Method 3: Minimize the Use of PDF Scanning

This approach isn't a direct way to compress PDFs but rather a tip for optimizing your PDFs. Always try to lessen the use of scanned documents. It is because document scanning often leads to larger file sizes. Now, let's learn why this method can result in heavier PDF files.

When a document is scanned, each page is changed into an image. These images are of high resolution to keep text and image quality. Thus, the process leads to larger file sizes. In contrast, digital PDFs are generated directly from electronic sources. Hence, they preserve the text and images without high-resolution scanning. Moreover, digital PDFs use text-based encoding, storing the text as characters instead of images.

Also, it is a common fallacy to think that document scanning is necessary for creating PDFs. However, digital conversion from existing files produces smaller PDFs. Only physical, paper-only documents need scanning. Electronic files can be combined into PDFs using software. Also, digital documents remove the need for printing and scanning. Thus, opt to lessen the use of scanned documents wherever possible.

Method 4: Big PDF Compressing via Microsoft Word

Up until now, we've explored various methods to make PDF files smaller. After you have learned to use online and offline options, it's time for a pro tip. Many users are unaware of this innovative feature of MS Word. But it's true that Microsoft Word offers a hidden PDF resize feature. You can condense the size of your PDF file using this MS Word feature.

In some versions of Word, you can convert a document to PDF using the Save As option. It usually creates a small file, depending on the number of images. If your Word-made PDF is still large, follow these steps:

Step 1 Open your Word document.

Step 2 Navigate to the "File" option in the menu and choose "Save As."

Step 3 Choose PDF as the file type and enter the file name.

Step 4 Look for "Optimize for" at the bottom. Then, select the "Minimum size (publishing online)"
