What is this tool?
Floorplan 3D is a home layout design tool that lives in a single web page. You arrange furniture on a 2D floor plan, edit walls and measure rooms, then switch to a full 3D view of the same home — bird's-eye, angled, or a first-person walkthrough. There is nothing to install and no account to create: the editor opens in your browser and your design is stored locally in your browser, not on our servers.
Main features
- 2D floor plan editing at true scale, with dimensions in millimetres or feet/inches (one-click unit switch)
- A library of 70 furniture and appliance items you can drag, rotate and resize
- Edit non-load-bearing walls, with load-bearing walls clearly marked
- One-click 3D scene: multiple viewing angles, room fly-to, and a first-person walkthrough mode (WASD + mouse on desktop, virtual joystick on touch screens)
- Daylight slider and night lighting, full-height or cutaway walls
- Automatic room-area and usable-area calculation, plus flooring material cost estimates
- Export your design as a PNG image, or export/import it as JSON
- 2D floor plan to 3D converter: upload a floor plan image or PDF (or start from a blank canvas), trace the rooms, adjust the auto-generated doors and windows, and turn it into an editable 3D plan — then share it with a link. Preset starter plans (studio, 1-bedroom, 2-bedroom) are included; see the step-by-step guide
- Interface available in English, Simplified Chinese and Traditional Chinese

Frequently asked questions
Is Floorplan 3D free?
Yes. The editor, the 2D-to-3D converter, furnishing, measurements and plan sharing are all free, with no account and no watermark. The only optional cost anywhere is AI room detection in the converter, which uses your own AI provider key — any fee is charged by that provider to you.
Do I need to install anything or create an account?
No. Floorplan 3D is a web app: open the page and start designing. Your work is saved automatically in your own browser.
Where is my design stored?
Only in your browser's local storage, on your device. Nothing is uploaded to our servers — there are no user accounts or server-side storage at all. Share links encode the plan inside the link itself.
