All PDF files must be 30 MB or less.  If your PDF file is larger than 30 MB,  you will need to split it into two or more files so that each individual file is 30 MB or less in size.

If your file is less than 800 pages and is over 30 MB,  it is likely you are scanning your file in either color or grey scale, or a high dpi (dots per inch).  Either of these options will create an unusually large file size.  We suggest that your scanner be set to 300 dpi or less, and set to black/white scan only.  You should only scan in color when it is appropriate and necessary for the document.
