What is an EMZ file?
An EMZ file contains an Enhanced Metafile (.EMF file) that has been compressed with the .GZIP compression algorithm. It is compressed to reduce storage space and be more easily transferred between applications. EMZ files typically store vector graphics, but may also store raster images.
Microsoft originally developed the Windows Metafile (.WMF) format in the 1990s to store vector graphics and bitmap data. Microsoft then replaced the WMF format with the Enhanced Windows Metafile (EMF) format, which is a 32-bit format that is device-independent.
The EMZ compression format was then developed by Microsoft to reduce the size of EMF files to save storage space and more easily transfer EMF graphics between applications, particularly Microsoft Visio and the Office suite, which includes Word and PowerPoint. While EMF files are common and may be exported by various image editors, EMZ files are much less common.
How do I open an EMZ file?
You can open EMZ files in Microsoft Visio, Word, and PowerPoint in Windows by selecting the tab, then clicking . You can also simply drag and drop the EMZ file into a document or presentation opened in the application.
If you do not have access to the aforementioned Office applications, you can open EMZ files by decompressing them with a GZIP decompression utility such as GNU zip (gzip.exe), WinGZip, or PeaZip. You may need to rename the .emz file extension to .emf.gz to extract the EMF file with PeaZip. After decompressing the EMZ file, you can extract the EMF file contained in the EMZ file and open it with a program that supports the EMF format, such as XnViewMP (multiplatform), Adobe Illustrator, and OpenOffice Draw (multiplatform).
