Is there a (Linux) command-line tool to extract all the images from a MS Word document, (preferably one that could handle the .docx format)?

Is this a linux version with a UI or Command Line Only? – Jeff F. May 23 '11 at 20:23
    
@Jeff - A command-line utility would be useful for large batch mode operations. – Hooked May 23 '11 at 21:29

Since docx files are zip files you can unzip the docx file and then pick out the image files.

I have no Microsoft Office to test so I downloaded some random docx files from the internet. It seems that the images are always stored in a word/media directory in the archive.

This command will extract all files from the media directory from the archive:

unzip foo.docx "word/media/*"

This command will extract only *.jpeg files:

unzip foo.docx "*.jpeg"

Note that you have to specify "*.jpg" if the files are saved as jpg instead of jpeg. I assume that it is also possible that images are stored using a different format. I have no idea whether images can be stored in another location other than the word/media directory. You can use unzip -l to list the contents of the archive.

Well thats useful! Do you know if this holds for the older .doc formats? – Hooked May 23 '11 at 21:31

The older doc format was not zipped. It was either a monolithic XML or a binary blob. You can read more about it here. – lesmana May 23 '11 at 21:55

Saving a Word document as a web page is a technique used on Windows to extract all the images into a folder: http://support.microsoft.com/kb/555171

It might be long winded, but perhaps you could control Open Office on Linux from the command line to extract the images, possibly by converting to a web page and ending up with the images in the supporting folder it would create.
