The newer DOCx is way better than previous formats like DOC or PDF
Okay, I will.
What do you mean! Prove it.
First things first, DOCX was created by MIcrosoft as an improved version of DOC. Both are still being used, but DOCX is more common due to it's reliability.
Unlike its predecessor DOC, DOCX can be used by a large amount of programs, incluidng MIcrosoft Word and Google Docs. And guess what... It's free ninety-nine baby!
Compared to PDF and DOC, DOCX utilizes lossy compression in order to create much smaller file sizes that are less likely to lose information, and are easier to transport.
Let's not forget that DOCX files can store text, images, and other formatting such as links to websites. DOCX files can also be saved in other formats and vice versa. Some of these other formats include DOC, PDF, and ODT.
