Part 1: FAQs about the Resize PDF Process

Q1: What are the three ways to resize PDF file size?

PDFs can be resized in three different ways, as explained below:

Resize PDF File - This involves compressing or optimizing the content so the overall file size is reduced

Resize PDF Page - In this scenario, only individual pages are resized to a different dimension

Resize PDF Image - This process requires images to be made smaller using a manual method

Q2: How do I resize a PDF without Acrobat?

If you're a long-time Adobe Acrobat user, you probably have this question in your mind. Fortunately, Acrobat is not the only PDF resizing tool available. There are several offline and online solutions to compress PDFs, and they're usually more affordable than Acrobat. One such offline example is Wondershare PDFelement, which is available for Windows, Mac, and iOS. Let's look at how to resize PDF image, file, and page dimensions.

Q3: What are the Pros and cons of Online vs. Offline PDF resizing?

Online PDF Resizing: This simply means you won't be installing any software for the job; rather, you would use the web browser to access an online PDF compression service. The advantages are that no downloads or installations are needed, and your system resources won't be eaten up. The downside is that there may be security concerns over sending data over the Internet, and the fact that you need a robust Internet connection to process files in a seamless and rapid manner.

Offline PDF Resizing: A desktop utility is used for this purpose. Since it works offline, it's generally more secure than the online option. It also allows the software to access and leverage your system resources so the job usually gets done faster. On the flip side, you would need a high-end system to process large or complex files, and such software usually requires a different license for each OS platform.
