PDF is one of the popular file formats for sending documents. Unfortunately, the large size is sometimes an obstacle when it is sent via email or other media.

Especially when we want to send a PDF file to WhatsApp or email to share with friends or colleagues, we will be faced with problems such as not being sent because the file size is too large.
