About .jng Files
JNG files are a type of media file based on the JPEG Network Graphics format. They can serve both as still images and as parts of animated sequences.
- Format details: JNG separates image data into two streams—a JPEG portion for the main image and an extra stream for alpha channel or additional data.
- MIME types: They are identified as video/x-jng when used for video-like content and as image/jng or image/x-jng for static images.
- Use cases: Suitable for web graphics requiring both quality and transparency, and for animations within the MNG (Multiple-image Network Graphics) family.
- Software support: Programs like GIMP or Adobe Photoshop (with appropriate plugins) and some specialized media players can open and edit these files.
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.
