About .ilbm Files
ILBM files are image files that store bitmap data in an interleaved format.
They use the MIME type image/x-ilbm and belong to the IFF family of file formats.
These files store pixel information in separate color planes that merge during display. This method was favored in early computer systems such as the Amiga.
- Retro Graphics: Widely used for graphics and animations in vintage computing and demo scenes.
- Digital Art: Employed by artists working with pixel-based images and retro game design.
- Software Support: Openable with legacy Amiga applications and modern viewers like IrfanView or XnView.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
How do I open an ILBM file on Windows?
You can open ILBM files using versatile image viewers like IrfanView (with the plugins pack installed) or XnView MP. These programs can read the legacy interleaved bitmap format and display the image correctly.
Can I convert ILBM files to PNG or JPG?
Yes, you can convert ILBM files to modern formats like PNG or JPG using XnConvert or IrfanView. Converting to PNG is recommended to preserve the sharp, pixel-perfect quality of the original retro graphics.
What is the relationship between ILBM and IFF files?
ILBM (InterLeaved BitMap) is a specific type of data chunk found within the IFF (Interchange File Format) container. While IFF is the general container format used by Amiga systems, ILBM specifically refers to the image data stored inside it.
Why can't Adobe Photoshop open my ILBM file?
Modern versions of Adobe Photoshop do not natively support the Amiga ILBM format. To edit these files in Photoshop, you must first convert them to a supported format like TIFF or PNG using a third-party converter or find a specialized legacy file format plugin.
What is the MIME type for ILBM files?
The standard media type for these files is image/x-ilbm. You can look up more details about this configuration and related formats on mime-type.com.
How do I view ILBM files on macOS?
Mac users can view and convert ILBM files using GraphicConverter, a long-standing utility known for handling legacy formats. Alternatively, cross-platform tools like XnView MP are also available for macOS.
Are ILBM files compressed?
Yes, ILBM files often use a form of Run-Length Encoding (RLE) compression known as ByteRun1. This lossless compression was efficient for the hardware capabilities of early computers like the Commodore Amiga.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
