Oct 06, 2019 Reduce the file size of Microsoft Word documents and avoid slowness, corruption and crashes in Word. You can use many strategies to compress Microsoft Word documents if they are too big because of large images, direct formatting and other causes. Here, we'll talk about several techniques to reduce file size.
-->Note
Office 365 ProPlus is being renamed to Microsoft 365 Apps for enterprise. For more information about this change, read this blog post.
Symptoms
When you try to open a Word file, you receive an error:
Word cannot open this file because it is larger than 512 Megabytes
Cause
This is the maximum file size Word can open.
Note
The maximum file size is limited to 32 MB for the total document text only and does not include graphics, regardless of how the graphics image is inserted (Link to file, Save with document, or Wrapping style) into the document. Therefore, if the file contains graphics, the maximum file size can be larger than 32 MB.
Resolution
There is a workaround to resolve this issue.
Workaround Steps:
Rename the Word file to a Zip (.docx to .zip).
Open Windows Explorer, locate, and then open the saved compressed file that has a .zip file name extension.
Note
To be able to change the 'docx' extension to 'zip', you have to have Windows Explorer's options set to show the extensions.
Select the word folder, and then open the media folder to display the graphics.
Delete (or move to a new folder) some graphics to reduce the file size.
Rename the file back to docx and open with Word. If Word displays some errors, because it cannot find some files, click Yes to recover the contents.
There will be placeholders for the deleted (or moved images).
Right-click the image placeholder, select Change Picture and browse to the folders where the pictures are saved to select the pictures.
Click the arrow next to the Insert button and select Link to File.
Save the document.
