Most image capture devices (such as digital cameras) that output JPEG are actually creating files in the Exif format, the format that the camera industry has standardized on for metadata interchange. Image files that employ JPEG compression are commonly called "JPEG files", and are stored in variants of the JIF image format. JPEG typically achieves 10:1 compression with little perceptible loss in image quality.īinary DOC files often contain more text formatting information (as well as scripts and undo information) than some other document file formats like Rich Text Format and HyperText Markup Language, but are usually less widely compatible. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. In Microsoft Word 2007 and later, the binary file format was replaced as the default format by the Office Open XML format, though Microsoft Word can still produce DOC files. DOC is a filename extension for word processing documents, most commonly in the proprietary Microsoft Word Binary File Format.
