BMP to PNG Converter
Convert a BMP picture into a PNG image. Set output dimensions, sharpening, brightness, contrast, saturation and JPEG/WebP quality where supported.
Why convert BMP to PNG?
Use PNG when your next application needs preserving sharp edges, screenshots and transparent graphics. BMP images often store large uncompressed pixel arrays, so converting them can reduce download or storage size.
The converter decodes the BMP image, applies your selected size or appearance adjustments, and writes PNG output. PNG stores lossless pixels and supports transparency, making it useful for icons, diagrams and screenshots.
Instructions
- 1
Choose a BMP file from your device.
- 2
Adjust output size and supported image settings, then convert to PNG.

Download the result and check the output.
About this tool
Convert a BMP picture into a PNG image. Set output dimensions, sharpening, brightness, contrast, saturation and JPEG/WebP quality where supported.
BMP decoding depends on browser support. JPG output replaces transparent areas with your selected background color. Check the result before deleting the original.
Practical questions
What changes between BMP and PNG?
The tool decodes a BMP image and encodes its pixels into a new PNG file. Changing the extension alone would not perform this conversion. The browser must successfully decode the source format before the export can run.
What should I check before using the result?
PNG preserves pixel detail losslessly and supports transparency, but the result may be larger than a compressed photographic format. This conversion cannot restore details already lost in the input.
