Guys I don’t have MS Project installed on my computer and I don’t want to purchase one right now. Can anyone tell me how can I view mpp file online free of cost? Also, do give me a short description of the site.
You can view .mpp files online for free with the help of following web applications/tools.
1) Gantter.com
 Gantter.com provides a free online project manager which works similar to MS Project. Guntter gives you the option to import .mpp files which mean that now the partner can visit gantter.com, import the .mpp file created by us and view it online for free. It’s all simple to do, just upload and view or edit the file.
If you are handy with MS Project, then Gantter will turn out to be an easy and productive tool for you.
2) Project.to
Project.to provides us with the options to upload, view and even share .mpp files online. It offers both free and paid services. You can delete files immediately after viewing them. Project.to allows us to save files on MS Project server licenses.
Other useful features of the project.to include change/version management, Collaboration, Email integration, Gantt charting, Milestone tracking, Project template integration, Progress reporting, Resource management, Scheduling and Workforce management. It is supported on almost all platforms.
If you have an MPP file and you want to open it without installing Microsoft Project, you can use a free online service called Free Online Project Viewer. It doesn’t require you to download anything. It allows you to easily open your Microsoft Project file right into your web browser without using any plug-ins or downloading a program.
The service can open MPP files created from Microsoft Project versions 2003, 2007, 2010, 2013, 2016, and earlier. But the only limitation is that you can only open files as big as 2 MB. If you need to open a much bigger file, you need to download their installable application either for PC or Mac with free 30-day trial period.
If you want to try their application, download their Project Viewer 365 for PC. It supports Windows XP, Windows 7, Windows 8.1, and Windows 10 both 32-bit and 64-bit. Microsoft Windows Vista is not officially supported. For Mac, download Project Viewer 365 for Mac. The MPP file format is an extension name used for a project file created by Microsoft Project.
