File format information for RGB and PNG

Extension	RGB
Full Name	Raw red, green, and blue
Type	Image
Mime Type	application/octet-stream
Format	Binary

RGB files are a type of image file where the image data consists of a stream of raw pixel data with no header information. This lack of header information, which usually contains the image dimensions among other properties, means the image size must be input prior to loading an RGB image in order for it to be displayed correctly.

Within an RGB file, image data is stored as a sequence of uncompressed red, green, and blue values used to represent each pixel. Each color channel is 8 bits in size, creating a total of 24 bits across the RGB color range, or roughly 16.7 million colors.

RGB files are a legacy file format that can be opened with certain image editing applications that still support this format; alternatively, we have a set of RGB image conversion tools designed to convert RGB files to other, more modern formats, such as PNG.

Extension	PNG
Full Name	Portable Network Graphics
Type	Image
Mime Type	image/png
Format	Binary
Opens With	Paint.Net, Photoshop

PNG files are a widely used graphics file format used in areas where high-quality images (often with transparency) are required while also retaining a small file size. They are one of the most common formats of file used for web and print mediums and are particularly useful for logos, icons, and other images where multi-level transparency is desired.

The format itself was created in the 1990's with the main aim of storing computer graphics in a high-quality format while minimizing the required storage space. The longer-term aim was to displace the GIF file format and make PNG the number one format for non-lossy, high-quality image formats on the then-burgeoning world wide web.

One of the selling points of the PNG format is its support for multiple levels of transparency, making it superior to the GIF format, which can only handle a single level of transparency. Also, like GIFs, the PNG format supports palletizing image colors down to 256 or 16 colors to help reduce the file size of the PNG.
