SuperSplat: Edit and Share 3DGS in Your Browser
A guide to SuperSplat - the free web-based editor for viewing, editing, and sharing 3D Gaussian Splatting scenes.
What is SuperSplat?
SuperSplat is a free, web-based editor for 3D Gaussian Splatting (3DGS) scenes. Built by PlayCanvas, it lets you view, edit, and share 3DGS files directly in your browser - no installation required.

Key Features
Browser-Based
No downloads, no installation. Just open supersplat.io and drag in your .ply file.
Works on:
- Desktop (Chrome, Firefox, Safari, Edge)
- Mobile devices (with WebGL support)
- Any operating system
Editing Tools
SuperSplat provides essential editing capabilities:
| Tool | Function |
|---|---|
| Selection | Select Gaussians by region |
| Delete | Remove unwanted artifacts |
| Crop | Define bounding box to keep |
| Transform | Move, rotate, scale the scene |
| Filter | Remove Gaussians by size/opacity |
Compression
One of SuperSplat’s most valuable features is compression. It can significantly reduce file sizes:
| Original | Compressed | Reduction |
|---|---|---|
| 250 MB | 35-40 MB | ~85% |
This makes sharing and web deployment practical.
Sharing
Generate shareable links with one click:
- Public URLs (e.g.,
superspl.at/view?id=xxx) - Embeddable iframes for websites
- Mobile-friendly viewing
Workflow
Basic Editing Workflow
1. Open SuperSplat
2. Drag & drop your .ply file
3. Clean up artifacts (delete floaters, crop edges)
4. Compress for smaller file size
5. Export or shareCleanup Tips
Common issues to fix:
- Floaters - Random Gaussians floating in space (select and delete)
- Ground artifacts - Noise below the main subject (crop with bounding box)
- Edge blur - Fuzzy boundaries (crop tighter)
- Large file size - Use compression before sharing
Export Formats
SuperSplat supports multiple export formats:
| Format | Extension | Best For |
|---|---|---|
| PLY | .ply | Standard format, most compatible |
| Compressed PLY | .ply | Smaller size, web deployment |
| Splat | .splat | Alternative compressed format |
Integration with Other Tools
SuperSplat fits into the 3DGS workflow:
Capture → Training (PostShot) → Editing (SuperSplat) → Display

Compression & CleanupFrom PostShot
- Export .ply from PostShot
- Import into SuperSplat
- Clean up and compress
- Share or embed
For Web Embedding
SuperSplat’s iframe embed is the easiest way to show 3DGS on a website:
<iframe
src="https://superspl.at/view?id=YOUR_ID"
style="width: 100%; height: 500px; border: none;"
allow="fullscreen"
/>Limitations
- Large files - Very large scenes (500MB+) may be slow to load
- Complex edits - No advanced sculpting or painting tools
- Offline - Requires internet connection
- Privacy - Shared links are public by default
Alternatives
| Tool | Type | Comparison |
|---|---|---|
| SuperSplat | Web | Free, easy, great for sharing |
| PostShot | Desktop | Better for training, has built-in viewer |
| Unreal Engine | Desktop | Full game engine integration |
| GaussianSplats3D | Library | Self-hosted web viewer |
Tips & Tricks
1. Compress Before Sharing
Always compress before generating share links. A 250MB file becomes 35MB - much faster to load.
2. Use Selection Tools
Don’t delete manually. Use the selection box to grab large regions of floaters at once.
3. Check on Mobile
Preview your shared link on mobile. Some compression settings look great on desktop but show artifacts on phones.
4. Save Your Work
SuperSplat doesn’t auto-save. Export frequently, especially after major edits.
Getting Started
- Go to SuperSplat Editor
- Drag in any .ply file (try exporting one from PostShot)
- Experiment with the tools
- Hit “Share” to get a public link
Examples

Conclusion
SuperSplat is an essential tool for anyone working with 3DGS. The combination of browser-based convenience, solid editing tools, and easy sharing makes it the go-to choice for cleaning up and distributing 3DGS content.
