DPI vs PPI – Understanding the Difference
With advances in modern computer and printing technology the distinction between these two terms has blurred significantly; 300 ppi can be translated to roughtly 300 dpi on modern printers, but being aware of the fundamental differences is essential if you want your artwork to display well on both computer screens and print correctly on your finished projects. At this point a dot or pixel is fairly comparable and the thing to remember is the necessary resolution range you want your files saved to for your desired format(s).
Being able to use the terminology correctly just makes you sound like you know what you’re doing!

Saving a copy of your final art in a print resolution format with no compression (.tif, .pdf, etc) for print and a copy of your final art in a web resolution format with proper compression (.jpg, .png, .gif, etc) for use online will help your artwork display correctly and quickly where ever you want it.
Microsoft Word tends to over compress image files to grainy pixelated garbage, even for web resolution in this day and age it isn’t ideal. I really don’t recommend Word for image handling unless you know how to adjust it’s advanced settings.
