JPG is a common file format for digital images, also abbreviated as JPEG. The abbreviation stands for Joint Photographic Experts Group, a group of experts who developed the format in 1992. JPG files are often used in photography and graphic design because they offer a good balance between file size and image quality. The JPG format is a lossy compression format, which means that the file size is reduced by removing data that is not perceptible to the human eye. However, this compression is not without losses, as some details in the image can be lost. This can lead to a decrease in image quality with high compression, known as compression artifacts. JPG files can typically be opened and edited with a variety of image editing programs. The format is also widely used on the internet because it can load quickly due to its small file size. However, JPG files also have their limitations, especially when it comes to post-processing. Since the format is lossy, editing the image can further degrade the quality. For this reason, it is often recommended to save the original image in RAW format, if available, to ensure maximum flexibility in post-processing.
