ImgConvert is an add-on utility allowing to convert raster images to internal 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. This is a full, unlimited version of the tool.
