3DRoomDesign.ai converts 2D floor plans into browser-based 3D room designs without CAD software. Users can upload PDFs, JPGs, PNGs, blueprints, room photos, rough measurement files, or hand-drawn sketches. The AI reads walls, doors, and spatial relationships, then builds a proportioned 3D room with furniture, finishes, lighting, and decor layers, usually in under 10 minutes. Designs can be adjusted live by changing materials, wall colors, flooring, natural lighting, and furniture positions. Each project can be shared with clients through one link, allowing them to rotate, zoom, walk through, and review details without downloading an app or signing up. Users can also export high-resolution renders, dimensioned floor plans, material specifications, estimates, and formatted PDF proposals.
