About .igi Files
IGI files are binary files associated with the Indigo Image format.
They use the MIME type application/octet-stream to indicate a stream of raw binary data.
This file type is mainly used to store specialized image or texture data for applications that rely on the Indigo image system.
- Primary use: Contains binary data for image rendering in specific graphics software.
- Viewing/Editing: Requires specialized viewers or editors that support the Indigo Image format.
- Conversion: Often needs to be converted to common formats for broader compatibility.
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
What is an .igi file?
An .igi file is a proprietary image format associated with Indigo Renderer, a photorealistic rendering engine. It stores high-dynamic-range (HDR) image data and lighting information used to pause, resume, or tweak renders without losing quality.
How do I open an IGI file?
You need to use Glare Technologies Indigo Renderer to open and view these files properly. Since it is a specialized format for 3D rendering, standard photo viewers like Microsoft Photos or macOS Preview will not recognize it.
Can I convert an IGI file to JPG or PNG?
Yes, but you usually need to open the file in Indigo Renderer first. Once the image is loaded in the Indigo interface, you can save or export the render to common formats like PNG, JPG, or TIFF for easier sharing.
Why is the MIME type listed as application/octet-stream?
The IGI format does not have a standard registered MIME type, so servers often default to application/octet-stream. This indicates the file is a stream of raw binary data; you can find more details about this generic type at mime-type.com.
Can Adobe Photoshop open IGI files?
Adobe Photoshop does not support the .igi extension natively. To edit the image in Photoshop, you must first convert it to a compatible format (like EXR or TIFF) using the Indigo Renderer software.
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.
