What Online 3D Converter is
Online 3D Converter changes 3D models between supported file formats in a browser. Users can drag and drop a model or open one from their device, then convert it without installing software. Its listed formats include 3DM, 3DS, 3MF, AMF, BIM, BREP, DAE, FBX, FCSTD, GLTF, IFC, IGES, STEP, STL, OBJ, OFF, PLY, and WRML. The site says conversion happens entirely in the browser and files are never uploaded. Conversions are usually instant, although speed depends mainly on file size and complexity. The tool works on most modern mobile browsers, but very large files may run more smoothly on desktop devices. It is free and displays advertisements to help fund hosting and maintenance. Example models are available for several formats, including 3DM, 3DS, 3MF, FBX, STEP, STL, and OBJ. For visualizing models, taking measurements, and calculations, the site points users to a related 3D Viewer tool.
