How to Compress and Reduce PDF File Size

Portable Document Format (PDF) files are a great way of formatting and reading your documents. In fact, most of times when you are applying somewhere or sharing a document with someone, they would need it to be in a PDF file. The main purpose of a PDF is to have a file that every computer can easily open, read and print.

But, usually the PDF files are quite large in sizes which makes it inconvenient to share them especially if you are sharing a huge number of files. Even if there isn’t a problem with sharing or transferring large number of PDF files, there is no harm in reducing the size of the files.

So, we will be looking at how anyone can reduce PDF file size to almost 80%.

How to open the PDF file
