About .mj2 Files
MJ2 files are a type of file that uses the JPEGÂ 2000 compression standard for video. They store sequences of still images as frames to create motion content.
The format is defined by the MIME type video/mj2. It builds on JPEG 2000’s still image technology, which is also seen in the MIME types image/jp2, image/jpm, and image/jpx.
- Main use: High-quality motion video storage with both lossy and lossless options.
- Additional uses: Digital cinema, professional video editing, and archival imaging.
- Software support: Media players like Apple’s QuickTime, FFmpeg-based applications, and other professional video tools can open or edit these files.
Each frame in an MJ2 file is compressed using JPEGÂ 2000 methods. This provides clear images even at high resolutions or when undergoing multiple edits. According to FilExt.com, MJ2 files are especially valued in workflows where maintaining image detail is critical.
Keep in mind that specialized software may be needed to fully utilize the format’s capabilities.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

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 can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
