Convert BMP to PNG
Turn BMP images into lossless PNG images. Everything happens in your browser, so your images never leave your device.
Why convert BMP to PNG?
BMP files are usually uncompressed, so they're far larger than they need to be and awkward to share. PNG is lossless, supports transparency and opens everywhere, which makes it the safe format for editing, screenshots and graphics.
The background stays as it is
BMP has no transparency, so the PNG keeps the same solid background. PNG supports transparency, but a converter can't tell which pixels are "background". To get a transparent PNG, remove the background in an editor first.
Quality is preserved
BMP and PNG are both lossless, so every pixel carries over exactly. BMP is usually uncompressed, so the PNG will be much smaller with no loss at all.

Questions
Will converting BMP to PNG make the background transparent?
No. BMP has no transparency, so the PNG keeps the same solid background. Remove the background in an editor first if you need a transparent PNG.
Will converting BMP to PNG reduce quality?
No. Both formats are lossless, so every pixel is kept exactly.

No. The conversion runs in your browser, on your own device, so your images are never sent to a server. Once the page and converter have loaded, it keeps working even if your connection drops.
