What is BMP to PNG Converter?

BMP (Bitmap) is an old uncompressed image format developed by Microsoft. It stores every pixel without compression, resulting in massive file sizes. A 5MB photo in PNG could be 50-100MB as a BMP file. BMP is rarely used today due to its inefficiency, but many older programs and scanners still output BMP files.

PNG (Portable Network Graphics) is a modern format that uses lossless compression to dramatically reduce file size while maintaining perfect quality. A BMP to PNG converter transforms large, uncompressed BMP files into efficient PNG format, reducing file size by 70-90% with zero quality loss. PNG also supports transparency, making it ideal for web graphics and logos.

Frequently Asked Questions

Why should I convert BMP to PNG?

BMP (Bitmap) files are uncompressed and extremely large. Converting BMP to PNG reduces file size significantly while maintaining perfect quality. PNG uses lossless compression, meaning you get smaller files without any quality loss. PNG also supports transparency, making it ideal for web graphics, logos, and images that need transparent backgrounds.

Will I lose quality when converting BMP to PNG?

No! PNG uses lossless compression, which means there is absolutely zero quality loss. Unlike JPG which discards some data to achieve smaller sizes, PNG preserves every pixel perfectly. You get the exact same visual quality as the original BMP, just with a much smaller file size thanks to efficient compression.

Is it safe to convert BMP files online?

Yes! Our converter is completely safe because everything happens in your browser. Your BMP files are never uploaded to any server - the conversion is done locally on your device.

What is the difference between BMP and PNG?

BMP (Bitmap) is an old uncompressed format that stores every pixel without any compression, resulting in enormous file sizes. PNG (Portable Network Graphics) uses smart lossless compression to achieve much smaller file sizes while maintaining perfect quality. PNG also supports transparency, which BMP doesn't handle well. PNG is the modern choice for graphics, screenshots, and images requiring perfect quality.

Can I convert multiple BMP files at once?
