Hi, Sean_3
I am Akiva independent advisor
When you insert an object into a PowerPoint slide, PowerPoint creates a graphic link to the object. You can double click on the link during the presentation to see the object in its native program. HTML files are objects supported in PowerPoint, so you can use the "Insert object" function to link to a web page document on your hard drive.
Step 1
Run Microsoft PowerPoint and open the presentation to which you want to add the HTML object.
Step 2
Browse to the slide you want and click on the location where you want to place the object.
Step 3
Click on the "Insert" tab on the ribbon and click on the "object" icon.
Step 4
Click "Create from file," then "Browse," and search for the HTML file on your hard drive. Click "OK" when you have selected the desired HTML file.
Step 5
Check the "Link" box if you do not want the file to be embedded in the PowerPoint document. If you do not check this box, the current version of the HTML file will be saved as part of the PPTX document. You should not check this box if you are going to show the presentation on another computer.
Step 6
Mark the "Show as icon" checkbox if you want the slide to display an HTML icon. If you don't check this box, an image of the HTML file will be seen in your presentation.
Step 7
Click "Accept" to insert the HTML object into your presentation.
Step 8
Click on the HTML object icon or thumbnail preview, and then click and drag the anchors at the edges of the image to resize it to your liking.
I hope it helps
