Convert & Compress Page

Learn how to use the convert & compress page.

On this page, you can process 3D assets, convert between formats, compress and optimize files, and generate 2D thumbnails.

Supported file formats:

  1. Models: .obj, .stl, .fbx, .glTf, .glb, .usd, .usda, .usdc, .usdz, .ply, .dae, .zip, and more. We recommend using .glb or .fbx with the textures baked in.

  2. Videos: .mp4, .mov

  3. Images: .png, .jpg, .gif, .svg

The maximum allowed file size is 25MB for the free plan and unlimited for paid plans.

When adding multiple assets from local storage, we recommend zipping them first and uploading the ZIP file. When selecting models, be sure to include all files associated with that model (i.e., include material and texture files in your selection). An uploaded 3D model will automatically be centered around its origin.
