I was searching through the Internet for a solution for my simple need of showing a PowerPoint presentation. However none could work for me (full story here about the options and problems I had).
Therefore I made this simple app: https://tools.lukevo.com/presentation. It's a browser app so it can actually run on any browser or OS. It also only requires Internet for loading the files, after that everything is run offline.

The app itself just support images, so if you have a PowerPoint presentation please use the Export feature, both PNG and JPEG are supported.
