3Dstudio.co Web Tools
3Dstudio.co Web Tools is a suite of free, client-side 3D and CAD viewers and converters developed by architectural visualization studio 3Dstudio.co (Tallinn, Estonia). Designed for zero-friction workflows, all core file processing runs locally inside the user's browser using WebAssembly engines (Online3DViewer, web-ifc, occt-import-js, LibreDWG) with no account registration or file uploads to external servers. It supports viewing and inspecting architectural IFC (2x3, 4, 4.3), mechanical STEP/IGES, 3D printing STL/3MF meshes, AutoCAD DWG/DXF drawings, and native Revit/SolidWorks files, alongside vector PDF and 3D format conversion (18 input formats to 8 output formats).

The Pros
- 100% free with no account creation, sign-up, or watermark
- Strict client-side privacy: drawings and models are processed locally and never uploaded
- High-fidelity support across BIM (IFC), CAD (STEP/IGES/DWG), and 3D printing (STL/3MF)
- Fast and lightweight: runs smoothly on Windows, Mac, Linux, and Chromebook browsers
The Cons
- Read-only viewing and conversion utility with no parametric modeling or sketch editing capabilities
- Revit (.rvt) and SolidWorks (.sldprt) files utilize automated EU-based conversion service rather than pure in-browser parsing
- DXF vector export does not yet support complex polyline hatches
CADGuide Verdict
Final Professional Conclusion
"A privacy-first, zero-signup web toolkit that solves the everyday frustration of opening proprietary CAD, BIM, and 3D printing files without having to launch multi-gigabyte desktop software."
Expert Q&A
?What are 3Dstudio.co Web Tools?
3Dstudio.co Web Tools are a free collection of browser-based utilities developed by 3Dstudio.co in Estonia. They allow users to open, inspect, measure, and convert IFC, STEP, STL, DWG, DXF, and 3D models directly in modern web browsers without installation or user registration.
?Are files uploaded to external servers?
No. For IFC, STEP, IGES, STL, 3MF, DWG, DXF, and general 3D formats, all parsing, rendering, and conversion take place directly inside the user's browser using client-side WebAssembly. Files never leave the computer. The only exceptions are Revit (.rvt) and SolidWorks (.sldprt) files, which use an EU-hosted conversion pipeline with files automatically deleted within 24 hours.
?Which file formats are supported for 3D conversion?
The 3D converter reads 18 formats including STEP, IFC, FBX, OBJ, STL, glTF/GLB, 3DS, and 3DM, and can export to 8 formats including GLB, OBJ with MTL materials, STL, STEP, 3MF, and PLY.
?Does 3Dstudio.co Web Tools cost anything?
No. All tools are completely free to use with no hidden fees, subscriptions, or watermarks.
