The Portable Network Graphics (PNG) extension belongs to the raster family and performs lossless compression of the image. It has been designed as an improvement over the Graphics Interchange Format (GIF file) and is non-patented.

A PNG file can contain RGB or RGBA types of images. They can be either based on a palette or the full-color opposite, plus the standard grayscale images or the ones with an alpha channel that adds transparency. Since PNG has been designed simply to transfer images through the Internet and did not consider any professional printing tasks, the format doesn’t support other color types like CMYK. The image contained in the file is broken up to chunks, with such data as pixels or textual comments encoded and the integrity checking carried out in RFC 2083.

PNG File: FAQ

  • Is JPEG or PNG better?

The answer depends on the goal you’re trying to achieve. The main distinction between the two is that JPEG lowers the image quality and works better for reducing photos to sizes smaller than BMP. PNG, instead, somewhat compresses the file but preserves the quality, which is great for storing items like line drawings, text and iconic graphics.

  • What is a PNG file used for?

Such files contain a bitmap with the colors indexed and that enables to compress the image information without losses. A GIF file would do the same but it is limited by copyright. The former is a common choice for websites due to this.

  • Is PNG good for printing?

The PNG file definition implies that it is best used for screens. It can handle deep colors, which opens the possibility of working with photos in high resolution. But those tend to become very heavy due to the format being lossless. You can definitely print such a file, but the task is easier to perform with something more optimized, like a JPEG or TIFF.

  • Does PNG have a transparent background?

If the image you have is on a colored background, you will need to remove it first. Then the result could be saved in the PNG format which has been designed for Internet use. A slightly more common JPEG would not be able to keep the background transparent.
