Extract text from Aleph One image files (IMGA)
To convert IMGA image files to another format, you need Aleph One or other Game software.
To convert other file formats to the "Game Engine Image Asset" file type, you need software like Aleph One or a similar tool.
The .IMGA file is an image asset archive used specifically by the Aleph One game engine, an open-source continuation of Bungie Studios' classic Marathon engine. These files store the 2D sprites, textures, and UI elements required to render the game world.
The .IMGA format has severe disadvantages for general use. It is a proprietary, closed-ecosystem archive that standard image viewers, web browsers, and design tools like Adobe Photoshop cannot open. The data relies on external color palettes and engine-specific indexing, making it frustratingly difficult to extract individual graphics. Users often need to convert these files to access the original artwork for fan projects, modding, or archival purposes.
To make these sprites usable, you must convert the archive into standard raster formats like PNG or JPG. Converting to PNG is recommended because it preserves the transparency of the game sprites, whereas JPG will fill transparent backgrounds with solid colors and introduce compression artifacts.
Standard online converters fail to process .IMGA files because they lack the specific parsing logic required for the Marathon 2 engine architecture. Often, only specialized modding tools like ShapeFusion can properly read or export the data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your IMGA file, detects the exact format, and lets you read the text inside.

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 IMGA converter.
