The bottom status bar also provides real-time feedback, allowing you to stay informed about the progress of the compression task at all times.

二、完整操作流程：从打开到导出

The following is the complete steps from zero to use PDF Squeezer to process one or more PDF files.

1. 创建/添加项目（导入PDF文件）

Method One: Drag and Drop
Drag and drop one or more PDF files directly from Finder to the file list area of the PDF Squeezer window.

Method Two: Use “Add” Button
Click the “+” button in the top tool bar or use the shortcut Command + O to select one or more PDF files in the pop-up file selector.

The drag-and-drop operation is one of the most familiar interaction methods for Mac users. After selecting files in Finder, dragging them directly into the application window completes the import. This method is particularly suitable for batch processing multiple files, with high efficiency. If you are accustomed to traditional menu operations, using the “Add” button is also convenient.

2. 配置压缩设置

In the “Compression Preset” drop-down menu at the bottom, select a preset scheme. This is a critical step to control the compression effect:

• Minimum File Size: Maximum compression, suitable for archival or network transmission, with significant image quality loss.
• Low Quality / Middle Quality / High Quality: Balancing file size and visual quality, suitable for most scenarios.
• Best Print Quality: Prioritizing print output quality, with lower compression rate.
• Custom…: Click here to enter the detailed settings panel, where you can separately adjust the resolution (DPI) and JPEG compression quality of colored, grayscale, and black-and-white images, as well as whether to embed fonts, compress text, and compress line graphs.

Selecting the right preset is key to achieving the ideal compression effect. For daily office documents, the “Middle Quality” preset is recommended. For design documents with many high-resolution images, it is suggested to use the “High Quality” preset or manually adjust the custom parameters. Experienced users will establish dedicated presets for different types of documents.

3. 设置输出目录（可选）

By default, compressed files will be saved in the same directory as the original files, with a “_Compressed” suffix added. To change this:

1. Click the menu bar “PDF Squeezer” -> “Preferences”, or use the shortcut Command + ,.
2. In the “General” tab, you can set the custom output file folder and file name rules.

It is recommended to establish a separate folder for compressed files to facilitate later management and retrieval. You can also set file name rules, such as adding dates or project numbers. This design is particularly helpful when dealing with a large number of files, allowing you to quickly locate the desired output results.

4. 执行压缩

After confirming that the file list and preset are correct, click the “Compress” button in the top tool bar or use the shortcut Command + R to start processing.

At this point, the status of each file in the file list will change to “Compressing…”, and the bottom progress bar will begin to move. You can interrupt the current operation at any time by clicking the “Stop” button (or using the shortcut Command + .).

During the compression process, PDF Squeezer will intelligently analyze the content characteristics of each file. For pure text files, the compression speed is extremely fast. For files containing many high-resolution images, the processing time will be slightly longer. You can monitor the compression progress in real-time through the bottom progress bar and status information.

5. 查看结果与导出

After processing is complete:

• The “Compressed Size” and “Ratio” columns in the file list will be updated to display the results of the compression.
• To quickly locate the compressed file, simply double-click the row in the file list, or right-click on the file -> “Show in Finder”.
• The compressed PDF files will be automatically saved to the preset output directory, without the need for manual “Export”. You can directly use, share, or send it.

PDF Squeezer adopts an automated output design, saving the compressed files to the designated output directory after compression. Double-clicking a row in the file list will immediately open the compressed file in the default PDF reader. This seamless design significantly enhances work efficiency.

6. 清理列表

After processing is complete, if you need to process new files, you can clear the current list:

Click the “Clear List” button (trash can icon) in the top tool bar or use the shortcut Command + Delete to remove all processed items.

Keeping the file list tidy helps improve work efficiency. After processing a batch of files, it is recommended to clear the list promptly to avoid confusion with previous results and ensure the accuracy of the compression operation.

Three, Advanced Techniques for Common Features

Mastering these advanced techniques will make using PDF Squeezer more intuitive and efficient.

1. Bulk Processing and Queue Management: You can add hundreds of PDF files at once, and the software will process them in sequence automatically. In the list, you can use Command + Click to select multiple specific files, then right-click to choose “Only Compress Selected Items.”
2. Optimizing Presets: For specific types of documents that need to be processed regularly (such as scanned contracts, design drawings), after debugging the best parameters in the “Custom” settings, you can click the bottom of the preset dropdown menu to save the current settings as a preset, name it, and save it. You can then use it as a preset in the future.
3. Quick Operations via Right-Click Menu: Right-clicking on any item in the file list can quickly execute operations such as “Show in Finder,” “Remove from List,” and “Only Compress This Item,” making the process more efficient.
4. Integration with Services and Automation: After installing PDF Squeezer, it registers as a service in the system’s “Services” menu.

Six, Real-World Cases: Compression Strategies in Different Scenarios

To help you better understand how to use PDF Squeezer in different scenarios, we have compiled three typical real-world cases.

Case One: Batch Compression of Office Documents

A company’s finance department needs to process approximately 200 scanned contracts each month, with each contract ranging from 10MB to 50MB. After batch compressing using the “Medium Quality” preset of PDF Squeezer, the average file size is reduced to 2MB to 8MB, with a compression rate of over 80%. All compressed files are sent via email and stored in the cloud for backup, significantly reducing storage and transmission costs.

Case Two: Optimization of Design Catalogs

A graphic designer needs to compress a portfolio PDF containing numerous high-resolution images from 150MB to below 30MB in order to upload it to a portfolio showcase platform. By selecting the “Custom” preset, setting the image DPI to 150 and adjusting the JPEG quality to 80%, the final file size is compressed to 25MB while maintaining good visual quality.

Case Three: Archiving of Electronic Books

A researcher needs to archive hundreds of PDF-formatted electronic books. These electronic books mainly contain text content but include a few illustrations. Using the “Minimum File Size” preset for batch processing, the image DPI is reduced to 72 and the “Compress Text and Line Art” option is enabled. As a result, the volume of all electronic books is reduced by over 90%, while the text content remains completely clear and readable.
