Joint Photographic Experts Group (.jpg)

The JPEG (Joint Photographic Experts Group) file extension, abbreviated as JPG, is a widely used format for digital images. Originating from a standard established by the Joint Photographic Experts Group in 1992, it became the go-to choice for compressing photographic images due to its balance of compression and image quality. JPG files are particularly effective for web use, digital photography, and archival storage where color fidelity and small file size are paramount. This format's lossy compression reduces file size by discarding non-essential data, making it efficient for online image sharing and storage.

JPEG 2000 Code Stream Syntax (.j2k)

The J2K file extension stands for JPEG 2000 Code Stream Syntax, a part of the JPEG 2000 standard developed by the Joint Photographic Experts Group (JPEG). Introduced in 2000, JPEG 2000 offers superior image compression and quality compared to the original JPEG format. The J2K codestream is highly flexible, supporting both lossy and lossless compression, and allows for scalable decoding, which means images can be efficiently accessed at various resolutions and quality levels. This makes J2K ideal for applications requiring high-quality image storage and transmission, such as medical imaging, digital cinema, and satellite imagery.
