How to convert PNG to BMP offline
Choose local PNG image files, choose "BMP" as the target image format, then click the "CONVERT OFFLINE" button to start offline conversions in bulk. File size can be up to 2GB.
This offline converter will first try to use the Canvas API in your web browser to convert images. The supported image formats depend on your current web browser. For example, the latest Chrome browser supports AVIF images while some older versions do not. The offline converter will then try to use JavaScript to convert the images if your current web browser doesn't support the image format. Use our online converter instead if this offline converter doesn't work in your web browser.

| Introduction | 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. | 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. |
