3dfileconverter.online is a free browser workspace for converting and inspecting OBJ, STL and STEP models. Convert formats, view models, resize and rotate meshes, simplify geometry, check mesh edges, measure distances, export separate parts and capture PNG views. Batch conversion handles up to 10 files. Model files are processed on your device, with no conversion-server uploads or account required. Inputs are limited to 50 MB per file, and operation-specific limits apply. STL-to-STEP produces faceted surface shells, not reconstructed parametric CAD solids. External OBJ textures are not imported. Validate exported models in your target software.
