Free 3D tools

No account, no card. The viewer and the GIF maker render your model in your own browser and cost no processing credits; the converter runs on our servers and uses one.

3D model viewer

Free · Live

Open GLB, glTF, OBJ, STL or PLY and inspect the geometry — orbit, wireframe, grid, triangle and vertex counts.

Renders in your browser · no processing credits

Open 3D Viewer

3D mesh inspector

Free · Live

Find what is wrong with a model — non-manifold edges, holes, winding, missing UVs — and whether it fits the platform you are shipping to.

Runs in your browser · no processing credits

Inspect a model

Conversions with their own guide

Each page explains what survives the conversion and what does not, and runs the same converter.

What "free" means here

  • The viewer and GIF maker draw every frame in your own browser, so they use no processing credits at all.
  • All three put the file itself in private storage so the workspace can open it: up to 50 MB per file, 3 server jobs such as a conversion per rolling 24 hours without an account, and everything deleted after 24 hours unless you sign in — signing in claims those uploads and keeps them for 7 days.
  • No card, and no signup wall in front of a result you were promised.
