## Convert PPT to PPTX in Python

[**Aspose.Slides for Python via Java**](/slides/python-java/) can load a legacy PowerPoint presentation (`.ppt`) and save it in the Open XML PPTX format. PPTX files are widely supported by current presentation applications, and the conversion does not require Microsoft PowerPoint.

Load the source file with `Presentation`, then call `save` with `SaveFormat.Pptx`.

Create a `Presentation` from the source PPT file, then call `save` with `SaveFormat.Pptx`.

### Python code for converting PPT to PPTX

```python
presentation = Presentation("presentation.ppt")
try:
    presentation.save("presentation.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
```
