About .j2c Files
J2C files are a form of JPEG 2000 codestream images. They hold compressed image data using the JPEG 2000 standard.
Key features:
- Based on JPEG 2000 technology.
- Contain only the raw codestream data.
- Support both lossy and lossless compression.
- Used in applications that demand high image quality.
Usage details:
They are often used in professional imaging, scanning, and digital archiving.
Software such as Adobe Photoshop, IrfanView, ImageMagick, and XnView can open, view, or edit these files.
Based on information from FilExt.com, the MIME types associated with this format are:
- image/jp2 (JPEG 2000 Codestream)
- image/x-jp2-codestream (JPEG 2000 Codestream)
- image/jpm (JPEG 2000)
These MIME types confirm the file’s role in handling high-quality, compressed image data with minimal overhead.
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.
