# AI sky replacement URL: https://dreambench.ai/tools/ai-sky-replacement A preset of the [AI image editor](https://dreambench.ai/tools/ai-image-editor): the same engine, set up for this one job. Pick a new sky and the one in your photo is swapped for it: clear blue, a golden sunset, dramatic clouds, soft overcast, a starry night or a pastel dawn. Everything below the skyline stays as it is, and the light and reflections on the scene are matched to the new sky. ## What is AI sky replacement? It swaps the sky in a photo for a new one, clear blue, a sunset, clouds, overcast, stars or dawn, and matches the light on the scene to it, keeping everything below the skyline. It is for property, wedding, landscape and travel photos taken on a gray day. It is part of every DreamBench plan, from $9.99 a month. ## How to change the sky in a photo 1. Upload a photo: A landscape, a street, a house for sale, a wedding group under a flat white sky: anything with sky in the frame. 2. Pick the new sky: Clear blue, golden sunset, dramatic clouds, soft overcast, starry night or pastel dawn. Add a note if something matters: keep the sun on the left. Then press Make the edit. The first time, create a free account and choose a plan. 3. Download the photo: The sky is replaced and the light on the scene is matched to it, ready to download full size. **Choices.** - New sky: Clear blue, Golden sunset, Dramatic clouds, Soft overcast, Starry night, Pastel dawn - Anything else: an optional note (up to 160 characters) ## Replace the sky in real estate photos A house photographed under a flat white sky, given the clear blue it has on a good day. Everything below the roofline is instructed to stay as shot. Each run draws its own clouds, so a set of exterior photos gets skies of one kind, not one identical sky. Choose a sky the place could have had, keep the original, and check what your listing site and your board allow for edited photos; some ask for them to be labeled. ## Replace a gray sky with a sunset A wedding, a portrait or a beach day under cloud, given the warm light of golden hour, with the highlights and shadows on the scene warmed to match. Photos taken in soft, even light take a sunset best; hard midday shadows below it still read as midday. ## Fix an overexposed white sky A landscape whose sky came out pure white because the camera exposed for the ground. A blown-out sky holds nothing to recover, so a new one is drawn: clear blue or dramatic clouds for the view you remember. ## Add a starry night sky to a photo A photo taken at dusk or after dark whose sky came out muddy, black or orange with street light, given a clear sky full of stars and a faint Milky Way. Over a scene shot in daylight, stars read as a composite, because the light below is still the day's; dawn or sunset keeps it believable. ## Works with - What it takes: JPEG, PNG, WebP or HEIC, up to 40 MB, straight from a phone or a camera. An iPhone's HEIC photo becomes a JPEG on your device as you choose it, in any browser. A picture larger than 2048 pixels on its long edge is scaled to 2048 before the run. - What you get: A JPEG in your photo's proportions. - Zillow, Rightmove and other listing sites: The JPEG keeps your photo's proportions; upload it as you would the original. - Lightroom and Photoshop: Open the result for any grading by hand. It arrives as one flattened picture, with no sky layer or mask. - Instagram and photo books: Post or print it at the shape you shot it; check fine edges at full size before printing large. - The DreamBench composer: Animate the new sky opens the photo as the reference for a short clip, the clouds moving. ## Which model runs it, and where it fails The AI sky replacement runs on [GPT Image 2.5](https://dreambench.ai/models/gpt-image-2.5). GPT Image 2.5 Flare is the smaller of OpenAI's two GPT Image 2.5 models, built for high-quality everyday images. It takes your photo and an instruction and draws the picture again. It declines some photos under OpenAI's content rules, photos of real people among them. A run the model declines under its content rules is refunded. - Six skies that get asked for: Clear blue for a listing, golden sunset for a portrait, dramatic clouds for a landscape, soft overcast for even light, a starry night for a scene shot after dark, a pastel dawn for something quieter. - The ground stays the ground: The instruction keeps everything below the skyline as it is: buildings, land, water, people and objects, in the same framing. It is a re-render rather than a pixel-exact copy, so check fine detail in the page. The photo is read at no more than 1536 pixels on its long edge, so a sharp original matters more than a large one. - Light to match: The light, color and reflections on the scene are adjusted to the new sky, so a sunset warms the walls and a blue sky cools the shadows, instead of the sky sitting behind the scene like a backdrop. **Where it fails.** - Sky seen through fine branches, hair, railings or wires is the hardest edge: it can soften or fill in. - Reflections in water are matched approximately, not traced, so a mirror-calm lake may not show the new clouds. - A new sky doesn't move the sun: hard daylight shadows below a sunset or a night sky read as a composite. - The whole picture is drawn again, so small text and fine detail below the skyline can drift slightly. ## AI sky replacement FAQ - **How do I change the sky in a photo?** To change the sky in a photo, upload it, pick clear blue, golden sunset, dramatic clouds, soft overcast, starry night or pastel dawn, and press Make the edit. Everything above the skyline is replaced and the light, color and reflections on the scene are matched to the new sky. Make the edit with any DreamBench plan and download it full size. - **Can I use the AI sky replacement without a plan?** No. Every run needs a DreamBench plan; you create an account on the way, and the button shows the price in credits before you press it, which depends on the size of the photo. A run that fails is refunded, and so is a photo both models decline under their content rules. - **Does it work on photos with people in them?** Yes. The first model declines some photos of real people under its content rules; a photo it declines is tried once on a second model, on the same payment. Only when both decline is the run refunded. - **Can I use my own sky photo?