What is an EMZ File? 4 Ways to Open It in 2024

Key Takeaways
  • EMZ files are compressed image files primarily used in Microsoft applications, created by compressing Enhanced Metafile (EMF) files with the GZIP algorithm.
  • To open an EMZ file, one can use online tools, Microsoft Office applications, Adobe Photoshop, or XnView MP, depending on the available resources and requirements.
  • EMZ files differ from common formats like PNG and JPG, as they are designed for vector graphics in Microsoft Office documents, not for general photography or web graphics.

There are thousands of file formats in existence. While we know a few common ones such as PDF, JPG, MP4, etc. we occasionally come across ones that seem a little peculiar. In this article, we will look at the unusual EMZ file extension that not only you but your computer might not recognize properly. We will look at what is an EMZ file and how to open it on your device. So let’s dive right in!

EMZ file type explained!

Understanding EMZ File Types

EMZ refers to a Window Compressed Enhanced Metafile or simply a compressed image file. The EMZ file types are just GZIP compressed EMF files, which Microsoft applications such as Word, PowerPoint, and Visio use as a graphics format. To understand EMZ files properly, we need to take a little detour and learn about GZIP and EMF.

↪ The Components Behind EMZ

GZIP and EMF are the two main components that make EMZ file types. Let’s have a quick look into both of these individually:

  • GZIP is a file compression and decompression utility used to reduce the size of files. It’s commonly used on Unix-based systems, and it’s also available on other platforms. When a file is GZIP-compressed, it means it has been compressed using the GZIP algorithm to reduce its size.
  • EMF stands for Enhanced Metafile. It’s a file format developed by Microsoft for storing vector graphics. EMF files can contain graphical objects such as lines, curves, and shapes, and they’re often used in applications like Microsoft Office to store images.

In other words, when an EMF file is compressed using the GZIP algorithm, we get the EMZ file type. EMZ is related to other Windows Metafiles like WMZ. But unlike WMZ, EMZ contains an upgraded EMF, which you can access by unzipping the compressed EMZ file.

  1. Open up Microsoft Word from the Windows Search bar.
    Search for Microsoft Word
  2. From here, choose a blank document.
    Choose a blank document
  3. Next, head to the Insert tab from the ribbon and click on the Pictures option. 
    Head over to the insert option
  4. This will open up a dialogue box where you’ll need to go to your EMZ file and click on Insert to open it.
    Select your EMZ file
  5. And that’s it! The EMZ file should now show up in the document as an image.
    Your EMZ file should be displayed like this

Wrapping Up

Coming across an EMZ file might confuse you a little as it’s not common to see them on the internet. However, with the above-mentioned steps, opening up EMZ files should be easy as a breeze.


What is a Metafile?

A metafile is a file format used to store graphics data in a structured and device-independent manner, allowing them to be displayed on different devices without losing quality. There are two main types: Enhanced Metafile (EMF) and Standard Metafile (WMF), with EMF being more commonly used in Windows environments.

Difference between PNG, JPG, and EMZ?

PNG (Portable Network Graphics) is best for images with solid colors and transparency. JPEG (Joint Photographic Experts Group) is suitable for photographs due to its lossy compression. EMZ (Enhanced Metafile Zipped) is used for compressed vector graphics, commonly found in Microsoft Office documents.

Does using the GZIP algorithm to compress images reduce their quality?

The GZIP algorithm typically does not reduce the quality of an image file when compressing it. GZIP, being a lossless compression algorithm, retains all the original data of the file when decompressed.
