PNG

Portable Network Graphics

PNG stands for Portable Network Graphics, and it is a popular raster graphics file format that supports lossless data compression. PNG was created as an improved, non-patented replacement for GIF, and is the most used lossless image compression format on the Internet. It supports a range of colors, including full-color and grayscale images, and also supports transparency, making it suitable for graphics, logos, and detailed artwork.

BMP3

Microsoft Windows bitmap image (V3)

BMP3 (Bitmap Image File V3) is an image file format developed by Microsoft, commonly used for storing two-dimensional digital images in a wide range of color depths. While BMP files are capable of storing detailed images without any compression—preserving the original quality—they often result in large file sizes, making them less ideal for web usage or sharing.
