How it works

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.
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.

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.
Refine with markers if needed

If the treatment appears on the wrong window or at the wrong scale, tap a marker on the specific window where it should go and regenerate. Markers help when the room has multiple windows and the AI picks the wrong one.

Tip: Tap the top center of the window frame to anchor the treatment. This tells the AI exactly which window you mean.

Detailed Guides by Scenario

📷

Window Treatment Retailers & Showrooms

Show your curtain, blind, or shade products installed in real room settings without photographing every product in a staged room. Upload your product photos and composite them onto aspirational room scenes for online listings, catalogs, and in-store displays.

Common Scenarios

Custom curtain fabric composited onto living room windows for online store
Roller blinds product photo shown installed on bedroom windows for catalog
Plantation shutters composited onto bay window for showroom display
Sheer drapes shown on floor-to-ceiling windows for e-commerce listing

Best Practices

Use room photos with similar lighting color temperature to your product photos
Choose room angles where the full window and surrounding wall are visible
Specify 'hanging from a rod above the window frame' or 'inside-mounted' for correct placement style
Match the room style to your product — modern rooms for minimalist blinds, traditional rooms for heavy drapes

Curtain panels on living room windows for online store listing

place these curtain panels from the reference onto both living room windows, hanging from a rod just above the frame, with natural fabric draping and folds matching the warm afternoon light

Roller blinds on bedroom window for product catalog

composite these roller blinds from the reference onto the bedroom window, mounted inside the frame, half-lowered to show both the blind material and the window, matching the soft daylight

📷

Interior Design Client Presentations

Show clients exactly how specific window treatments will look in their actual rooms. Upload the client's room photo and composite the treatments you're recommending. Faster than CAD renderings, more convincing than fabric swatches held up against a window.

Common Scenarios

Recommended drapery composited onto client's living room windows for design pitch
Multiple blind options shown on the same client window for comparison
Custom valance and curtain combination previewed in client's dining room
Layered treatment — sheers plus drapes — visualized on client's bedroom windows

Best Practices

Use the client's actual room photos for maximum impact in presentations
Create multiple versions showing different treatment options on the same windows for comparison
Include 'with natural fabric weight and draping' for realistic soft treatments
For layered looks, composite one layer at a time — sheers first, then drapes over them

Linen drapes in client dining room for design proposal

place these linen drapes from the reference on the client's dining room windows, pooling slightly on the floor, with natural fabric texture and folds matching the overhead chandelier light

Roman shades on kitchen windows for client comparison

composite these Roman shades from the reference onto the three kitchen windows, each shade at a slightly different height, with consistent fabric pattern alignment across all three

📷

Home Renovation Planning

Preview how new window treatments will look in your own rooms before buying. Upload a photo of your room and composite the exact product you're considering. Eliminate guesswork on color, scale, and style before spending hundreds on custom treatments.

Common Scenarios

Previewing curtains from Pottery Barn in your living room before ordering
Testing blackout roller blinds on bedroom windows before committing to install
Comparing two different shade fabrics in your home office window
Visualizing floor-length drapes vs cafe curtains on kitchen windows

Best Practices

Photograph your room in natural daylight for the most accurate color matching
Use the product photo from the retailer's website as your reference image
Try the same treatment at different heights: 'ceiling-mounted' vs 'just above frame'
Save each version to compare side-by-side before purchasing

Previewing blackout blinds in bedroom before purchase

place these blackout roller blinds from the reference on my bedroom windows, mounted inside the window frame, fully lowered, matching the room's warm evening lamp light

Visualizing velvet curtains in living room before ordering

composite these velvet curtains from the reference onto the living room window, hanging from ceiling to floor with rings on a rod, with natural heavy fabric draping

If something looks off

Window treatment scale doesn't match the window

Why: The AI misjudged the relative proportions between your product photo and the room windows, making the treatment too wide, too narrow, or the wrong length.

Try:

place the window treatment at correct scale to fill the window width, with floor-length panels reaching just above the baseboard

Try This →

Tip: Include real dimensions: 'these are 84-inch panels on a 48-inch-wide window' to anchor the scale correctly.

Treatment appears flat and painted on instead of hanging naturally

Why: The composite lacks fabric physics — no folds, no draping, no weight. The product photo may have been too flat or stiff.

Try: composite the curtains with natural fabric weight, soft folds, and gentle draping as if hanging from a rod under gravity

Try This →

Tip: Add 'with visible fabric folds and natural draping weight' to every curtain prompt. For blinds, use 'with visible slat depth and shadow between slats.'

Lighting on the treatment doesn't match the room

Why: The product was photographed under different lighting than the room, creating an obvious color temperature or shadow direction mismatch.

Try:

composite the treatment matching the room's lighting direction and color temperature — warm daylight from the windows on the left

Try This →

Tip: Describe the room's light source: 'warm afternoon sun from the right' or 'cool overhead fluorescent.' This helps the AI relight the treatment.

Treatment appears on the wrong window

Why: The room has multiple windows and the AI couldn't determine which one you meant from the description alone.

Try: Tap a marker on the specific window where you want the treatment placed, then regenerate with the same prompt

Try This →

Tip: Markers tell the AI 'I mean THIS window specifically.' Essential for rooms with more than two windows.

AI changed the wrong area or something I didn't want changed

Why: The AI couldn't determine exactly which area you meant from description alone. This happens with ambiguous requests or rooms with multiple potential placement areas.

Try: Tap a marker on the specific area you want to change, then regenerate with the same prompt

Try This →

Tip: Markers tell the AI 'I mean THIS one specifically.' Use them when description alone is ambiguous.

Edges where treatment meets window frame look harsh

Why: The boundary between the composited treatment and the window frame shows visible hard edges or color halos, breaking the realism.

Try:

blend the treatment edges seamlessly into the window frame area, with soft natural transitions where fabric meets wall and frame

Try This →

Tip: Try 'with feathered edges where the curtain rod meets the wall' for cleaner top-line transitions. Harsh edges are most visible at the mounting point.

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. Use markers only when the room has multiple windows and the AI keeps picking the wrong one.

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.
