What is PNG

Learn about the Portable Network Graphics format.

By Hannah Williams

Portable Network Graphics (PNG) is a graphics file format that supports lossless data compression.

The PNG format was created as an improved, non-patented replacement for the most used lossless image compression format on the Internet, Graphics Interchange Format (GIF).

PNG was developed by an Internet committee, specifically with the intention to be patent-free. The format provides a number of improvements compared to the GIF format.

For example, PNG supports palette-based images, grayscale images and full-colour non-palette-based RGB images (with or without alpha channel).
