SmartCAD · Free Online Tools
Eight free tools for 2D drawings and 3D models. Files never leave your device — everything runs locally with WebAssembly.
Drag in a DWG, DXF or 3D model — or click to browse. Loads in seconds.
Parsing and conversion run in your browser with WebAssembly — nothing is uploaded.
Save the converted file — or keep editing and export when ready.
