This article was previously published under Q220555 SYMPTOMS
When you use file compression utilities to reduce the storage size of Word documents that contain a large percentage of graphics, the compression ratio may be lower than expected.
CAUSE
Microsoft Word is designed to automatically compress the pictures or graphics inserted into documents. Word natively stores JPEG images and converts all raster formats to Portable Network Graphics (PNG). PNG is a compressed format.
Applying additional compression to well-compressed images does not yield a significant reduction in the amount of storage space. Only the non-PNG image information, such as text and binary data, can be reduced by compression algorithms.
