Frequently asked questions
Is my 3D model file uploaded to a server?
The selected 3D 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.
What tools are included?
A free online 3D viewer for 15 file formats, a file converter covering 128 distinct format pairs, and a local 3D text generator. All three tools run in your browser.
Is the 3D toolkit 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.

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.
