JPEG

18.09.2024

Stands for Joint Photographic Experts Group, which is the name of the committee that created the standard. It is a widely used method of lossy compression for digital images, particularly for photographs and realistic images.

Main Features of JPEG:

Compression: JPEG uses a compression algorithm that reduces the size of an image by removing unnecessary information. This allows for a smaller file size, making it easier to transfer and store.
Lostless Compression: JPEG uses lossy compression, which means that some of the image information is lost during the compression process. This means that the image may lose some detail and clarity.
Color support: JPEG supports color images with a color depth of 24 bits (8 bits per RGB channel).
Transparency support: JPEG does not support transparency, which means that images with a transparent background will have a white background when saved as a JPEG.

Advantages of JPEG:

Small file size: JPEG allows images to be compressed to a relatively small size, making it ideal for sharing and storing images on the web.
Wide support: JPEG is supported by most browsers, operating systems, and image editors.
Good compatibility: JPEG can be used to store and share images across different devices and platforms.

Disadvantages JPEG:

Loss of quality: JPEG compression can result in a loss of image quality, especially when recompressed.
Not supporting transparency: JPEG does not support transparency, which can be a problem for images with transparent backgrounds.
Not suitable for graphics: JPEG is not suitable for graphics and text, as it loses detail and clarity.
