Questions
Is my file uploaded?
No. The viewer runs in your browser; the drawing is read from your disk and nothing is sent to a server.
Which DWG versions open?
Most DWG files from recent AutoCAD versions. If one won’t open, save it as DXF from your CAD program and try again.
Is it free?
Yes, every tool on this page is free.
Can I open drawings on my phone?
DWG Viewer for Android opens drawings straight from Files, Drive, Gmail or WhatsApp, offline. Get it on Google Play.
