When to Use PNG. Use PNG when you need smaller file sizes with no loss in quality. PNG files are usually smaller than TIFFs, in my experience. PNG also supports alpha transparency (soft edges) and was developed to be a Web graphics replacement for GIF. Note that if you want to retain full transparency, you will need to save your PNG file as PNG-24 and not PNG-8. PNG-8 is useful for reducing the file size of PNG files when you don't need transparency, but it has the same color palette limitations as GIF files.
png files nearly always use file extension png or png and are assigned mime media type image png png was approved for this use by the internet engineering steering group on 14 october 1996 and was published as an iso iec standard in 2004
