What is PNG format and with which image edition program can I use it?
The PNG format (pronounced “PING”) is the most advanced image format, it utilizes lossless compression, meaning no image data is lost when saving or viewing the image. PNG is a universal format that is recognized by all the edition graphic programs (Adobe Photoshop®, Core Photo Paint®, Paint Shop Pro®, Unload Photo Impact®, MGI Photo Suite®, Microsoft Photo Editor®, Macromedia FreeHand®, etc.) nevertheless as work on the PNG format has been progressing recently since early 1995, previous versions to that date could not recognize this format. It is important to indicate that recent versions of programs so popular as Microsoft Word® and Microsoft Power Point® recognize images in PNG format even respecting the transparent background.
