You can share annotated PDFs with other users through Google Drive, OneDrive, Google Classroom or your Learning Management Systems - just ensure that the user you are sharing with has OrbitNote installed as well, in order to see the annotations.

For sharing with users that don’t have OrbitNote, you can use the Download button and select the option to include your annotations. This will include all annotations, drawings, text, highlights, signatures and images in a new copy of the PDF.
