What is an MPH file?
An .MPH file usually contains a multiphysics simulation model or a multimedia slideshow project. The most common type is the COMSOL Multiphysics simulation model. These files store complex physics simulations and often use a compressed .ZIP or Java-based internal structure. Another type is the Photostory Deluxe Project created by MAGIX. These project files save slideshow settings, transitions, and media references using a RIFF-based file format.
How to open MPH files?
Because the .MPH extension has multiple possible meanings, viewer.online/mph analyzes .MPH files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. If you know the origin of the file, you can open simulation models using COMSOL Multiphysics. For slideshow projects, you need MAGIX Photostory.
Best practices and troubleshooting
If you try to open an .MPH file and it fails, you likely have the wrong software for your specific file type. Do not change the file extension, as this will not change the actual file format. We recommend file conversion to sensible target formats on convert.guru. For example, you can convert a slideshow project into a standard .MP4 video or export simulation data to .CSV.
Software and tools
To edit and manage these files locally, you must install the official software. COMSOL Multiphysics is required for engineering models. MAGIX Photostory Deluxe is required for photo slideshows.
Summary
viewer.online/mph directly opens and previews .MPH files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
