Why convert EMZ to DWG?
An EMZ (GZIP-compressed Enhanced Metafile) contains GDI rendering commands - a rendered picture, not CAD data. A DWG requires geometric entities with coordinates in model space, layer properties, dimensions with tolerances, and optionally 3D geometry. None of that structure exists in an EMZ; any 'conversion' would require software to infer which strokes are walls, which are dimensions, and which text is annotation - a task no tool does reliably.
How to convert EMZ to DWG
XnView FREE
Convert the .emz to PNG in XnView (File → Save As → PNG), then attach the PNG in AutoCAD as an image underlay using the IMAGEATTACH command to use it as a tracing reference.
LibreOffice Draw OPEN-SOURCE
Open the .emz in LibreOffice Draw and export as PNG (File → Export), then import the PNG into AutoCAD via IMAGEATTACH and trace geometry manually over the underlay.

Open .DWG details →Quality & what to watch
- Any tool marketed as an 'EMZ to DWG converter' embeds the rasterized image as a single object inside the DWG - not real CAD geometry with editable entities.
- Tracing a PNG underlay in AutoCAD manually is a last resort; for drawings with precise dimensions, obtain the original DWG or DXF source file instead.
- EMZ is a flat visual record - CAD layer structure, dimension tolerances, and block definitions do not exist in the file and cannot be recovered.
