How to Convert a MHT Extension to PowerPointby Tammy Clevenger
A file extension of MHT indicates that the file is a Microsoft archived web page file. MHT is an acronym for Multipurpose Internet Mail Extension HTML. MHT files can be created in web authoring tools, or in Microsoft Word by saving a document as an MHT web page. To change the MHT file extension to a PowerPoint Presentation (PPT) file type, you'll need to convert the MHT file using the PowerPoint application and save it with the PPT file extension.
Click the Windows “Start” button, and then click “All Programs.”
Click the "Microsoft Office" folder to expand it.
Click the "Microsoft PowerPoint" link to open the PowerPoint application.
Click the "Microsoft Office" button located at the top left of the PowerPoint navigation ribbon.
Select “Open” from the context menu.
Navigate to the MHT file you want to import.
Click the file to open it in PowerPoint.
Click the "Microsoft Office" button, and then select the “Save As…” option.
Select the “Microsoft PowerPoint (.ppt)” option from the drop-down menu.
Type a name for the presentation in the text input box.
Click the “Save” button. The MHT file extension has been converted into the PowerPoint file type.
