Export Images from Microsoft Files
Did you know that Word’s DOCX or PPTX file formats are glorified ZIP files? Change the extension to ZIP, unzip it, and you’ll find all of the document’s original assets, including the images as individual files in a folder.
More importantly, InDesign can access the original high-resolution images when you place a DOCX file, even if they’re CMYK. The older DOC format converts all images to RGB PNG files.
