TIFF is the format in which tagged images are saved. Moreover, they can be both vector and raster. The most widely used for packaging scanned images in related applications and in the printing industry. Currently, Adobe Systems owns the rights to this format. TIFF and TIF are the same format. TIF and TIFF files have the same structure, the only difference is in the extension. The format was born in 1986 thanks to the joint efforts of Microsoft and Aldus Corporation.
The Portable Document Format (PDF) is a versatile file format that preserves the fonts, images, and layout of the original document, regardless of which of many platforms and which of many applications the document was created on. It was initiated by Adobe and was originally intended for electronic presentation of printed materials. PDFs look the same no matter what device they are viewed on. Whether you're using Windows 10, Mac, Chrome OS, Android, Windows Phone, iPad, or Windows XP - on any software or hardware, PDFs remain the same.
