Needle Cloud

Manage and optimize 3D files
and host your spatial web apps.


Magically optimized

Upload a 3D file and get a web-ready version automatically — a fraction of the size, loading in a fraction of the time, on any device.

  • Right-sized for every device. We build lighter levels of detail for meshes and textures and load them only when needed — fast on phones, crisp on desktops.
  • Presets for any project. Pick hero quality for a product showcase, or lighter settings for props in a large scene.
  • No manual work. No remeshing, no exporting variants by hand — it all happens automatically.

Your 3D files,
ready for the web.

Upload your 3D assets in a variety of formats, including GLTF, USD, FBX and VRM . We prepare them for various usecases using our state-of-the-art optimization pipeline.

You can embed them in your website, share links with others, or download them for further use.

Here are some examples:

Ultra-fast HDR environments

Realistic image-based lighting that loads in a fraction of the time. FastHDR environment maps load up to 10× faster than EXR, use around 95% less graphics memory, and stream in smoothly without freezing your scene — all built on open standards.

Browse 20+ ready-to-use environments in 1k, 2k and 4k, and drop them straight into your three.js or Needle Engine project — or compress your own EXR or HDRi images on Needle Cloud.

Up to 10× faster to load an environment
Shorter is better – example used 4K textures
Around 95% less graphics memory used
Shorter is better – example used 4K textures
Up to 8K sharper, just as fast

The time you save with FastHDR goes straight back into image quality. A crisp 4K environment now loads as quickly as a low-resolution one used to — so even ultra-detailed 8K scenes become practical on the web, without slowing your project down.
