What is MIME type "application/x-ogg"?
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
application/x-ogg is a MIME type for files using the Ogg container format. It tells your system how to handle the fileโs data. This type mainly handles compressed audio, often with the Ogg Vorbis codec, though it can also carry video and text.
- Purpose: It packages digital media streams in a flexible container format.
- Streaming: Its design supports smooth streaming over the internet.
- Flexibility: It can encapsulate audio, video, and metadata.
- Open Standard: It is based on open and royalty-free technology.
This MIME type is commonly used by files like OGG, which typically hold compressed audio data.
Some related file types such as OGX use a similar standard (application/ogg) to provide added functionality or to encapsulate other data types.
For more technical details, see the IANA media types registry.

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.
