Bmp to png converter tool What is a bmp to png converter?
This tool transforms BMP (Bitmap) format images to PNG (Portable Network Graphics) format. BMP format does not support transparency but PNG does support transparency. As a result, in BMP pictures, transparent regions are often represented by a solid color, such as green, red, black or white. This tool allows you to replace all occurences of a certain color and related colors within a certain color similarity threshold range with completely transparent pixels. The Opacity Mask option allows you to easily see, which pixels will stay opaque, and which will become transparent. This option has no effect on the actual PNG image, it's only for visual inspection.
