What is MIME type "image/jph"?

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

image/jph identifies images that follow the JPEG 2000 part 15 standard.
It compresses high-quality images with both lossy and lossless methods.
It suits workflows that need detailed and scalable imagery.

High Compression Efficiency: Maintains image quality while reducing file size.
Scalable Resolution: Supports both detailed and broad-scale views.
Advanced Imaging: Useful in professional digital imaging, archives, and medical contexts.
Interoperability: Works with software that recognizes JPEG 2000.

Files of this type use the JPH file extension.
For more details on the format, see the JPEG 2000 overview.

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.
