Converter: turn HTML into editable PowerPoint

Download Starting HTML above for a safe first conversion, or use your own HTML deck. Keep this source file. Open the converter and choose or drop the file; you can also paste the complete HTML.

Check: The preview shows all four Harbourline slides, or all slides from your own deck.

Review every slide, including long headings, images and charts. Read any warnings before converting. A self-contained file such as the practice deck works offline once the tools are prepared; decks with external assets may need a connection to load those assets first.

Check: The preview is complete and you understand any reported limitations.

Choose Convert to PPTX (Create PowerPoint in the editor’s export panel), wait for completion and save the PowerPoint. Open it in your presentation app. Select a heading to check editable text; the practice deck’s chart also carries editable data. Some visual effects may be preserved as images.

Check: The saved PowerPoint opens, has the expected slides and lets you edit the practice heading and chart.

Store the HTML and PowerPoint together with matching names, such as harbourline-v1.html and harbourline-v1.pptx. Keep a new pair after later revisions. If the PowerPoint becomes your latest version, import that file before starting a new HTML-based revision.

Check: You can identify which source goes with the PowerPoint and open both independently.
