From installing the extension to your first texture set, upscale and conversion. Short chapters, no jargon.
Grab3D runs in Chrome and other Chromium browsers that support Chrome extensions (Edge, Brave, Arc, Opera).
Click the puzzle icon next to the address bar and press the pin beside Grab3D. The faceted G now sits in your toolbar, one click away on every model page.
Every PBR model ships with texture maps: base colour, normal, metallic-roughness and sometimes AO or emissive. Use Textures in the popup to download all of them at once as PNG images. A full texture set counts as one download on the Free plan.
Open Upscaler from the popup, load a model or a set of maps and choose 4K or 8K. Grab3D resizes base colour, normal, metallic/roughness, AO and emissive maps with standard resampling. It is not AI enhancement: it gives you the resolution your tool expects without inventing detail.
Open Converter from the popup and load GLB, GLTF, OBJ, FBX, 3MF or STL files, including textures and companion files such as .mtl. Choose the target format and save.
Click Workspace in the Grab3D popup to open the free 3D Lab. Drop in a GLB, OBJ, STL, FBX or 3MF file and check it in texture, clay, wireframe, normals or point cloud view. It is free on every plan.
One license works on up to 2 devices. Switching computers? Release the old device from the popup under Manage plan to free its slot, then activate on the new one.
Refresh the model page and wait until the model has fully loaded before opening the popup. Still missing? Re-export the model in Meshy or Tripo, refresh, and try again.
Free includes 3 models, 15 texture PNGs and 1 Community model per month, reset on the 1st of every month (UTC). Upgrade for unlimited downloads.
