Convert STL to an animated GIF
Turn an STL into a looping turntable GIF in your browser — the quickest way to show a print before it is printed.
Formats it opens
- STL
Anything else is refused when you choose it rather than failing halfway through. See every format MeshCrunch supports.
Limits and privacy
- Opens models up to 50 MB without an account.
- Your model is stored privately in your own workspace and deleted after 24 hours unless you sign in.
- Uses none of your processing credits: viewing and spinning a model are done by your browser, not by a server.
Every frame of your STL turntable is rendered and encoded by this browser, so it costs no processing credits. The file itself goes to your own private workspace, which needs no account and is cleared after 24 hours.
How it works
- 1
Drop in your STL file
The STL goes straight to your private workspace and opens on the Turntable tab. No account, and no processing credit.
- 2
Set the spin
Pick a preset, or set duration, direction, resolution and frame rate. The preview is the real renderer, so what you see is what encodes.
- 3
Export a GIF or MP4
Write a looping GIF, an MP4 where your browser has the encoder, or a single PNG still with a transparent background.
What to expect from STL files
- STL carries triangles and nothing else: no materials, no textures, no colours. The tool applies a neutral studio material so the shape reads.
- STL declares no units, which does not matter here — the camera frames whatever it is given.
- Faceting you see is genuinely in the mesh. STL stores flat triangles, and no smoothing is invented.
- The result is a 2D animation of the model. It is not a converted 3D file.
Frequently asked questions
Can I change the colour of the model in the GIF?
Not per-material, because an STL has no materials to colour. What you can change is the backdrop and the lighting environment, which is what makes a print read as metal, resin, or clay.
Does binary or ASCII STL matter?
No. Both load. Binary files are far smaller for the same mesh, so a large ASCII STL is worth re-exporting as binary before it reaches the size limit.
Is this a good way to show a print to a client?
Yes — a rotating loop shows overhangs and wall thickness that a single render hides, and it plays inline in an email or a chat without a viewer plugin.
Where does my STL file go?
To private storage only you can reach, so the workspace can open it — never anywhere public, and deleted after 24 hours unless you sign in. The animation itself is rendered and encoded by your own browser, which is why it uses no processing credits.
