PNG was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF). PNG supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images (with or without an alpha channel for transparency), and full-color non-palette-based RGB or RGBA images.
What PNG means?
PNG stands for “
Portable Graphics Format
”. It is the most frequently used uncompressed raster image format on the internet. This lossless data compression format was created to replace the Graphics Interchange Format (GIF). … Like GIF images, PNG also have the ability to display transparent backgrounds.

Is PNG progressive?
Indexed-color, grayscale, and truecolor images are supported, plus an optional alpha channel. Sample depths range from 1 to 16 bits. PNG is designed to work well in online viewing applications, such as the World Wide Web, so it is fully streamable with
a progressive display option
.
Can a PNG be 16 bit?
As with RGB and gray+alpha,
PNG supports 8 and 16 bits per sample for RGBA
or 32 and 64 bits per pixel, respectively. Pixels are always stored in RGBA order, and the alpha channel is not premultiplied.
What is PNG commonly used for?
PNG (
Portable Network Graphic
)
The Portable Network Graphic (PNG) file format is ideal for digital art (flat images, logos, icons, etc.), and uses 24-bit color as a foundation. The ability to use a transparency channel increases the versatility of this file type.
