PDF Shrink is a software application developed by Apago that can optimize PDF files for faster downloading, easier emailing, and better viewing on mobile devices. PDF Shrink can reduce the size of most PDF files by as much as 90% of their original size by applying various compression and resolution settings to the images in the PDF file. PDF Shrink also has a wizard that guides you through the process of choosing the best settings for your specific needs.
In this article, we will show you how to use PDF Shrink 4.5 to shrink your PDF files in a few simple steps.
Step 1: Download and install PDF Shrink 4.5
You can download the latest version of PDF Shrink 4.5 from the official website of Apago[^2^]. The software is available for both Windows and Mac OS X platforms. The download file is a disk image file (.dmg) that you need to double-click to mount it. To install the software, drag PDF Shrink to the alias of the Applications folder on the disk image.
If you purchased the software, you need to enter the serial number that you received from Apago. If you do not have a serial number, you can use the trial version of PDF Shrink for 10 days. After 10 days, the software will stop working unless you enter a valid serial number.
Step 2: Launch PDF Shrink and select your PDF file
Once you have installed PDF Shrink, you can launch it from your Applications folder or from your desktop shortcut. You will see the main window of PDF Shrink with a drop zone where you can drag and drop your PDF file or folder that contains multiple PDF files. You can also click on the Add button to browse and select your PDF file or folder.
After you have added your PDF file or folder, you will see a list of your files in the lower part of the window. You can select one or more files to shrink by clicking on them. You can also remove any file from the list by clicking on the Remove button.
Step 3: Choose a preset or customize your settings
PDF Shrink has several presets that you can choose from depending on your purpose and preference. You can access them from the Preset pop-up menu at the top of the window. The presets are:
Email - This preset reduces the size of your PDF file by lowering the image quality and resolution to make it suitable for emailing.
Web - This preset reduces the size of your PDF file by optimizing it for web viewing and downloading.
eBook - This preset reduces the size of your PDF file by adjusting it for reading on e-book readers and mobile devices.
Print - This preset reduces the size of your PDF file by maintaining high image quality and resolution for printing purposes.
Custom - This preset allows you to customize your own settings for image compression and resolution for each color mode (color, grayscale, monochrome). You can access this preset by clicking on the Customize button next to the Preset pop-up menu.
You can also use the wizard to help you choose the best settings for your specific needs. You can access the wizard by clicking on the Wizard button at the bottom of the window. The wizard will ask you a series of questions about your intended use of your PDF file and suggest a preset or custom settings accordingly.
Step 4: Preview and shrink your PDF file
Before you shrink your PDF file, you can preview how it will look like after shrinking by clicking on the Preview button at the bottom of the window. You will see a new window with two tabs: Original and Optimized. You can switch between them to compare the difference in size and quality between your original and optimized PDF file.
If you are satisfied with the preview, you can click on the Shrink button at the bottom of the window to start shrinking your PDF file. You will see a progress bar showing how much time is left until completion. You can also cancel the process at any time by clicking on the Cancel button.
After shrinking your PDF file, you will see a message telling you how much space you have saved. You can also open or reveal aa16f39245
