How to convert BMP to PNG offline

Choose local BMP image files, choose "PNG" as target image format, then click the "CONVERT OFFLINE" button to start offline conversions in bulk. Each file can be up to 2GB.

This offline converter will try to use canvas in web browser to convert images first. The image format depends on whether your current web browser supports. For example: the latest Chrome browser supports AVIF images while some old versions don't. Then the offline converter will try to use JavaScript to convert images if your current web browser doesn't support the image format. Use online converter instead if this offline converter doesn't work in your web browser.

Introduction The BMP file format, also known as bitmap image file or device independent bitmap (DIB) file format or simply a bitmap, is a raster graphics image file format used to store bitmap digital images, independently of the display device, especially on Microsoft Windows and OS/2 operating systems. Portable Network Graphics (PNG) is a raster graphics file format that supports lossless data compression. PNG was created as an improved, non-patented replacement for Graphics Interchange Format (GIF), and is the most used lossless image compression format on the Internet. PNG itself does not support animation at all. MNG is an extension to PNG that does; it was designed by members of the PNG Group.
