Do You Need a 3D File or a Screenshot for Rendering?
Either one works. If you have a 3D file in GLB, GLTF, OBJ or STL format, upload it to 3D Model to Render. If you only have a screenshot, image or sketch of your model, use Image to Render or Sketch to Render instead. A screenshot is faster and works with any software.

You can use either one. Rendair works with a 3D file, or with a screenshot or image of your model.
If you have a 3D file
Upload it to 3D Model to Render. Rendair accepts GLB, GLTF, OBJ and STL files up to 100 MB. It keeps the shapes of your model and adds materials, light and context.
If you only have a screenshot or image
Use Image to Render, or Sketch to Render if your image is a drawing. Take a clear screenshot of the view you want, save it as JPG or PNG, and upload it. This is faster and works with any software.
Which should you choose?
- Choose a screenshot when you want a quick result, or when your software cannot export a 3D file.
- Choose a 3D file when you want Rendair to work from the model itself.
