Browser-Based Projection Mapping — No Install, No Limits
4mapper is a free browser-based projection mapping tool that runs entirely in Chrome or Edge. No software to download. No dongle. No proprietary hardware. Just open a tab and start building your first mapped scene.
Why browser-based?
- Start immediately — no install process.
- Access your projects from any desktop machine.
- No license files or hardware keys required.
- Same workflow on Windows, Mac and Linux.
- Regular updates without manual reinstalls.
How browser-based projection mapping works
4mapper uses modern browser APIs to handle media loading, quad surface creation and real-time mapping output. Your content stays in your project — you upload videos, GIFs or images, place them onto defined surfaces and switch between scenes during your performance or installation.
The mapping engine runs locally inside the browser tab once your project is loaded, so it stays responsive even during a live performance.
2. Create quad surfaces
Define and position projection surfaces in the editor and align them to your physical target — a wall, a building face, a prop or any shaped object.
3. Build scenes and play
Organize surfaces into scenes and trigger them from the browser during your show. No external software needed at runtime.

Is browser-based projection mapping reliable for professional use?
4mapper uses modern browser APIs to handle media playback, surface warping and scene management. It is suitable for professional installations and live events.
Which browsers are supported?
Chrome and Edge on desktop are fully supported. The tool is designed for desktop use on Windows, macOS and Linux.
Can I use it offline?
Once your project and media files are loaded, the mapping engine runs locally in your browser. An internet connection is needed only for the initial load and media uploads.
How does it compare to desktop projection mapping software?
Browser-based tools like 4mapper are faster to start and easier to access from different machines. Desktop tools may offer more advanced rendering, but often require installation and licensing that add complexity.
