| Format introduction | DWG is a proprietary binary file format used for storing two- and three- dimensional design data and metadata. It is the native format for several CAD packages including DraftSight, AutoCAD, IntelliCAD, Caddie and Open Design Alliance compliant applications. In addition, DWG is supported non-natively by many other CAD applications. | JPEG is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. |
| Technical details | DWG contains all the pieces of information a user enters, such as: Designs, Geometric data, Maps, Photos. The .dwg file format is one of the most commonly used design data formats, found in nearly every design environment. The DWG technology environment contains the capability to mold, render, draw, annotate, and measure. | Image files that employ JPEG compression are commonly called "JPEG files", and are stored in variants of the JIF image format. 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. |
