Export to HTML5

Info

In Aspose.Slides 21.9, we implemented support for HTML5 export. However, if you prefer to export your PowerPoint to HTML using WebExtensions, see this article instead.

The export to HTML5 process here allows you to convert PowerPoint to HTML without web extensions or dependencies. This way, using your own templates, you can apply very flexible options that define the export process and the resulting HTML, CSS, JavaScript, and animation attributes.

Export PowerPoint to HTML5

This python code shows how you to export a presentation to HTML5 without web extensions and dependencies:

import aspose.slides as slides

with slides.Presentation("pres.pptx") as presentation:
    presentation.save("index.html", slides.export.SaveFormat.HTML5)

In this case, you get clean HTML.

You may want to specify the settings for shape animations and slide transitions this way:

import aspose.slides as slides

with slides.Presentation("pres.pptx") as presentation:
    options = slides.export.Html5Options()
    options.animate_shapes = False
    options.animate_transitions = False

    presentation.save("index.html", slides.export.SaveFormat.HTML5, options)

Export PowerPoint to HTML

This python code demonstrates the standard PowerPoint to HTML process:

import aspose.slides as slides

with slides.Presentation("pres.pptx") as presentation:
    presentation.save("index.html", slides.export.SaveFormat.HTML)

In this case, the presentation content is rendered through SVG in a form like this:

<body>
<div class="slide" name="slide" id="slideslideIface1">
     <svg version="1.1">
         <g> THE SLIDE CONTENT GOES HERE </g>
     </svg>
</div>
</body>

Note

When you use this method to export PowerPoint to HTML, due to the SVG rendering, you will not be able to apply styles or animate specific elements.

Export PowerPoint to HTML5 Slide View

Aspose.Slides allows you to convert a PowerPoint presentation to an HTML5 document in which the slides are presented in a slide view mode. In this case, when you open the resulting HTML5 file in a browser, you see the presentation in slide view mode on a web page.

This Python code demonstrates the PowerPoint to HTML5 Slide View export process:

import aspose.slides as slides

with slides.Presentation("pres.pptx") as pres:
    # Export a presentation containing slides transitions, animations, and shapes animations to HTML5
    options = slides.export.Html5Options()
    options.animate_shapes = True
    options.animate_transitions = True

    # Save presentation
    pres.save("HTML5-slide-view.html", slides.export.SaveFormat.HTML5, options)

Convert a Presentation to an HTML5 Document with Comments

Comments in PowerPoint are a tool that allows users to leave notes or feedback on presentation slides. They are especially useful in collaborative projects, where multiple people can add their suggestions or remarks to specific slide elements without altering the main content. Each comment shows the author’s name, making it easy to track who left the remark.

Let’s say we have the following PowerPoint presentation saved in the “sample.pptx” file.

Two comments on the presentation slide

When you convert a PowerPoint presentation to an HTML5 document, you can easily specify whether to include comments from the presentation in the output document. To do this, you need to specify the display parameters for comments in the notes_comments_layouting property of the Html5Options class.

The following code example converts a presentation to an HTML5 document with comments displayed to the right of the slides.

html5_options = Html5Options()
html5_options.notes_comments_layouting.comments_position = CommentsPositions.RIGHT

with Presentation("sample.pptx") as presentation:
    presentation.save("output.html", SaveFormat.HTML5, html5_options)

The “output.html” document is shown in the image below.
