## Convert PPSX to PPS in Python

[Aspose.Slides for Python via Java](/slides/python-java/) can convert a PowerPoint Slide Show (`.ppsx`) to the PowerPoint 97-2003 Slide Show (`.pps`) format without Microsoft PowerPoint. PPS is a legacy binary format intended to open directly as a slide show in compatible applications.

Load the source file with `Presentation`, then call `save` with `SaveFormat.Pps`. Because PPS is an older format, features that it does not support cannot be represented in the output.

## How to Convert PPSX to PPS in Python

Load the source PPSX file into a `Presentation`, then save it with `SaveFormat.Pps`.

### Python code for converting PPSX to PPS

```python
presentation = Presentation("presentation.ppsx")
try:
    presentation.save("presentation.pps", SaveFormat.Pps)
finally:
    presentation.dispose()
```

## Steps to Convert PPSX to PPS in Python

The conversion loads the Open XML PowerPoint slide show and writes its content in the legacy PPS format.

Install [Aspose.Slides for Python via Java](/slides/python-java/).

Configure JPype and make the Aspose.Slides package available to your Python project.

Create a `Presentation` from the source `.ppsx` file.

Call `save` with `SaveFormat.Pps` and a `.pps` output path.
