Why Use PNG for TIFF Conversions?
PNG (Portable Network Graphics) is the ideal successor to TIFF for web use. While TIFF is the standard for high-end photography and scanning, PNG allows those same images to be displayed in browsers without losing quality.
Unlike JPG, which "throws away" data to make files smaller, PNG uses Lossless Compression. This means when you convert a TIFF to PNG, the result is an identical pixel-for-pixel copy of the original source.
