What is MIME type "image/jp2"?

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

The MIME type image/jp2 represents the JPEG 2000 image format. It uses advanced compression to keep file sizes small while preserving image quality.
It supports both lossless and lossy compression methods, which means you can maintain high detail or reduce file size as needed.

Offers superior compression compared to legacy JPEG.
Handles high-resolution and high-dynamic-range images well.
Enables features like tiling and region-of-interest decoding.
Is used in professional areas such as digital cinema, medical imaging, and geospatial analysis.

This MIME type is linked to various file formats such as JP2, JPF, JPM, JPX, J2K, JPC, J2C, JPG2 and MJ2.
This makes it versatile for both still images and motion content in professional settings.

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.
