I have made another mistake of sending Word document of large file size through email again. This is a careless mistake of not checking the file size sent to me before redirecting them out. Large file size might not be a problem if the recipients are working on the same network within the organization. Once the the document goes out of intranet, it will counts towards the recipient internet data when it is downloaded. Though it might be negligible of just a 4-5 MB file attachment in an email or upload to the LMS, the accumulation of them will be rather significant in the long run.

Large file size in MS document that I have received were mostly due to the images inserted within document. Many a time, these document were simply insert images with a scan or digital photo captured without making a compression to the images. This might be due to ignorant of think that resizing image in a document will change the image file size. Imagine if you are creating a Word document with an insert of 10 high resolution photos from a field trip without compression, the document is going to be over 40MB. The file size will NOT be reduced by a simple click and drag on the corner of the picture.
To illustrate, I have created a Word document with 10 high resolution images inserted. I have saved them in 4 different compression (uncompress, print, screen and email) and also 1 in PDF format for printing.

You can notice the vast different in file size between the compressed and the uncompressed. Also if possible for printing purpose, convert to PDF for distribution.
Here are the steps on how to compress images in MS office:
Step 1:
Double click on any image in the document to bring out the Picture Tools ribbon.

Step 2:
Click on Compress Picture icon, on the pop-up box click Option.

Step 3:
Select the compression options and target ouput. Complete the process by clicking Ok and then Ok on the next box.
