Adding 3D to a web page can make a product easier to understand, but a heavy model slows the page down. Here is how to keep AI-generated models light.
1. Check the file size first
Models downloaded from 3DView.ai are GLB files. Look at their size before publishing: a few megabytes loads comfortably on a phone, tens of megabytes will not.
2. Reduce the polygon count
AI generators often produce dense meshes. In Blender, the Decimate modifier lowers the polygon count while keeping the silhouette; compare the result with the original before you replace it.
3. Compress the textures
Textures are often the heaviest part of a GLB. Resizing them to what the page actually shows (for example 1024 or 2048 pixels) and storing them as JPEG or WebP saves a lot. The free command-line tool glTF Transform can do this in one step.
4. Compress the geometry
Draco and Meshopt compress the geometry of glTF files; glTF Transform supports both, and Blender's glTF exporter supports Draco. Make sure your viewer can decode the format you choose (Google's model-viewer supports Draco).
5. Load it only when needed
Show a poster image first and load the model lazily, so the 3D file does not delay the rest of the page. model-viewer supports both a poster image and lazy loading.
SEO impact
Google uses Core Web Vitals as part of its page experience signals, so a 3D element that delays the page can work against you. Keep the model off the critical loading path.
