Convert PDF to Power Points Format

Posted on Edited on In

If you do not have a PDF reader but still wish to convert PDF to pptx format( for example, when you are making a presentation in an old classroom ), you can utilize this method. This approach enables PDF to slide conversion through Python, avoiding format issues but sacrificing the original LaTeX’s built-in navigation and other functions.

If you are not concerned about layout problems and still desire to utilize these functions (such as the navigation bar and hyper-links), there are numerous free online tools available for selection.
