Turn a huge uncompressed BMP image into a crisp PNG file that opens anywhere, right in your browser.
Only BMP images are accepted on this page.
Your image never leaves your browser. Conversion happens on your own device, and nothing is uploaded to a server. PNG is lossless and compressed, so the converted file is usually far smaller than the BMP with no pixel changed. Transparency in the BMP is kept in the PNG.
BMP is the classic Windows bitmap format, and it stores images with almost no compression, so files are huge for no visible benefit. PNG keeps every pixel exactly like BMP, but with real compression and support on every device. The BMP to PNG Converter turns your BMP into a PNG without sending it anywhere.
Everything runs in your browser, so your images are never uploaded to a server. Choose a BMP file, convert it, and download the PNG straight to your device.
Keep the BMP only when a specific Windows program demands it. For everything else, PNG is better in every way: smaller files, the same perfect pixels, transparency support, and universal support. Converting BMP to PNG is one of the few conversions with no downside at all, because nothing is lost and the file gets smaller. If you need the smallest possible file for sharing a photo, convert to JPG instead and accept a little quality loss.

No. Both BMP and PNG are lossless, so converting from BMP to PNG keeps every pixel exactly as it is in the BMP. The conversion itself adds no loss at all.
BMP stores pixels with almost no compression, while PNG compresses the same pixels losslessly. The picture is identical, but the PNG file is usually far smaller, which makes it faster to share and store.
Yes, when the BMP carries an alpha channel. BMP files with transparency keep their transparent and partly transparent pixels exactly in the converted PNG.
The tool shows a clear message and does not convert anything. Choose a BMP image and try again.
No. The conversion happens in your browser on your own device, so your images never leave your computer.
