Portable Network Graphics (PNG) is a raster-graphics file-format that supports lossless data compression. 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 alpha channel for transparency), and full-color non-palette-based RGB images (with or without alpha channel).

The BMP file format, also known as bitmap image file or device independent bitmap (DIB) file format or simply a bitmap, is a raster graphics image file format used to store bitmap digital images, independently of the display device (such as a graphics adapter), especially on Microsoft Windows and OS/2 operating systems.

Note: Using BMP 32bit is discouraged due to lack of proper support across browsers, so image will be 24bit (no alpha channel)

The Graphics Interchange Format (GIF)

Palette based image with support of animation (not implemented), Transparency (totally transparent color - use 0x00)
