Device-Independent Bitmap (DIB) is a type of bitmap (BMP) that displays properly on any device. DIB accomplishes this through the use of a color table that translates pixels to RGB colors. There are two types of DIB, bottom-up and top-down. The main difference between the two is that bottom-up DIB cannot be compressed, while top-down can. For additional information, Microsoft published an excellent article that describes the more technical aspects of DIB.

As a device-independent file type, DIB opens in most image viewers across platforms. For example, on Microsoft Windows, it opens in Paint. On macOS, it opens in Apple Preview, Apple Photos, and ColorStrokes. DIB opens readily in all Adobe image-viewing and editing applications. Furthermore, on Linux/Unix, as well as all platforms, you can use XnView MP and the free program GIMP to open DIB files.


DIB files convert easily to many other common file formats, such as PNG, PDF, JPG, and TIF. To accomplish this, there are lots of free image converter programs to choose from, such as XNConvert.

Alternative programs such as GIMP or Adobe Photoshop are useful for opening and editing PNG files. PNG files are a bit larger than other file types, so exercise caution when adding them to a web page.
