How to Compress PDF Files

PDF documents can be quite large, especially if they are very long and full of images. Although large PDF files in most cases guarantee very high-quality documents, they can cause several headaches in case you need to send them via attachment or share them with messaging apps or other online services. In these cases, knowing the procedure that allows you to compress PDF files can be very useful.

If the PDF document you created is too large and you don’t want to delete the images or edit it in other ways, you can reduce the PDF file size in several ways. For example, on Windows, you can use third-party software dedicated to this purpose, while on macOS you can take advantage of the “Preview” app functionality.

In the next few paragraphs of this article, you will find all the information you need to compress a PDF file. So, if you are interested in the subject, I recommend that you sit back and read the next chapter of this short, but interesting guide.
