Convert BMP to PNG Online
BMP stores images pixel by pixel without compression, so the files are very large and many websites refuse them. Upload your BMP files, click "Convert" and download them as PNG. PNG is lossless and keeps transparency, so it is ideal for editing, screenshots, logos and graphics.
Transparent areas stay transparent in the PNG. The conversion runs in your browser, so your files are never uploaded.
