What you can do in the viewer

The file is read on our servers and streamed to your browser as vector linework, so it stays sharp at any zoom.

  • Large drawings stay usable

    Geometry streams in largest pieces first, and panning moves a cached frame, so plans with millions of objects stay smooth.

  • Every layer, with its colour

    Hide walls, furniture or annotations in the Layers panel to read one part of the drawing at a time.

  • Coordinates in drawing units

    The X and Y under your cursor are shown in the drawing’s own units: millimetres, metres, inches or feet.

  • Phones and tablets

    Pinch to zoom and drag to pan. The page works the same in Safari, Chrome, Edge and Firefox.

  • Private files

    Files you open are kept private. Nothing appears in the library unless you share it yourself.

  • My files

    Sign in to save a drawing and open it again later from another computer or your phone.

Common questions

Is the DWG viewer really free?

Yes. Viewing DWG and DXF files is free, with no account, watermark or trial. Signing in (also free) only adds saving files to your own cloud storage.

Which DWG versions can I open?

DWG files saved by AutoCAD 2000 or newer, including the AutoCAD 2018 format used by all current releases. Older R14 and R12 files need to be re-saved in a newer format first.

Are my files private?

Yes. Files you open are processed on our servers and stored privately. They are never published or shown to other people. Only you can share a file, by choosing to publish it to the library.

Can I edit the drawing?

The web viewer is for viewing. To edit, measure, dimension or export a drawing, open it in SmartCAD 2D for Windows, which reads and writes DWG and DXF and has a free plan.

Does it work on iPhone, iPad and Android?

Yes. The viewer runs in the browser, so you can open DWG files on phones and tablets and pinch to zoom.

How large can the file be?

Up to 50 MB. For bigger drawings, use SmartCAD 2D on Windows.
