BMP vs PNG Format Comparison

Aspect	BMP (Source Format)	PNG (Target Format)
Format Overview	BMP Bitmap Image File Uncompressed raster image format developed by Microsoft; stores raw pixel data directly without loss. Standard	PNG Portable Network Graphics Lossless image format supporting transparency, gamma correction, and high-quality graphics. Standard
Compression	No compression; stores full image data.	Lossless DEFLATE compression; reduces file size without quality loss.
Color Depth	1 to 24 bits per pixel depending on BMP variant.	8 or 16 bits per channel; supports true color and alpha transparency.
File Size	Very large; uncompressed data size proportional to resolution and bit depth.	Moderate; size varies by image complexity and transparency use.
Advantages	Simple format structure No loss of data fidelity Wide legacy support	Lossless compression Supports alpha transparency Ideal for web graphics and icons
Disadvantages	Extremely large file sizes Inefficient for storage and transfer No transparency or metadata support	File size larger than JPG for photographs No native animation support Less efficient for photographic images than JPG
Use Cases	Legacy Windows applications Basic graphics and icons Software and system testing	Web graphics requiring transparency Logos and UI elements Archival of high-fidelity images
Tooling & Ecosystem	Microsoft Paint Generic image processing libraries Windows viewers and editors	Adobe Photoshop, GIMP Browser-based editors and viewers ImageMagick, libpng

Why Convert BMP to PNG?

BMP files are uncompressed, resulting in very large sizes that are impractical for web use or sharing. Converting BMP to PNG leverages lossless DEFLATE compression to significantly reduce file size while preserving image quality and supporting features like transparency and gamma correction.

PNG’s wide adoption across web and design tools means your images will display consistently on all devices. Additionally, PNG supports alpha channels, making it perfect for overlays and graphics that require transparent backgrounds. By converting BMP to PNG, you streamline storage, speed up page load times, and maintain full image fidelity.
