How to open JPG Files


The File extension jpg is used by the following type(s):

Default file extension for .jpg file type: JPEG bitmap image format files

The JPG file extension is associated with JPEG (Joint Photographic Experts Group) file format. JPEG is a lossy image compression algorithm that significantly reduces the file size of the original image at the cost of quality. The higher the compression ratio the lower the quality of the .jpg files.

JPEG is based on a 24-bit color palette and supports 16.7 million colors. However it is a lossy compression format, which means that it drops information that is compressed out. Compression ratios may range from 10:1 to 20:1 and most graphic application programs (such as Adobe Photoshop) allow you to choose the compression rate.

The JPEG file format is best suited for digital photographs, where the typical compressional rate with very low quality loss is around 10:1.

MIME: image/jpeg, image/jpg, application/jpg, application/x-jpg
