In the further part of this page we have added a list of programs that should open your PPTMHTML file. It is enough you choose a proper application for your operating system, download and install it.


Files ending in PPTMHTML are MIME HTML files created by earlier versions of the Microsoft PowerPoint presentation software. Among other things, these files contain HTML source code similar to an html file. The source code is created in such a way that the browser displays a ppt document as similar as Powerpoint. Pptmhtml files can also contain other resources like pictures.

The PPTMHTML format is no longer supported by Microsoft. Documents that should be published on the Web should therefore be saved as an mhtml or mht file.

Newer versions of Microsoft Excel save HTML code as an html file.

How to open a PPTMHTML file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the PPTMHTML file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a PPTMHTML file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support PPTMHTML files. At this point we are looking for disk space where the application was installed in and we can link it with a PPTMHTML file. Since then, our operating system will use the selected program to support all PPTMHTML files.

Other issues

Despite the described problem with PPTMHTML there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the PPTMHTML file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the PPTMHTML file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
