TIFF or PDF for my document imaging project?

Ah, the age-old argument…what file format do I use for scanning and archiving? TIFF, PDF, JPG, MDI, BMP? I will focus on the two most prevalent options, TIFF and PDF.

TIFF – TIFF stands for Tagged Image File Format and has become the industry standard for Document Imaging. All of the scanner vendors, Document Management Software and Enterprise Content Management vendors support this format. TIFF was originally developed by the company Aldus as a standard for imaging. Adobe has since acquired Aldus. The TIFF format provides compression to produce manageable image sizes.

PDF – PDF stands for Portable Document Format, and was created by Adobe for simple document exchange. It has quickly been adopted by the document imaging industry because of the proliferation of the Adobe Reader. There are 3 types of PDFs: Image, Text and Image+Hidden Text. The Image + Hidden Text gives you an all in one package if you want a searchable file. The newest PDF standard is the PDF / A, or PDF Archive standard. This PDF type will insure long term archival compatibility. It also sets a standard for an all-in-one package that includes metadata, OCR text and the image itself.

So which do you choose?? I cannot tell you how often I get this question from customers. My answer is usually in the form of a question: What are you going to do with the documents once they are archived? If you distribute them outside the organization, then PDF is usually the best choice, as Adobe Reader is on over 90% of the PCs nowadays, and you will not have to deal with someone trying to open a TIFF. If your documents are going to be used for internal reference, and will be viewed through a document management system, then TIFF is perfectly fine. Another consideration will be OCR text. Does your document management system work with TIFF and PDF??

Most software today will accommodate either image format; just make sure it will meet all your needs. You can find a wide variety of software solutions at Scanning and Imaging Solutions.
