What 3D formats are supported?

OBJ files (Wavefront OBJ) up to 40 MB. This is the most common 3D model format.

Can I control the thumbnail size?

Yes. Pick small (200×200), medium (400×400), or large (800×600). Medium is a good default for most uses.

Does this keep the model as a 3D file?

No. You get a flat PNG picture of the model, not the model itself. Use it when you need a quick preview or an image to share.

Need a quick look at a 3D model without opening a 3D viewer? This page turns an OBJ 3D model into a thumbnail PNG you can use right away.

How to get a 3D preview

Upload an OBJ file up to 40 MB.
Pick a thumbnail size (small, medium, or large).
Choose whether you want a solid background or transparency.
Press Convert file and download the PNG.

A PNG image of your 3D model. The model is automatically centered and framed. You can use the thumbnail for a catalog, a slide, or a quick visual check.

When this helps

Adding model previews to a product catalog or portfolio
Quickly checking a 3D model without opening a 3D viewer
Generating shareable images of models for chat or documentation
Creating thumbnails for a model library or asset browser

This is a flat preview, not a 3D viewer. If you need to inspect or edit the model surface, use a desktop 3D application instead.
