This tool converts PowerPoint presentations and audio files to HTML5 and video as usual, so you do not need PowerPoint presentation to be in .PPTX format. Using PowerPoint to HTML5 Tutorial By G. Michael Schatz I have a number of projects that involve converting PowerPoint files to HTML5. I'm sure most people doing such conversions have found a way to accomplish the required task. However, how can you be sure you don't hit a roadblock that would make this process impossible to complete at all? You should be aware of various issues that may prevent you from accomplishing the task, and what you can do to prevent those issues from occurring. You should also know that, based on the information and experience you have gained at different web events, you can easily apply the knowledge to do any of these conversion tasks, especially when dealing with documents delivered by PowerPoint. The following is a brief compilation of the most common issues you encounter. · Using PowerPoint 2023 or 2016 1. The first thing I noticed while starting out with HTML5 is that PowerPoint will always open in landscape mode. I'm glad that Microsoft switched to a view called Smart Cover. This will not only save a bit of space on screens, but it also allows you to resize the image of your PowerPoint presentation, which is an even better feature than what PowerPoint has already. · You can't adjust the margins or borders of your PowerPoint presentation. This is because your PowerPoint slides are delivered as two separate files, separated into an Office file and an HTML document. If you want to use margins, you must convert your PowerPoint to a template. · The PowerPoint presentation is formatted as a single document. This is different from what we're used to, which typically means that the slides will be spread across multiple pages on the web. This is also a disadvantage compared with the previous method of PowerPoint to HTML5 conversion, where you can use multiple web pages for each slide. · When exporting your Microsoft PowerPoint documents, you cannot select images from the slide-show or audio files. Since images and audio files are delivered as separate files, you must convert PowerPoint to either template or web page. · When trying to open PowerPoint from Adobe Flash, HTML or PowerPoint 2010, you receive an unsupported browser error. I'm using an iPhone, but this is still a very annoying issue. · When trying to view the slide-show presentation, there is a small amount of white space between the slide and the background.
