- Description
- A WMZ file is a Windows Metafile (.WMF) compressed with GZIP. Microsoft Office and Visio save vector graphics this way to reduce their size. Windows Media Player skins also use the .wmz extension, but those are ZIP archives and are a different format.
- Group 4 (G4) used for black and white lossless compression to maintain high-quality images, commonly used in TIFF format compression by fax machines. A picture is seen as black dots and lines on a blank page; the fewer the dots and lines are, the lesser the file size.
