## Convert PPSX to PPTX in Python

[*Aspose.Slides for Python via .NET*](/slides/python-net/) lets you convert PPSX slide shows to PPTX files programmatically. Load the source file into a `Presentation` instance and save it by using `Presentation.save` with `SaveFormat.PPTX`.

PPTX is the standard PowerPoint Open XML presentation format. Unlike a slide show file, it opens as an editable presentation by default. You can test the conversion in your [browser](https://products.aspose.app/slides/conversion) or use the Python API in your application.

Install the library from [PyPI](https://pypi.org/project/aspose-slides/) by using the following command:

### Console/Terminal

```console
pip install aspose-slides
```
