The tools

Screenshots and descriptions of each tool

Each description is about 60 words. Click an image to open it at full size.

Free IFC viewer

A free IFC viewer that runs in the browser. It opens IFC 2x3, IFC4 and IFC4.3 files from Revit, Archicad, Tekla and Vectorworks, lists every element by type and level, shows each element's IFC properties and property sets, and measures distances. The model is opened on the user's own computer and is never uploaded. No sign-up.

Free STEP viewer

A free STEP and IGES viewer for mechanical CAD files from SolidWorks, Fusion 360, Inventor and CATIA. It lists every part of an assembly, shows the size, volume and printed weight, checks whether each part is a closed solid, and measures in millimetres. The file stays on the user's computer. Free, no sign-up, nothing to install.

Open the STEP viewer

Free STL viewer

A free STL viewer for 3D printing. Drop an STL or 3MF file to see its size, volume and solid PLA weight, check whether the mesh is watertight, and measure between any 2 points. It also opens OBJ, STEP and glTF files. Everything runs in the browser, so files are never uploaded. Free, with no sign-up.

Free DWG to PDF

A free DWG to PDF converter. It reads AutoCAD DWG files from R13 to the 2018 format and plots every layout 1:1 on its own sheet size, with line weights, line types, hatches, blocks, text and dimensions, into one vector PDF. It runs in the browser, so drawings are never uploaded. DXF files are not supported yet. Free, no sign-up.

Free Normal map generator

A free normal map generator. Drop a photo or a texture to get a normal map in OpenGL or DirectX format, a height (displacement) map, a roughness map and an ambient occlusion map, with a lit preview and a seamless option for tiling. All maps download in one ZIP, up to 2048 px. The image is never uploaded. Free, no sign-up.

Free 3D converter

A free 3D model converter that reads 18 formats, including STEP, IFC, FBX, OBJ, STL, glTF, 3DS and 3DM, and saves 8, including GLB, OBJ with materials, STL and STEP. It checks whether the result is watertight before saving. The conversion runs on the user's own computer, so files are never uploaded. Free, no sign-up.

Open the 3D converter

Free STL converter

A free STL converter for 3D printing. It turns STEP, OBJ, FBX, IFC, glTF and other 3D files into binary STL, reports the size and whether the mesh is watertight, and can also turn a photo or drawing into a relief STL or a lithophane. It runs in the browser and files are never uploaded. Free, no sign-up.

Open the STL converter

Free OBJ converter

A free OBJ converter. It converts STL, FBX, STEP, glTF, 3DS and IFC files to OBJ with an MTL material file, zipped together with the textures, and converts OBJ files to GLB, STL or STEP. It runs in the browser, so the model never leaves the user's computer. Free, no sign-up.

Open the OBJ converter

Free FBX converter

A free FBX converter for files from 3ds Max, Maya, Blender and Cinema 4D. It converts FBX to GLB, OBJ with materials or STL, for use on the web, in other 3D programs or for 3D printing. It runs in the browser, so files are never uploaded. It cannot save FBX files. Free, no sign-up.