** No. You pick one of the six skies and can add a short note, such as keeping the sun on the left. To place a sky photo of your own on layers you can adjust, an editor with sky replacement, such as Photoshop or Luminar Neo, does that. - **Will sky replacement affect my photo's quality, and what size is the result?** The picture is drawn again with the new sky, in the same framing and proportions, as a JPEG of about 1.4 megapixels, so a large photo comes back smaller than it went in. Fine detail below the skyline, small text or thin branches, can drift slightly, so compare the result with your original at full size. - **Can I replace the sky in Photoshop or on my iPhone instead?** On a computer, yes: Photoshop's Sky Replacement command swaps the sky for a preset or your own photo and adjusts the foreground's color, and Luminar Neo's Sky AI does the same. The Photos app on an iPhone has no sky replacement. This page does it in the browser on a phone, a tablet or a computer, nothing to install, with six skies, and matches the light on the scene. - **Does sky replacement work with trees, hair and fine edges?** It is the hardest part of the job. Sky seen through fine branches, hair, railings or wires is where the edge can soften or fill in, because the new sky has to be drawn around every gap. A clean skyline, a roofline or a hill, replaces almost invisibly. Check those edges in the page before you download. - **Why does a replaced sky look fake?** Usually the light: hard midday shadows under a sunset or a night sky, or reflections still showing the old sky. Pick a sky that suits the light already in the photo, a sunset for soft even light and a clear blue for a bright day, and check water and windows in the result before you use it. - **Do I have to disclose a replaced sky in a property listing?** Rules vary by listing portal and by board, and some ask for edited or AI-altered photos to be labeled, so read yours before you upload. Keep the original, choose a sky that is typical for the place rather than a dramatic one, and label the photo where your board asks; a replaced sky changes the weather, not the property. - **Is the result marked as AI-made or watermarked?** There is no visible mark, and DreamBench adds no watermark of its own. The model that makes the edit may embed an invisible mark or metadata that identifies the picture as AI-generated; it doesn't show in the picture. The model section on this page names the models the run uses and links their pages. - **Can I do a whole set of listing photos at once?** No. Each run takes one photo, and there is no batch upload or API: the tool is used through this page. Pick the same sky for every exterior and the set comes back with skies of one kind, each run drawing its own clouds, so they match in kind rather than pixel for pixel. - **Will the water in my photo reflect the new sky?** Approximately. The instruction asks for the new sky's color and reflections to be matched on the scene, so a lake under a sunset picks up warm tones. It is an estimate rather than an optical reflection: a mirror-calm lake may not show the exact cloud shapes. Rippled water hides the difference. - **Can it replace the sky in a video?** No. It replaces the sky in one still photo; a video's sky has to be tracked through every frame, which this tool doesn't do. To see the new sky move, press Animate the new sky: the photo opens in the composer as the reference for a short clip with the clouds drifting. - **What can I write in the Anything else box?** The Anything else box takes a short note of up to 160 characters, added after the sky instruction: keep the sun on the left, no clouds at all. The instruction also tells the model to keep everything in front of the sky as it is, so a note about the sky and its light works, while one asking for a new background fights it. - **Can I get the replaced sky at full resolution for a print or a listing?** Not from the run itself: the photo is read at no more than 1536 pixels on its long edge and the result is drawn at about 1.4 megapixels in its proportions, so a 12-megapixel photo comes back at about 1360 by 1024 pixels. For a print or a listing that wants more, run the result through the AI image upscaler, up to 4096 pixels on its long edge. - **How much does the AI sky replacement cost?** A run starts at 13 credits from your DreamBench plan, depending on the photo, and once you have a plan the button shows each run's price before you press it. Starter, $9.99 a month, includes 1,100 credits a month, at least 57 runs of the AI sky replacement, plus AI video. A run that fails is refunded. - **Do I need an account to use the AI sky replacement?** Yes: a free account and a DreamBench plan. The tools are part of every plan, from Starter at $9.99 a month. - **Which image files does the AI sky replacement take?** A photo up to 40 megabytes: JPEG, PNG, WebP, HEIC or another format your browser opens. A photo straight from a phone is fine, an iPhone's HEIC included: the page scales a large picture down to 2048 pixels on its long edge before the run, so the result is never larger than the page says. - **Can I use what the AI sky replacement makes commercially?** Yes. Under the DreamBench Terms you may use what a tool makes for personal and commercial purposes, including advertising, monetized content and work for clients, with no separate commercial-use upgrade. The Terms don't guarantee copyright in a result or clear another person's rights in your upload, so only use photos you have the rights to. - **Is my photo used to train AI?** No. DreamBench doesn't use your prompts, uploads or videos to train or fine-tune AI models, and any future training program would be opt-in. - **What happens to my uploaded photo?** It stays in your browser until you make a result. Then it is used to make that result and nothing else, and removed from the tool's storage after seven days along with the result. A result you keep in your library stays as long as you keep it. Runs on GPT Image 2.5. DreamBench is an independent platform; its tools come with every plan (https://dreambench.ai/pricing). Copy last checked 2026-10-22.
