InterLeaved BitMap (ILBM) file format is a type of Raster graphics image file developed by Electronic Arts in the mid-1980s. An ILBM file is typically associated with Deluxe Paint - a graphic editing tool, but it is also used in various other applications, especially in ones that render images in video games. source

Opening IBLM Files

There are several ways to open and view ILBM files:

Using Deluxe Paint

Deluxe Paint, the software which the ILBM file format was originally created for, can naturally open this file type. It�s a bit outdated now but still available on sites like Vetusware. source

Using Converter Tools

Converter tools like XnView or AConvert can also open and convert ILBM files to more universal formats, like JPEG or PNG. source source

Usage in Video Games

ILBM file format is often used in video games due to its efficient use of memory. It was particularly popular in the Amiga series of computers in the late '80s and early '90s for this reason. source

Using in Amiga Computers

When working with Amiga, ILBM files can be opened with Amiga Forever - an Amiga emulator that allows users to run Amiga software on other platforms. source

ILBM File Important Information

When working with ILBM files, it's important to remember they are a raster file type, which means they store image data in pixel format. Because they use an 8-bit color palette, they are not suitable for high-quality graphics with a wide range of colors. However, for the very same reason, they make a good choice for simple graphics, especially in video games, where memory footprint is often a concern.
