What is MIME type "application/x-subrip"?

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

application/x-subrip is the MIME type for the SubRip subtitle format.
It indicates plain text files that hold time-coded subtitles. These files contain text lines and timing data that instruct video players when to show each subtitle.

Main use case: Displaying subtitles during video playback.
Other uses: Editing and translating subtitle content, and providing accessibility options.
Typical association: Files using the SRT extension.

The format is simple and human-readable. It uses basic timing (start and end times) to sync text with video.
Many media players and subtitle editors support this MIME type because it is easy to create and modify.

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.
