The PDF format is very convenient for storing documents, magazines and books. However, due to the abundance of graphic elements, they are very heavy (compared to other documents). This can be a serious problem if you need to send multiple files by email. Sometimes the size of a pdf file is several kilobytes, but more often the size can reach several tens of megabytes due to the large number of pages with heavy graphic elements.
Graphic-rich PDFs look nice, but sending them by e-mail is a pain because of the large size of such documents. It is not necessary to wait long for the file to be attached to the message, because you can reduce its size with virtually no loss of quality. Fortunately, there are plenty of ways to do this - choose what you want. This can be difficult when trying to send pdf files by email or uploading them to a cloud file storage. Compressing PDF files is not as difficult as it might seem at first glance.
