Upload Your Design
What to upload to Render a House, which image, PDF, and 3D formats work best, how to upload SketchUp files directly, and how to export from other tools.
Render a House accepts two kinds of input: images (sketches, drawings, photos, screenshots) and 3D models (SketchUp SKP, GLB, GLTF, OBJ, STL).
The upload screen

Before uploading, set:
-
Save to — pick a folder, create a new one (via New Folder...), or leave as "No folder"

-
Project name — optional. Leave blank and Render a House will generate a name based on what it sees in your image
Three ways to add a file:
-
Drag and drop onto the drop zone

-
Click to upload to open the file picker

-
Sample images — scroll down the upload screen to use one of the example drawings
Supported formats
| Kind | Formats |
|---|---|
| Image | PNG, JPEG, WebP |
| 3D model | SKP, GLB, GLTF, OBJ, STL |
Max file size for images: 5 MB. 3D models have no size limit.
3D import is a paid-plan feature.
Recommended dimensions: 2000–3000 px on the longest side.
See Supported File Formats for the full breakdown.
Tips for best results
For image uploads
- Clean, high-contrast drawings work best. A crisp export from your design tool beats a blurry phone picture every time
- Crop tight. Whitespace and clutter confuse the AI. Leave a small margin around the building
- Include context when it matters. To anchor a tree line, street, or cliff, show some of it in the drawing
- Use a 3D screenshot with a neutral sky and flat lighting when exporting from SketchUp, Rhino, or 3ds Max. Avoid depth-of-field and motion blur
For 3D model uploads
- SketchUp users can upload the
.skpdirectly. For other tools, GLB is the recommended format — GLTF and OBJ also work. Blender, Rhino, and others can all export to GLB - Keep the file under ~100k polygons. 3D models have no file-size limit, but very dense meshes can slow the upload — decimate if needed
How to export from your design software
From the upload screen, click How to export from your design software for step-by-step instructions. Most common tools:
- Sketchup — no export needed, upload the
.skpfile directly - Rhino / Blender — native
.glbexport
For anything else, export a clean view as a JPEG or PNG — it's the simplest path and works with any design software.
What happens after upload
- Render a House processes your file and creates a view
- You land in the editor to configure render settings and generate your first render
- The original upload stays attached to the view forever — you can always re-render with different settings or add new views to the same project
Troubleshooting
"File too large" — images over 5 MB. Resize the image or take a screenshot at 2000–2500 px. 3D models have no size limit
Upload hangs — first, make sure your internet connection is working. Then try refreshing the page, a different browser, or incognito mode. Check you're not on a VPN. If it still fails, rename the file using only letters and numbers (no spaces or special characters)
Upload succeeds but the result ignores my drawing — the drawing is likely too low-contrast, too small, or has too much background. Crop tighter and upload a cleaner version
