Convert BMP to PNG — Free Online Converter, No Upload

Compress huge BMP files into small lossless PNGs — same quality, 90% smaller. The conversion runs entirely in your browser using JavaScript and the Canvas API — your file never leaves your device, no signup required, no watermarks added.

Why convert BMP to PNG?

BMP files are uncompressed and enormous — often 10–20× larger than the equivalent PNG. PNG provides identical lossless quality with dramatically smaller file sizes, making it the right modern replacement for BMP in nearly every scenario.

Common use cases

• Shrink huge BMP archives
• Make BMPs web-friendly
• Save disk space without quality loss
• Modernize legacy graphics libraries

How to convert BMP to PNG

1. Drag your .bmp file into the converter, or click to browse.
2. Press the Convert to PNG button — your browser does all the work locally.
3. Download the resulting .png file. Your original file was never uploaded anywhere.
