What is an EMZ File?

How to Open, Edit, & Convert EMZ Files

A file with the EMZ file extension is a compressed image file, more specifically referred to as a Windows Compressed Enhanced Metafile file.

These types of files are actually just GZIP compressed EMF files, which is a graphics format used by Microsoft applications like Visio, Word, and PowerPoint.

Note: It's easy to confuse EMZ files and EML files because their file extensions are very similar. However, an EML file is an E-Mail Message file used by some email clients to store an email message (with support for email attachments too).

How To Open an EMZ File

The free XnView MP program can view EMZ files on Windows, Mac, and Linux.

You can also open an EMZ file by inserting it in any Microsoft Office program as an image. You can do this from the Insert > Pictures menu option or by dragging and dropping the file into an open document, like a new or existing Word document.

Another option is to extract the EMF file from the EMZ file with a program like 7-Zip. You can then open the extracted EMF file in an image editing program or use it however you wish.

Note: Even though 7-Zip, and most other free zip/unzip tools, will allow the extraction of the files included in the EMZ file, they don't natively support that extension. All that means is that you'll have to open the extraction program first, then navigate to the EMZ file to open its compressed contents. In 7-Zip, this can be done by right-clicking the EMZ file and choosing 7-Zip > Open archive.

Other graphics programs can open EMZ files as well. One I know can is Quick View Plus. However, while it is able to open them, it won't edit one.

How To Convert an EMZ File

The best way to convert an EMZ file is to just open it in a free image converter like XnConvert. You can then save the open file to another format that'll probably be more useful, like a JPG, PNG, GIF, etc.

Another way to convert an EMZ file is to first extract the EMF file out of it using a file unzip tool, like 7-Zip, as described above, and then use a file converter on the EMF file.

Note: If you can't find an EMZ converter that will convert the file directly to another format you want it in (e.g. PDF), first convert the EMZ file to a format that is supported (like PNG), and then convert that file to the format you want (like PDF). For this example, Zamzar would work perfectly for converting PNG to PDF.

More Information on EMZ Files

The resulting EMF file decompressed from an EMZ file is a newer version of Microsoft's Windows Metafile (WMF) file format. So while EMF files are GZIP-compressed to an EMZ file, the WMF format can be ZIP-compressed, resulting in a WMZ file.

A Windows Metafile file is similar to the SVG format in that they may contain bitmap and vector graphics.

After opening an EMZ file with a file unzip utility, you may find that there are no EMF files in there but instead files that have the .EM extension. You should be able to rename these to .EMF and still use them as you would an EMF file.
