What is a BMP file?

BMP (Bitmap Image File) is an older, uncompressed image format that stores images pixel by pixel. It was widely used in early Windows systems and applications. BMP files retain all image details but are usually very large compared to modern formats.

The downside of BMP is its large file size and limited support for features like transparency and advanced compression.

What is a PNG file?

PNG (Portable Network Graphics) is a lossless image format that stores images without quality loss. It supports transparency (alpha channel) and is widely used for graphics, logos, icons, screenshots, and images with sharp edges or text.

PNG files are generally smaller than BMP files, provide better compatibility, and preserve full image quality.

Why convert BMP to PNG?

Converting BMP to PNG makes sense when:

PNG offers smaller files and lossless compression compared to BMP.
