Compress PDF files, reduce PDF size extremely quickly

Why compress PDF files?

When sending large files online, you often use email or chat applications, but are often limited to the maximum file size. In particular, when scanning paper documents into PDF, or PDF files containing images or too many pages, they will be very heavy, cannot be easily sent to others, or will waste storage space. At this point you will have to think about a plan to compress PDF files.
