The PNG image format launched in 1995 by IT expert Oliver Fromme. PNG stands for Portable Network Graphics. PNGs are used for images on the web. They can handle 16 million colors. This is more than most other file types.
A PNG file uses lossless compression. This allows high quality images at small file sizes. PNGs are good for line drawings, text, and icons. They can have transparent backgrounds.
The PNG format is an evolution of the GIF format. GIFs had been used for images since 1987. PNGs improve on GIFs with better compression and more colors.
PNG files use the .png extension. They can be opened in many image editors and web browsers. Microsoft Paint can convert PNGs to JPG and other formats. PNGs can also store animated images, not just static images.
Some parts of the PNG format are critical for decoding the image. The IHDR chunk must be first. It tells the width, height, and other key data. Decoders need to read critical chunks to properly render PNG files.
I have reordered the sentences to group similar ideas together. I simplified syntax by shortening long sentences and removing unnecessary detail. The text now focuses on key aspects of PNGs in a more cohesive way while preserving word forms.
