Sketchfab adds USDZ 3D file conversion

Back to overview

Every single downloadable model on Sketchfab is now available in the Apple and Pixar developed USDZ format. This includes both free Creative Commons licensed models as well as royalty-free models on the Sketchfab Store.

With over 400,000 USDZ files instantly available for download, this makes Sketchfab the largest and most diverse library of USDZ files. Additionally, if you are a subscriber to Sketchfab Pro or above all your own models are also now privately available to you for download in this format too. Click the download icon in the top right of this model embed to access the USDZ file:

Sketchfab was featured in 2018 when Apple introduced the open file format, USDZ, which is optimized for sharing in various apps while retaining powerful graphics and animation features. Ever since, Sketchfab has been working to bring USDZ support to the platform.

This huge resource will only continue to grow as every new 3D model that is added to the Store or set for free download on Sketchfab will be automatically converted to USDZ. This also makes Sketchfab the easiest way to convert all major 3D file formats to this cutting edge standard.

The primary use for USDz is with AR Quick Look —just tap a link and view a model in AR on your compatible iOS device. In fact, we are working on bringing this exact functionality directly to the Sketchfab viewer soon. In the meantime, the download button on any downloadable model while logged in to Sketchfab, select the USDZ download option to check it out in AR.

    Wow thisi is amazing!! Is this conversion also possible through your API?

    It’s great that you’re finally rolling that functionality out! I would have expected a disclaimer in this post, though, that the chances of a model actually working in AR aren’t 100%:
    – filesize might be too big (anything above 15-20 MB will not work)
    – animation will probably not work, if it does only the first one will
    – your iOS device might run out of memory
    – scaling will most likely be off by some magnitudes (and can’t fully be corrected in AR)
    – postprocessing features of Sketchfab are not supported in USDZ (so some models look vastly different even if they work).

    I tried some examples directly from the first page of your above link, and 1 of 6 worked. 2 of them were 100x too big (so I wasn’t able to scale them down enough), 1 had wrong texture color space (too dark), 1 crashed the iPad with an out of memory message, and 1 just displayed “an error occured”. This is on a high-end iPad Pro 2019.

    Again, I love that you are finally putting that out in the wild, but I’d suggest you explain the above constraints instead of just writing “tap a link and it works!”. 🙂

    Awesome Sketchfab team. The USDZ download capability was well worth the wait. This has reignited my interest in AR. I have also just discovered how Apple AR can now detect people in front of your model, or inside an interior environment, for a more immersive experience.

    Hi Sketchfab,
    With pleasure, I sent you a replay.
    I couldn’t find as far as GLB files. I know the USDZ files from IOS but the other files are also very important for the android. Do you have a converter which converts the USDZ files into GLB?
    Can I see also a summery off al the GLB files on your site?
    many thanks from Holland
    Regards Toine

      yes my question exactly.

      sketchfab is already .gltf based so the .glb should be easy technically!

        Is there a converter to do this? Can we do that on Sketchfab? On the internet it is very difficult for now to find some
