3D Model to Video Converter
Open a 3D model and get a turntable video of it: GLB to MP4, STL to MP4 and more. The model is rendered and recorded in your browser, so the file is never uploaded and there is no watermark.
How to turn a 3D model into a video
- 1
Open your model
Drop a GLB, STL, OBJ, PLY, 3MF or FBX file, or press the sample button to try the toy robot.
- 2
Set the shot
Pick the spin direction, camera height, zoom, colour for plain meshes like STL, and a solid or gradient background.
- 3
Pick size and speed
Choose 480p to 1080p, 10 to 30 frames per second, seconds per turn and how many turns the video shows.
- 4
Make the video
Press Make video. Recording happens in real time, so a 4-second turn takes about 4 seconds, then download the file.
Video output options
What you can set and what to expect from each browser.
| Input formats | GLB, STL, OBJ, PLY, 3MF and FBX. Textures inside a GLB are kept; for a .gltf with separate files, pack it into one GLB first. STL and other plain meshes use the colour you pick. |
|---|---|
| Video format | MP4 (H.264) where your browser can record it, which includes recent Chrome, Edge and Safari. Otherwise WebM, which plays in browsers, VLC and most editors. The format list only shows what your browser can really make. |
| Resolution | 256, 480, 720 or 1080 px on the long side. Phones are capped at 720 px to stay within memory. |
| Frame rate and length | 10, 15, 24 or 30 fps; 2-10 seconds per turn; 1, 2 or 3 turns per video. |
| Background | A solid colour or a two-colour gradient. Videos cannot be transparent here, so a transparent background is recorded as black; use the GIF or PNG frames output for transparency. |
| Other outputs | The same tool can also make an animated GIF or a ZIP of PNG frames from the same shot. |
| Privacy | Nothing is uploaded. The model is loaded, rendered and recorded on your device. |
Why make a turntable video?
A short spinning video is the easiest way to show a 3D model to someone who does not have a 3D viewer: for a portfolio, a product listing, a print shop page, a client preview or a social post. MP4 plays almost everywhere, including phones, chat apps and video sites.
Recording the screen while you rotate a model by hand gives shaky, uneven results. A turntable renders every frame at the same speed and angle, so the loop is smooth and the model stays centred.
GLB to MP4, STL to MP4 and other formats
For GLB files the materials and textures you exported are shown as they are. For STL, OBJ without materials, PLY and 3MF, pick a model colour and a contrasting background so the shape reads clearly.
If your browser saves WebM and you need MP4 for an app that does not accept WebM, open the page in a recent Chrome, Edge or Safari, or convert the WebM file with a video converter. The video quality is the same; only the container and codec differ.
Tips for a good-looking video
Use 1080 px and 30 fps for portfolios and listings, and 720 px for chat apps and quick previews. A slight camera height (looking a little down at the model) usually shows its shape better than a flat side view.
Most GLB files use Y up, while STL and 3MF files from CAD and slicers use Z up; the tool guesses this from the file type. If the model lies on its side, tick "Z is up" (or untick it) to stand it upright.
No 3D model yet?
Make one from a photo or a text prompt with AI, then come back and turn it into a video.
