What 3D formats are supported?

GLTF and GLB files up to 40 MB. Single-file models that embed their textures and buffers (self-contained .gltf with data URIs, or .glb) work best.

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.

Must the GLTF reference external files?

No. This page reads the single file you upload. Models that reference external textures or .bin files cannot be loaded here — export a self-contained GLTF or GLB instead.

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.

Get a GLTF or GLB preview image online without a 3D viewer

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

How to get a 3D preview

Upload a GLTF or GLB 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.

What you get

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.

Supported models

This page renders with Blender's glTF importer:

.glb — the binary GLTF container. Best choice for upload.
self-contained .gltf — GLTF JSON whose textures and buffers are embedded as data URIs.

Models that point at external .bin or texture files cannot be loaded from a single upload — export a self-contained GLTF or GLB from your modeling tool first.

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.
