Can I directly convert .mpp files to .pdf format.
Directly converting Adobe Portable Documents to Microsoft Project Files (.pdf to .mpp conversion) is most likely not possible. To our knowledge, there is no way to convert a previously exported project (in .pdf format) back to a MS Project File (.mpp). PDF/XPS documents are mere snapshots of .mpp projects.
Several online file converters advertise their capability to execute .pdf to .mpp conversions, yet we highly doubt their quality and reliability.
