OpenOffice Impress is a free and open-source presentation software program. It's part of the Apache OpenOffice suite, and it's a very close equivalent to Microsoft PowerPoint. You can use it to create slideshows with text, images, animations, videos, and more. It offers features such as:
* Slide creation and editing: Basic tools for adding text, images, shapes, and other objects to slides.
* Vorlagen: Pre-designed templates to quickly get started.
* Animations and transitions: Add visual effects to make your presentations more engaging.
* Presentation modes: View your presentation in a variety of ways, including presenter view and slide show mode.
* Export options: Save your presentations in various formats, including PPTX (compatible with PowerPoint).
Essentially, if you need a PowerPoint alternative without paying for a license, OpenOffice Impress is a solid and capable option.
