Frequently asked questions

Is my source model file uploaded to a server?

The selected source model file is processed by the browser and is not uploaded to Modelfy. Website code and static assets still load over the network like a normal web page.

Which conversions are supported?

Mesh formats (GLB, GLTF, OBJ, STL, PLY, FBX, 3MF, USDZ, VOX, DXF) and images (PNG, JPG, JPEG, WEBP, BMP, GIF, TIFF, SVG) can all be converted to 3MF, DXF, GLB, GLTF, OBJ, PLY, STL, or USDZ.

How are images converted to 3D?

Raster images become embossed relief models: bright pixels rise, dark pixels stay low, on a solid printable base. SVG files are extruded from their filled vector shapes instead, giving sharp clean edges.

Is the 3D file converter free to use?

Yes. The browser viewer, converter, and local 3D text tool require no account and add no watermark. Input limits vary by format, up to 50 MB; AI model generation is a separate credit-based product.

AI 3D generation

From a single image to a production-ready 3D model

These browser tools stay free for viewing and converting files you already have. When the model does not exist yet, Modelfy generates a textured mesh from one reference image — the first one is free.
