glTF is a one-size fits all file format designed to let you move 3D files seamlessly between applications while retaining a consistent PBR workflow.
We offer glTF as the standard export for all downloadable models in addition to
the original file format that was uploaded.
That's over 300,000 models currently available for free download under Creative Commons licensing and many more on the Sketchfab Store.
Since Sketchfab accepts all major 3D file formats for upload, our glTF export also means we provide the easiest way to convert a 3D file from one of our supported formats into glTF. You can use this to convert your own content if you need a glTF output.
