What is MIME type "image/jpx"?

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

The MIME type image/jpx is used for images encoded in the JPEG 2000 format. It supports both lossy and lossless compression. This makes it suitable for high-quality images with efficient file sizes.

Files in this format often use file extensions such as JP2, JPF, JPM, JPX, and MJ2.

• Advanced Compression: Enables both high compression ratios and preservation of fine details.
• Multi-Resolution Support: Allows images to be viewed at different scales without re-encoding.
• Enhanced Features: Supports alpha channels and improved color management.
• Professional Applications: Widely used in fields such as medical imaging, digital cinema, and geographic data systems.

The image/jpx MIME type leverages the modern capabilities of JPEG 2000 standards to deliver better image quality and more flexibility compared to older formats.
