File extension .png
Internet media type image/png
Description: The PNG (Portable Network Graphic) is a graphics file format used for adding transparencies to an image. PNG is often considered as a replacement for both JPEG and GIF formats and combines the features of both. PNGs enable you to have opaque and transparent components in one picture. Since they offer a better color flexibility, they're considered a great option for web designers.
Technical Details: A PNG file offers a higher quality level than a GIF file. PNG files support both the 24-bit RGB and 32-bit RGBA color profiles but do not support the CMYK profile, simply because they weren’t designed for printing. The reason you would choose this format over GIF is that PNGs don't have copyright limitations and lets you work with a wider range of colors.
