Convert BMP to PNG
Turn BMP images into PNG right in your browser. Lossless images with transparency. Nothing is uploaded, and many images convert at once.
Why convert BMP to PNG?
- PNG keeps every pixel exactly as it is, with no further quality loss.
- PNG supports transparency, so logos and cut-outs keep clean edges.
- BMP files are uncompressed, so they take far more space than they need to.
Good to know
- PNG is lossless, but it cannot bring back detail that a lossy BMP file already lost, and the file is often larger.
- Photo orientation is respected and location (GPS) and camera data is not copied into the converted file.
Questions about BMP to PNG
Will converting BMP to PNG reduce quality?
Converting to PNG adds no further loss, because PNG is lossless. It cannot restore detail that BMP already discarded, though.
Can I make the PNG files smaller or change their size?
Yes. Use the quality setting, or fit the images to a maximum width, or scale them by a percentage. The results update straight away.
Are my images uploaded to a server?
No. Everything happens inside your browser, on your own device. Your images are never sent anywhere, which also means it keeps working on a slow connection once the page has loaded.
Is it really free? Do I need an account?
Yes, it is free and there is no account, watermark or daily limit.
How many images can I convert at once?
Up to 200 at a time. Drop a whole folder, convert them together, and download everything as one ZIP file.
