What is MIME type "text/vnd.ascii-art"?

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

The MIME type text/vnd.ascii-art designates a plain text format meant for ASCII art—images created using simple text characters.

It tells systems that the file contains artistic layouts made solely from standard text. This makes it ideal for environments with limited graphic support or where text rendering is preferable.

Artistic Expression – Files display creative images using only characters.
Compatibility – Easily viewed and edited with any text editor.
Legacy Use – Common on older systems, bulletin boards, and email art.

Typical files use this MIME type include TXT, ASC, and ASCII. Each offers a way to store and share text-based images in a standardized manner.

The declaration of this MIME type helps applications process the file as art rather than simple text, ensuring proper display in supported contexts.

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.
