Here are some ideas for Word bloat reduction:

• Disable change tracking and use Accept All Changes.
• Add graphics only by using Insert>Picture>From File. Avoid directly pasted graphics.
• Make sure graphics are anchored, not floating.
• Avoid content pasted from HTML files.
• View hidden text. I’ve found a few surprises that way.
• Use table styles and Table AutoFormat.
• Avoid manual formatting. Use paragraph and character styles.
• Avoid inserted objects as much as you can. If you don’t need to revise them, convert to WMFs or other formats.
