This splits to a limit rather than at a place: every N pages, or into chunks under a maximum file size. The second is what you need when a portal or mail server rejects anything above a stated limit.
Parts are kept below the limit you set. Because pages vary, they will not be identical in size.
It cannot be split further. Compress PDF first.
For upload limits, yes, because size is what the limit measures.
These tools handle one document at a time. When the job is thousands of files, Greenbooks handles document digitization as a managed service, including bulk scanning, OCR and metadata capture, with the output loaded into DocuVenta DMS. Talk to us about volume work.
