About CAD Viewer
Updated · Local release information
These explanations and translations have not been reviewed by a qualified legal professional. The retained English reference describes this local release; the original software and font license texts govern the components they cover. Public operation still requires review of the operator, jurisdiction, hosting and any future advertising or analytics.
Free Online DWG & DXF Viewer
Open, measure and annotate CAD drawings directly in your browser. No sign-up required.
Drawing tools
View DWG and DXF drawings, inspect layers, measure geometry and keep review annotations on this device. Export DXF, PDF and images where supported. Save Annotations keeps review data separately from your source drawing.
DWG writing is currently unavailable. Compatibility depends on the drawing's version and entities; some splines, leaders, external references and engineering fonts may display differently.
Built with open-source software
The working CAD engine includes GNU LibreDWG, mlightcad and Three.js. Read the open-source notices for attribution and source information.
Free access and hosting
The viewer's current tools are free to use. Advertising may be introduced outside the interactive drawing workspace in a future release. This deployment contains no AdSense advertising code. The website is hosted on Cloudflare Pages and already uses Cloudflare Web Analytics for page visits and performance. Read the Privacy Policy for hosting data handling and the operator details still awaiting legal review.
