FastDWG: DWG Viewer & Reader

FastDWG is a fast, fully offline viewer for AutoCAD DWG and DXF drawings. Open a drawing, browse its layers, measure real distances in the drawing's own units, and export to PDF — all on your device, with nothing uploaded anywhere.

WHY FASTDWG
• Fully offline — no account, no sign-in, no internet permission.
• No ads, no tracking, no advertising ID.
• Your drawings never leave your phone.

OPEN REAL DRAWINGS
• Supports modern DWG (AutoCAD 2013–2025) and DXF files.
• Opens drawings straight from your file manager, email, or any app that shares a .dwg / .dxf file.
• Shows the drawing's embedded preview instantly while the full file loads in the background.

WORK WITH YOUR DRAWING
• Smooth pan and zoom, even on large drawings.
• Turn layers on and off; zoom to a single layer.
• Measure distances in the drawing's real units.
• Clean, readable rendering with true colors and line weights.

EXPORT & SHARE
• Export to PDF at real paper sizes (A4, A3, A2, A1, A0).
• Share drawings and exports to any app.

FastDWG is built for engineers, architects, contractors, and anyone who needs to check a CAD drawing quickly on the go — without a heavy desktop program.
