What is MIME type "image/x-homebrew-icon"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

image/x-homebrew-icon is a non-standard MIME type. It signals that a file holds a custom icon image made for homebrew applications.

These icons are used primarily in environments where users run custom software. The format provides a way to display small, pixelated graphics that serve as identifiers or buttons in a user interface.

Files with this MIME type typically use the extension HIC.

Primary use: Identifying custom icons in homebrew applications
Additional uses: Enhancing user interfaces in non-standard software environments; aiding in quick visual identification
Technical note: The x- prefix indicates an experimental or vendor-specific format

This MIME type helps systems and software know how to handle these images. For more details on MIME types, you can check out the IANA media types list.

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 are multiple MIME types listed for one extension?

Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
