PDF stands for Portable Document Format. It's a versatile file format created by Adobe that gives people an easy, reliable way to present and exchange documents
Tag Image File Format, abbreviated TIFF or TIF, is an image file format for storing raster graphics images, popular among graphic artists.
To convert a pdf document to a bunch of TIFF images, you need to install third-party software on your computer to make the conversion in the past. Now many online websites such as this can help you with that which requires you upload your pdf file to the cloud, which is relatively much convenient. However if you document contains private data you do not want others to know, this might be of some trouble.

Without the internet connection, nobody will be able to intercept or steal your data.
