Free MPP viewer
Open an MPP file online, without Microsoft Project
Got an .mpp file and no Microsoft Project? Drop it here: within seconds you see the plan as a Gantt chart, with tasks, dates, dependencies and resources. No sign-up, no software to install.
Up to 10 MB. The file is not stored.
How to open an .mpp file in three steps
Upload the file
Drag the .mpp file into the box above or choose it from your computer. .mpt templates, .mpx files and Microsoft Project XML work too.
View the plan
A read-only Gantt chart opens: WBS structure, durations, start and finish dates, dependencies, milestones and progress. Switch to the list to read the tasks row by row.
Edit it if you need to
With a free account the file becomes a Planitude project: update it, recalculate the dates and share it with your team, without licenses.
What is an MPP file?
MPP is the format Microsoft Project uses to save project plans. It holds the tasks and their structure, durations, dependencies, working calendars, resources with their assignments, baselines and progress. It is a proprietary binary format: without Project you can’t open it in Excel or a text editor.
The format has changed across versions: Project 2000–2003, Project 2007 and Project 2010 and later (including Project for Microsoft 365) each save a different variant. The viewer reads all of them; it can’t open password-protected files.
What you see in your file
WBS structure
Phases and subtasks at every level, with the WBS code of each row.
Dates and durations
Start, finish and duration of each task, read from the file and shown in your time zone.
Dependencies
Finish-to-start, start-to-start, finish-to-finish and start-to-finish links, with leads and lags.
Milestones
Key dates, drawn as diamonds on the timeline.
Progress
The percent complete of each task, on the bar and in the list.
Resources
The people and materials assigned, next to each task.
Your file stays yours
The file is processed in memory on servers in the European Union, in Germany, only for as long as it takes to draw the Gantt chart. We do not save it, archive it or use it for anything else.
If you choose to edit it, the file stays in your browser until you create an account and confirm the import: only then does it become a project, visible only to you and the people you invite.
Other ways to open an MPP file
The viewer is the fastest way to look at a plan. If you need something else, these are the usual alternatives.
Microsoft Project desktop
Opens and edits .mpp files natively, but needs a license for each person: by subscription with Planner and Project Plan 3 or 5, or Project Standard or Professional.
Planner premium
Microsoft’s offer after Project Online: plans live in the Microsoft 365 cloud and advanced features such as dependencies and baselines need a premium license per person.
Export to XML or PDF
Whoever sends you the file can save it as Microsoft Project XML or print it to PDF. A PDF opens anywhere, but it doesn’t update.
Planitude
Opens the file in your browser and, with a free account, lets you edit it, share it and export it back to Microsoft Project XML.
MPP file questions
Can I open an .mpp file without Microsoft Project?
Yes. Drop the file on this page: you see it as a Gantt chart and as a task list, free and without installing anything.
Do I need to sign up?
No, you don’t need an account to view the file. A free account is only needed if you want to edit the plan and save it.
Which versions of Microsoft Project are supported?
.mpp files from Project 2000 onwards, up to the current versions of Project for Microsoft 365, plus .mpt templates, .mpx files and Microsoft Project XML.
Is my file stored?
No. It is read in memory to draw the Gantt chart and then discarded. It is only saved if you create an account and confirm the import.
Why won’t my file open?
The usual causes are password protection, a damaged file or a file over 10 MB. In those cases try saving it as Microsoft Project XML from Project, or create an account: the import accepts up to 25 MB.
Can I edit the file and send it back in Project format?
Yes. With a free account you edit the plan in Planitude and export it to Microsoft Project XML, which Project opens and can save as .mpp again.
