What is a room visualizer?

A room visualizer is a tool that shows how changes look inside a photo of your actual room, such as new furniture, a rug, or wall decor, before you commit to them.

The emphasis is on the whole space and its context. A room visualizer keeps your existing walls, windows, floor, and light in the frame, then adds something new on top, so you judge the change against everything already there rather than on a blank background. That context is what makes the preview trustworthy.

It overlaps with a furniture visualizer, which centers on a single product, but the framing is broader: the room and how a piece sits within it. DecorViz does this from a photo of your room and an image of whatever you are adding, and shows the result at a realistic size and proportion rather than exact measurements.
