About BMP to PNG conversion
BMP (Bitmap) is an uncompressed raster format that stores every pixel without any compression, resulting in very large files. PNG (Portable Network Graphics) is a lossless raster format that compresses images without discarding any pixel data.
One practical reason to switch from BMP to PNG is to gain full transparency support. PNG preserves alpha channels, making it the right choice for logos, screenshots, illustrations, and anything that needs a transparent background. If you are not using transparency, the files will look identical in quality to the source.
