Floorplan 3D converts a 2D floor plan into a real 3D home you can furnish and walk through. You give it the plan you already have — the one from a property listing, a developer's brochure, a scan — mark the rooms once, set the scale with two clicks, and the converter builds the walls, doors and windows for you. The result is not a static picture: it opens in the full editor, where every wall and piece of furniture stays movable.

What kind of 2D plan do you have?
- An estate-agent or listing plan. The most common case. These are drawn to scale and usually carry a printed dimension — perfect for calibrating. A screenshot is fine; crop away the listing text around it if you can.
- A developer's or architect's PDF. Opens directly in the converter, with a page picker for multi-page files. Vector PDFs render crisply, which makes the room edges easy to follow.
- A scanned blueprint. Works as long as the walls are legible. Straighten a tilted scan first if the rooms look skewed — the converter traces what it sees.
- A photo of a hand-drawn sketch. Surprisingly workable. Shoot it straight-on in good light, trace along your drawn walls, and calibrate with the one measurement you actually know, like the width of the house.
- No file at all? Start from a blank canvas, or open one of the ready-made layouts — a studio, a 1-bedroom or a 2-bedroom plan — and reshape it into yours.
Two ways to convert: trace it, or let AI draft it
| Manual tracing | AI room detection | |
|---|---|---|
| How it works | You drag one rectangle over each room, on top of your plan, and label it. | AI finds the rooms, doors and windows and drafts the rectangles; a second pass re-checks the draft against your plan. You then drag corners to correct anything it got wrong. |
| Cost | Always free, unlimited. | Free on the site — a few runs a day per visitor, no key needed. Or bring your own AI provider key for unlimited runs. |
| Best for | Small plans, crooked photos, or when you want exact control over every wall. | Clean, modern plans with many rooms, where tracing by hand would take a while. |
| Watch out for | It takes a few minutes of clicking. | It is a draft, not gospel: small rooms and L-shaped rooms are the ones to double-check before converting. |
Either way, you calibrate the scale the same way: click the two ends of a distance you know and type it — millimetres, centimetres, metres, inches and feet are all accepted. Calibrate on the longest printed dimension; small clicking errors then matter least.
What you get after converting
- A real 3D home, not an image. Walls, doors and windows are generated from your rooms; orbit it, view it from above, or take the first-person walkthrough, with day and night lighting.
- The full editor. Move walls, resize rooms, flip a door's swing, remove a window. Room areas are computed live, and flooring comes with a cost estimate.
- Furniture that fits your rooms. A 70-piece library; every piece can be resized to its real width and depth, and its height scaled from 30% to 300% — so the sofa in the plan is the sofa you actually own.
- Ways to share and save. Copy a share link that restores the exact plan and furniture for whoever opens it, or export the plan as PNG or JSON.
- A way back. The editor's File menu can send the plan back to this converter as rectangles, so fixing a wall never means starting over.
Honest limits
- One floor per plan. Two-storey houses convert floor by floor, as separate plans; stacked floors in a single 3D model aren't supported yet.
- Tiny listing thumbnails struggle. If the plan is a 300-pixel thumbnail with unreadable walls, tracing gets guessy. A larger export or the PDF version converts far better.
- The AI draft needs your eyes. Detection is good at finding rooms on clean plans, weaker on cramped small rooms and hand-drawn lines. The correction pass — dragging corners — is part of the workflow, not a failure of it.
Common questions
Is the 2D to 3D converter really free?
Yes. Uploading, tracing, AI room detection (a few free runs per day), converting, editing, furnishing and sharing are all free, with no account and no watermark. If you prefer, you can also bring your own AI provider key for unlimited detection runs.
Which file formats can I convert?
PNG and JPG images — estate-agent plans, listing screenshots, scanned blueprints, photos of hand-drawn sketches — and PDF floor plans. For a multi-page PDF you pick the page that shows the plan before tracing.
What happens to the floor plan I upload?
Manual tracing and conversion happen entirely in your own browser; the file never leaves your device. If you use the AI detection, the image is sent once to the AI provider through the site's proxy so the rooms can be detected, and the result comes back as room rectangles. Your finished design is stored only in your browser's local storage.
Can I edit the plan after converting it to 3D?
Yes — the result is a fully editable plan, not a picture. Move walls in the editor, resize rooms, flip or remove doors and windows, add furniture and change flooring. You can also send the plan back to the converter from the editor's File menu, adjust the room rectangles, and convert again.
Can I convert a two-storey house?
Convert one floor at a time. The editor works on a single floor per plan, so for a two-storey house you would convert the ground floor and the upper floor as two separate plans. Stacked floors that share one 3D model are not supported yet.
