How to Convert BMP to PNG: 5 Different Ways to Make Your Choice

You’ll need to convert BMP files to PNG to optimize file size and take advantage of other PNG format benefits in many situations. If you’re wondering how to convert BMP to PNG, this article provides a comprehensive guide with five distinct methods, ranging from easy-to-use online tools and specialized image editing software to command-line and Python code solutions for developers.

What is a BMP File?

Bitmap files, or BMPs, are popular image files, especially associated with Windows. This format stores images as pixels and can support both color and black-and-white images, from the simplest (black and white only) to complex, colorful images.

Though BMP files may lack the flexibility of formats like JPEG or PNG, they remain widely used due to their simplicity and compatibility with Windows. However, BMP files do not compress images, often resulting in large file sizes, which can make storage and sharing cumbersome.

BMP files are commonly used where maximum image quality is required, such as in print or graphic design, where pixel-level accuracy is important.

Key Features of BMP:

• High quality
• Large file size
• High compatibility

What is a PNG File?

PNG (Portable Network Graphics) is a lossless compressed image format, meaning it can compress images to smaller file sizes without compromising quality. Developed as a modern alternative to GIF, PNG files remove the limitations of color and quality that affect GIF files.

PNG files are especially useful for storing graphic images, logos, or any images requiring transparent backgrounds without a loss in quality during compression. Additionally, PNGs are ideal for web usage, thanks to their lossless compression and clarity.

Key Features of PNG:

• Lossless compression
• Transparency support
• High compatibility
