Many devices cannot natively open MPP or Visio diagrams, and installing heavy desktop software is not always possible or necessary.
DoconutApp solves this by offering a free, browser-based viewer that instantly renders:

  • Microsoft Project files: MPP
  • Visio diagram files: VSD, VSDX, VSDM

Just upload your file, wait a few seconds, and view it right from your browser—no setup, no add-ons, and no local installation.
