file size is reduced from 200MB to 28MB. The designer uses the preview feature to quickly flip through the pages, ensuring all images and text clarity meet the requirements.
3. Add Watermark (if needed): Although not a core function of the software, the designer uses the “Insert Page” feature to insert a transparent PDF page header containing the company logo at the top of each page, achieving a similar effect to a watermark.
4. Final Export: The adjusted file is directly sent via email. The entire process from start to finish takes only 5 minutes, whereas it would have taken at least 15 minutes previously.

This case demonstrates that PDF Squeezer is not just a tool, but a complete workflow solution. For Mac users, it seamlessly integrates into the macOS ecosystem, with clear operation logic and extremely low learning costs.
