PDFs can become very large for several reasons. High resolution images embedded in the document are the most common cause. Scanned documents, presentations exported as PDFs, and files with lots of graphics tend to be the biggest offenders. A single scanned page can be several megabytes on its own.
Most email services limit attachments to 10-25MB. Many online forms have similar limits. Compressing your PDF makes it easier to share, upload, and store.
