Extract text from image libraries (ILB)
To convert ILB libraries to another format, you need Heroes of Might and Magic III or other Game software.
To convert other file formats to the "Asset Container" file type, you need software like Heroes of Might and Magic III or a similar tool.
The .ILB file extension is a digital container primarily utilized as a Game Image Library or asset archive. It is most famously associated with classic turn-based strategy titles like Heroes of Might and Magic III and Fantasy General, where it acts as a consolidated warehouse for thousands of sprite animations, terrain textures, and user interface elements. In the industrial sector, .ILB files serve a completely different function as HMI Graphical Component Libraries generated by Mitsubishi Electric GT Designer software, storing reusable touch panel interface objects.
The primary frustration with .ILB files is their proprietary "black box" nature. They are not standard archives like ZIP or RAR; they are custom-compiled binary blobs optimized for specific engines. Users cannot simply open them in Adobe Photoshop or Windows Photos. Accessing the content typically requires niche modding utilities (such as MMArchive for HoMM3) or expensive proprietary industrial software. This lock-in makes it difficult to view assets, mod games, or migrate industrial designs to newer platforms.
For gamers and modders, the best workflow is converting or "extracting" the internal assets to standard formats like PNG or BMP to preserve transparency and pixel fidelity. For preservation of older Amiga-style graphics (often identified as IFF InterLeaved Bitmaps), converting to TIFF or PNG ensures the artwork remains viewable on modern displays.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ILB converter.
