Merge PDFs

Page tools

  • Organize pages… shows every page as a thumbnail so you can reorder or delete them.
  • Split pages saves each page as its own PDF.
  • Rotate pages turns sideways scans upright.
  • For images, Combine into PDF makes one PDF out of several pictures.

PlanetOS does all of this on your computer. Your files are never uploaded, and it works without an internet connection.
