TIFF format will be smaller for directly scanned documents. But the majority of
newly created documents originate in electronic form where a PDF can create a
smaller file than either the original file format of scanning a printout. We are
starting to convert our financial reports to PDF instead of printing them out. A
few examples: A 7,000 page report from our finance system was over 10,000k in ASCII
format but distilled to 9,000k as a PDF or about 1.3k per page versus 50k per page
for TIFFs. This was created in less than 30 minutes, and can be deployed within
minutes institution wide through our EDMS many times faster than just printing out
one copy. A 116 page Excel spreadsheet was a 737K Excel file and converted to a
452K PDF compared to about 5800K as TIFF scans. Another factor to consider is that
PDFs created from original documents far exceed the 200 to 300 dpi of normal TIFF
scans.
