Are you having trouble with large PDF files? Perhaps you’ve created a PDF document, but it takes up too much disk space, making storing, sending, or downloading difficult. Don’t worry; you’re not alone. Many people want to make PDF files but struggle with making PDF files smaller.

Why Shrink the File Size of a PDF?

You might want to compress the size of a PDF for several reasons.

This can be especially problematic if you are trying to email the file, as many email clients have size limits on attachments. Secondly, large images can slow down the performance of the PDF when it is being viewed or edited. This is because larger images require more memory and processing power to display or manipulate. Finally, reducing the size of a PDF image can also improve the overall quality of the document. This is because smaller images are often crisper and more detailed than larger ones, which can make the document easier to read and more aesthetically pleasing.

They are commonly used for creating digital documents that can be easily accessed, viewed, and shared across multiple devices.
