The .iff file extension is associated with 5 MIME types:
application/x-iff, image/x-ilbm, image/x-vff, audio/8svx, audio/x-8svx.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .iff Files
IFF files are a versatile container format developed in 1985 for bundling various media types.
They originate from the EA Interchange File Format and can include both images and audio.
- application/x-iff – A general container for multimedia data.
- image/x-ilbm – Stores interleaved bitmap images often used on vintage systems.
- image/x-vff – Holds Sun TAAC images, a bitmap-based image format.
- audio/8svx and audio/x-8svx – Used for 8-bit sampled voice data in audio files.
Applications like GIMP, Adobe Photoshop, and Audacity can open or edit these files.
Based on information from FilExt.com, IFF files remain a useful legacy format for creative and technical projects alike.
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 .iff file on Windows or Mac?
You need third-party software because modern operating systems do not support IFF natively. For IFF images (ILBM), use GIMP, XnView MP, or IrfanView. For IFF audio files (8SVX), use Audacity or VLC Media Player.
How can I convert an IFF image to JPG or PNG?
Open the file in a compatible editor like GIMP or XnView. Use the File > Export As menu to save the image as a standard .jpg or .png. Alternatively, online conversion tools can handle legacy formats associated with MIME types like image/x-ilbm.
Is an IFF file the same as an AIFF file?
No, although they share a similar structure. IFF (Interchange File Format) is a generic container often associated with Amiga computers, while AIFF (Audio Interchange File Format) is an audio-specific format developed by Apple. Most media players treat them as distinct file types.
Can Adobe Photoshop open .iff files?
Modern versions of Adobe Photoshop do not support standard IFF files natively. You will likely need to find a legacy format plugin or convert the file to TIFF or PNG using GIMP before editing it in Photoshop.
What is the correct MIME type for .iff files?
The MIME type depends on whether the file holds audio, video, or generic data. Common types include application/x-iff for containers, image/x-ilbm for images, and audio/8svx for audio. You can verify specific configurations at mime-type.com.
Why does my IFF file play as audio instead of showing an image?
IFF is a container format that can store either images (ILBM) or audio (8SVX). If your media player opens it, the file likely contains audio data. To view it as an image, ensure the file header indicates a bitmap format and open it with an image viewer like XnView.
Are .iff files dangerous to open?
generally, no, .iff files are passive media containers and not executable programs. However, like any file downloaded from the internet, they should be scanned for malware, as malicious code can theoretically be embedded in any container format.
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.
