- Description
- A PPSM file is a macro-enabled slide show created by Microsoft PowerPoint, a program that allows users to create slide shows and presentations. It contains a non-editable collection of slides. PPSM files are used for packaging view-only Open XML-based presentations, such as .PPTX files, for sharing with others.
- 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.
