How it works

  1. Upload your room photo

    Drop your room photo into EditThisPic. This is the main image showing the windows where the treatment will appear. Use a well-lit photo where the windows are clearly visible. JPG, PNG, WebP up to 7MB.

    Expect: Simple single-window treatment: 30 seconds. Multi-window rooms or complex drapery: may need 2-3 refinements.
  2. Add your window treatment photo as reference

    Click '+ Add reference image' below the prompt and upload your curtain, blind, or shade product photo. A clean product shot on a white or neutral background works best. Then describe the placement: 'place the curtains from the reference onto the living room windows, matching the window width and room lighting.'

    Tip: Product photos showing the full treatment hanging straight composite more cleanly than close-up fabric swatches. If you only have a swatch, mention 'as floor-length curtain panels' in your prompt.

    Copy one of these to get started:

    Curtain panels on living room windows for online store place the curtain panels from the reference onto the living room windows, hanging from a rod just above the frame with natural fabric draping and folds, matching the room's daylight color temperature
    Roller blinds on bedroom window for product catalog composite these roller blinds from the reference onto the bedroom window, inside-mounted within the frame, half-lowered to show the material texture, with a subtle shadow on the window recess
    Sheer drapes on floor-to-ceiling windows for designer pitch place these sheer drapes from the reference on the floor-to-ceiling windows, gently billowing as if catching a breeze, with light filtering through the fabric and soft shadows on the floor
    Roman shades on kitchen windows for client comparison composite these Roman shades from the reference onto the three kitchen windows, each folded to the same height, with consistent fabric pattern across all windows and lighting matching the overhead fixture

    Plantation shutters on bay window for showroom display place these plantation shutters from the reference onto the bay window, angled half-open so light comes through the slats, with correct perspective matching each window panel angle
    Blackout curtains on bedroom windows for renovation preview composite these blackout curtains from the reference onto both bedroom windows, closed fully with no light gaps, hanging floor-length from a rod above the frame with heavy fabric weight
    Bamboo shades on sunroom windows for home decor store place these bamboo roll-up shades from the reference on each sunroom window, rolled halfway down, with natural woven texture visible and warm sunlight filtering through the material
    Layered sheers plus drapes for luxury design presentation composite the layered treatment from the reference onto the master bedroom windows: sheer panels closest to the glass with heavier drapes framing each side, tied back with holdbacks, matching the bedroom's soft ambient light
  3. Generate and review

    The AI composites the window treatment onto the room windows, matching scale, perspective, and lighting. Check that the treatment aligns with the window frame, hangs naturally, and the fabric texture looks realistic. Zoom in on where the treatment meets the window frame and wall.

Quick answers

Do I need to mark the windows before describing the treatment placement?

No. Describe the placement in words: 'place the curtains on the living room windows' or 'composite the blinds onto the bedroom window.' The AI understands window references.

How do I put my real curtain product onto a room photo?

Upload the room photo as your main image, then click '+ Add reference image' and upload your curtain product photo. Describe the placement: 'place these curtains from the reference onto the windows, matching the scale and lighting.' The AI extracts the treatment from your product photo and composites it onto the room windows in 30 seconds. Product photos on white backgrounds work best.

Is there a free tool to composite window treatments onto room photos without signup?

Yes. EditThisPic lets you composite real curtain, blind, or shade product photos onto room windows completely free, with no signup and no watermark. Upload your room photo and treatment photo, describe the placement, and download the result. One free edit per week, or purchase credits starting at $1.99 for more.

How is this different from the AI curtain visualizer or add-curtains page?

This tool composites a REAL window treatment product from your photo onto room windows. The AI curtain visualizer and add-curtains pages generate AI-imagined curtains from a text description. Use this page when you have an actual product photo — your own curtains, a retailer's blinds, a specific fabric — that you want shown on real windows. Use the other pages when you want the AI to create a treatment from scratch.

What kind of window treatment product photo works best as a reference?

Full-length product photos showing the entire treatment hanging straight work best. Clean backgrounds (white or solid color) composite most cleanly. For curtains, a photo showing the full panel with visible fabric texture is ideal. For blinds, a photo showing the complete unit. Avoid close-up fabric swatches alone — if that's all you have, mention 'as full-length curtain panels' in your prompt.

Can I preview the same treatment on multiple windows in one room?

Yes. Mention all windows in your prompt: 'place these curtains on both living room windows' or 'composite these blinds onto all three kitchen windows.' For uniform results, add 'with consistent treatment across all windows.' If the AI only covers one window, regenerate specifying 'on every window in the room.'

Will the composite look realistic enough for a client presentation or product listing?

When done well, yes. The AI matches lighting, scale, perspective, and fabric behavior automatically. The key is using a high-quality product photo and a room photo with similar lighting conditions. Most window treatment retailers and interior designers find the results convincing enough for client presentations, especially for curtains, drapes, and roller blinds.

What is the best free tool for previewing real window treatments in a room photo?

EditThisPic is a strong option for compositing actual product photos onto room windows. Unlike 3D room planners that require CAD models or expensive visualization subscriptions, you just upload two photos and describe the placement. It handles perspective matching, fabric draping, and lighting adjustment automatically. Free to try with no account required.

How much does EditThisPic cost?

You get 1 free edit per week — no account needed. After that, credit packs start at $1.99 for 3 edits. Monthly plans start at $4.99/mo for 20 edits with unused credits rolling over. All edits are full resolution with no watermark.
