Design Web Format (DWF) represents 2D/3D drawing in compressed format for viewing, reviewing, or printing design files. It contains graphics and text as part of design data and reduces the size of the file due to its compressed format. The reduced file size makes the distribution and communication of rich design data efficient. DWF doesn't require the recipient to know about the usage of CAD software that created the original drawing.
A JPEG is a type of image format that is saved using the method of lossy compression. The output image, as result of compression, is a trade-off between storage size and image quality. Users can adjust the compression level to achieve the desired quality level while at the same time reduce the storage size. Image quality is negligibly affected if 10:1 compression is applied to the image. The higher the compression value, the higher the degradation in image quality.
You can also convert DWF into many other file formats. Please see the complete list below.
