DWG / DXF viewer

Open AutoCAD DWG and DXF drawings in your browser.

Files

If DWG fails, open the same drawing in CAD and save as DXF.

About this tool

Preview AutoCAD DWG and DXF drawings without installing desktop CAD software. Upload a file and see lines, arcs and polylines rendered on a canvas — entirely in your browser.

Why use it

  • Opens common DWG and DXF files locally.
  • No server upload — suitable for confidential plans.
  • Quick check before sending drawings to a colleague.

Common use cases

  • Verify a DWG attachment on a machine without AutoCAD.
  • Preview a DXF export from a design tool.
  • Quickly inspect layer geometry before site review.

Tips

  • Complex drawings with custom objects may show partially — LibreDWG limits apply.
  • For best results use standard LINE, CIRCLE, ARC and LWPOLYLINE entities.
How to use
  1. Drop a .dwg or .dxf file.
  2. Wait for parsing.
  3. Pan the preview canvas.
FAQ
Which file types are supported?
DWG and DXF drawings are supported for preview in your browser.
Is my CAD file uploaded?
No. Parsing and rendering happen locally on your device.
Why is part of my drawing missing?
Custom or proprietary CAD entities may not render; standard lines, circles and arcs usually do.
Can I edit the drawing?
This is a viewer only — you can preview geometry, not modify or save DWG.
Does it open very old DWG versions?
LibreDWG supports many versions but some files may fail; try exporting DXF from your CAD app.
Can I download a PNG of the view?
Use your browser screenshot tools; a dedicated export may be added later.
