Convert BMP to PNG
Turn huge old BMP files into compact PNGs.
BMP files are uncompressed and often enormous. Converting to PNG keeps the image lossless while making the file dramatically smaller.
Drop in your BMP files and download PNGs. Everything runs in your browser.
Frequently asked questions
Is PNG smaller than BMP?
Much smaller — PNG compresses losslessly, while BMP stores every pixel uncompressed.
Will I lose any quality?
No. PNG is lossless, so the image is identical, just smaller.
