DWG viewer FAQ
Which DWG versions can I open?
The browser reader accepts DWG R13 through the 2018 format (AC1012–AC1032). R13/R14 support is listed but not fully tested. R12 (AC1009) and earlier files are not supported. Conversion fidelity depends on the drawing’s entities, fonts and objects.
Will my drawing be uploaded to a server?
No. Your DWG is converted and previewed on this device; the file is not uploaded or saved to an account. The browser downloads the reader, viewer and font assets. This uses the same 20 MB DWG input limit as the online editor.
Can I use the DWG viewer on a phone?
You can try a small drawing in a current mobile browser with WebAssembly and WebGL2 support. Drag to pan and pinch to zoom. Memory and graphics support vary by device; a desktop browser is recommended for larger or complex drawings.
Can I edit a DWG directly in this browser viewer?
This page is for viewing only. To modify geometry or save a copy, use the online editor, which imports DWG locally and edits/saves DXF copies. Use the desktop download for the desktop DWG workflow.
