Convert BMP to PNG Online
Reduce your Bitmap file size using PNG lossless compression. The output image is pixel-identical to the original, but significantly smaller.
Why Convert BMP to PNG?
BMP stores raw pixel data without compression, resulting in large files. PNG uses lossless compression (DEFLATE algorithm) to reduce file size by 50-80% without losing any image data.
PNG supports transparency (alpha channel), which BMP does not. If you need a smaller file that works on the web and preserves exact colors, PNG is the correct choice.

Frequently Asked Questions
Does BMP to PNG conversion lose quality?
No. PNG uses lossless compression. Every pixel in the output is identical to the input. There is zero quality loss.
How much smaller will my PNG file be?
Typically 50-80% smaller than BMP. The exact reduction depends on the image content. Images with large solid color areas compress more.
Can I convert BMP with transparency to PNG?
Standard BMP files do not support transparency. The converter will create a PNG with an opaque background. If your source has transparency data (32-bit BMP), it will be preserved.
Is converting BMP to PNG free?
Yes, our tool is 100% free to use.
