No install, runs in your browser
The whole pipeline — upload, detection, 3D generation and the viewer — runs at app.ritn3d.com. There is nothing to download, update or approve through an app store. Open a tab and start.
Now on the web
Convert floor plans to 3D, online
The Ritn3D web app brings the full floor-plan-to-3D workflow to your browser — nothing to download or install. Sign in, upload a floor plan, fine-tune the detected walls, and generate an interactive 3D model you can orbit, walk through, furnish and share. It runs on any modern desktop or laptop, and every project stays in sync with the iOS and Android apps.
How it works
From floor plan to interactive 3D model — entirely in your browser
- Step · 1
Open the web app and upload
Go to app.ritn3d.com and sign in with Google, Apple or email. Drag in a floor plan — JPG, PNG, WebP or PDF — straight from your computer.
- Step · 2
Review the detected walls
Ritn3D detects the walls, doors, windows and rooms. In the browser wall editor you can delete stray walls or add missing ones before generating, so the model is built from a layout you have checked.
- Step · 3
Generate, furnish and share
Generate the 3D model, then orbit it, walk through at eye level, drag in furniture and send a share link. Pro+ users can download GLB and STL files for other 3D and printing tools.
What the web app gives you
The full Ritn3D workflow on a desktop screen, no install required
In-browser wall editor
Before generating, the web app lets you correct the detected layout directly — remove walls the AI over-detected, add ones it missed, and undo as you go. Cleaner walls in means a cleaner 3D model out.
Full interactive 3D viewer
Orbit the finished model, drop into walk-mode to move through it at eye level, and place furniture room by room — all on a full-size screen with mouse and keyboard.
One account, every device
Sign in with the same account you use on iOS or Android. Projects, renders and furniture layouts sync automatically, so you can start on your phone and finish on your laptop.
Share links anyone can open
Every project generates a link that opens the interactive 3D model in any browser — no app, no account. Send it to a client, a partner or a contractor and they explore it instantly.
Export for 3D tools and printing
Pro+ users can download models as GLB files for Blender, Unity, Unreal and other 3D software, or as print-ready STL files for a 3D printer — directly from the web app.

No. The Ritn3D web app runs entirely in your browser at app.ritn3d.com — there is nothing to download or install. Just sign in and upload a floor plan. It works on any modern desktop or laptop browser.
Yes — you can start for free. The Free tier includes a set number of renders each month. Pro and Pro+ unlock more renders, furniture placement, larger share limits and file downloads, and both come with a 7-day free trial.
It is the same Ritn3D account, the same AI pipeline and the same plans. The web app gives you a full desktop screen with mouse and keyboard, plus a browser-based editor for reviewing the detected walls before you generate. Projects sync across the web app and the mobile apps automatically.
Yes. Pro and Pro+ users can drag and drop furniture into the 3D model in the web app, the same way as on mobile — pick pieces from the catalog, arrange them, and walk through the furnished rooms.
Pro+ users can download models as GLB files for use in other 3D software, and as print-ready STL files for 3D printing — directly from the web app. Pro and Free plans use the interactive viewer and share links rather than file downloads.
You can upload JPG, PNG, WebP and PDF floor plans. Digital plans, CAD exports and clean scans of printed architectural drawings all work. Detection is most accurate on clear, high-contrast plans.
The web app runs in any modern browser on desktop and laptop — Chrome, Edge, Safari and Firefox. The interactive 3D viewer uses your device's graphics, so a reasonably recent computer gives the smoothest experience.
