ImgConvert is an add-on utility allowing to conversation raster images to internal Autodesk® AutoCAD® blocks. So you can embed attached (external) raster images into your DWG drawings - the resulting DWG file will no more depend on external references. Both monochrome and color images are supported, in any raster file format. There is a penalty in file size - larger images may grow your DWG files substantially. ImgConvert also contains tools to draw and embed QR Codes (2D matrix bar codes) in your DWGs.
