Check our videoThe JPM format is a part of the JPEG 2000 standard, designed for efficient storage and transmission of high-quality images, particularly for compound documents containing multiple images or pages. It is supported by applications like Adobe Photoshop, GIMP, and specialized tools such as Kakadu and OpenJPEG, often used in medical imaging, digital archiving, and document management. The format utilizes JPEG 2000 compression for individual images and organizes them into a hierarchical structure, supporting advanced features like multi-resolution encoding, region-of-interest coding, and metadata embedding for enhanced flexibility and scalability.
