What is the Difference Between TIFF and PDF?
Readability
When it comes to the readability of PDF vs TIFF, PDFs are much easier to view than TIFFs and also allow for commenting within the PDF and printing from any device. TIFFs do not offer the same level of flexibility.
Security Features
Your PDF files can be password-protected and assigned specific viewing and printing access. If you decide later you would like to remove specific document access, you can easily do so with a PDF. With TIFF files, while you have the option of disallowing access to specific viewers, the security permissions are by far more limited than PDFs. And with TIFF files, once you share access with another user, it is very difficult to revoke that access.
Archiving
PDF was designed with archiving in mind, specifically long-term archiving. With PDF files, you can feel assured that the readability (and ability to view the documents) will be available for an infinite amount of years to come. Major publications and libraries utilize PDF files for this reason. TIFF file formatting is no longer as popular of a selection as PDF and therefore, fewer publications and businesses are choosing to archive in this format
