How it works
How to generate images from images in three steps
No layers, no masks, no learning curve. Describe the outcome and let the model do the work.
Describe the change with a prompt
Say what should be different: a new background, a different style, other lighting, a cleaner composition. Plain language is enough.
Generate, preview and download
The model keeps what you did not mention and changes what you did. Download the result or keep iterating inside Krater.
Before and after
Image to image AI examples with the exact prompts
Every pair below was created on Krater from the image on the left with the prompt shown underneath. Copy a prompt, upload your own photo and adapt it.
Studio product shot
Prompt: Turn this into a clean studio product photo on a pure white background with soft, even lighting and a subtle reflection
Restage an interior
Prompt: Keep the room and architecture exactly the same, repaint the walls warm terracotta, add a low wooden bench with linen cushions and warm golden hour sunlight
Photo to watercolor
Prompt: Repaint this image as a soft watercolor illustration on textured paper, keep the composition and subject the same
Headshot polish
Prompt: Remove the crystal helmet and turn this into a professional corporate headshot with a neutral blurred grey studio background and flattering soft light
Blueprint to photo
Prompt: Turn this blueprint into a photorealistic photograph of the same sailing ship on the open ocean at sunset, dramatic sky
3D clay render
Prompt: Turn this into a polished 3D rendered version with smooth clay materials, pastel mint background and studio lighting
AI image generator from image
What an image to image AI generator does
An image to image AI generator starts from a picture you already have instead of a blank canvas. You upload a photo, sketch, screenshot or render, add a short prompt, and the model produces a new version that keeps the parts you did not mention and changes the parts you did. That is the difference from a text to image generator: the composition, subject and proportions come from your image, so results stay recognisable and usable.
Under the hood, the source image is encoded and combined with your text instruction before the model denoises a new picture. In practice that means one upload can become a studio product photo, a watercolor illustration, a night version of a room, a cleaned up headshot, or a fully rendered concept of a rough drawing. The same workflow covers photo to AI art, style transfer, background replacement, relighting and object edits.
On this page you can generate an AI image from an image right away with our fast default model. Inside Krater the same upload works with every image to image model we host, side by side, with higher resolutions, multiple outputs and reference images.
Every image model in one place
Pick the model for the job
The free run uses Flux 2, a fast model with strong quality. Inside Krater you choose from every image to image model below, compare results side by side, and never juggle another subscription.
Techniques
Style transfer, background swaps and every other image to image edit
Image to image AI is one input and one instruction, but it covers very different jobs. These are the four you will use most, with what to ask for in each case.
AI style transfer
Keep the subject and composition, change the medium: watercolor, oil paint, anime, pencil sketch, pixel art, 3D render or a clean vector look. Name the style and add "keep the composition and subject the same" so the model repaints instead of reinventing.
Background replacement
Swap a cluttered room for a studio backdrop, a beach or a marble tabletop while the subject stays pixel accurate. Describe the new scene, the lighting direction and the surface the subject stands on for realistic shadows.
Photo editing with text
Change colors, seasons, weather, time of day, outfits or materials with a sentence. Start the prompt with what must stay the same ("keep the car exactly the same"), then describe the change, and the model edits instead of regenerating.
Sketch and concept to photo
Turn a line drawing, blueprint, 3D wireframe or rough render into a photorealistic image. Add camera language such as "shot on a 50mm lens, soft daylight" to steer the realism.
How to write an image to image prompt
- State what stays fixed first, then what changes. The model treats the source image as truth for everything you do not mention.
- Use concrete nouns and light: "warm golden hour sunlight with long shadows" beats "make it nicer".
- One change per run gives the cleanest result. Chain runs for bigger transformations inside Krater.
- Upload the sharpest, largest source you have. Detail in the input becomes detail in the output.
What people create with image to image AI
One upload, hundreds of outcomes
Image to image AI is the fastest way to get a usable visual out of the photo you already have: convert, restyle, relight or reimagine it.
Product photos
Turn a phone snapshot into a clean catalog image, lifestyle scene or seasonal variant without a reshoot.
Portraits and headshots
Polish lighting, swap the backdrop, or restyle a selfie into a professional profile picture.
Art styles
Reimagine any picture as watercolor, oil paint, anime, line art, pixel art or a 3D render while keeping the composition.
Marketing visuals
Create ad variants, social posts and banners from one source image, each with a different scene or mood.
Real estate and interiors
Restage rooms, change wall colors, swap furniture or show the same space in daylight and at night.
Sketches to concepts
Bring a rough drawing, wireframe or mockup to life as a realistic render or a finished illustration.
Suitable for everyone

Image to image AI generator FAQ
What is image to image AI?
Image to image AI takes an existing picture plus a text instruction and produces a new picture. Unlike text to image, it starts from your photo, so the subject, layout and details you do not mention stay intact while the parts you describe change.
Is this image to image AI generator free?
Yes, your first run on this page is free and needs no account. To keep generating, and to unlock every image model, higher resolutions, multiple outputs and reference images, get started on Krater with a paid workspace.
What is the difference between image to image and text to image?
Text to image creates a picture from words alone, so the result can look nothing like what you had in mind. Image to image starts from your upload, keeps its composition and subject, and only changes what your prompt describes. It is the better choice whenever you already have a photo, sketch or product shot.
Which AI image models can I use?
The free run uses a fast, high quality default. Inside Krater you can switch between every image to image model we host, including Flux, Nano Banana, GPT Image, Seedream, Kling, Qwen, Ideogram and Recraft, and compare their results on the same upload.
What kind of images work best?
Clear, well lit photos with a visible subject give the most reliable results. PNG, JPG and WebP up to 6 MB are accepted here. Product shots, portraits, rooms, sketches, screenshots and anime or cartoon frames all work well.
How do I write a good prompt for an AI image generator from image?
Describe the outcome, not the steps. Name what should change (background, style, lighting, materials) and what must stay the same (the product, the face, the text). Short, specific sentences beat long lists.
Can I turn a photo into art, anime or a 3D render?
Yes. Style transfer is one of the most common uses: ask for watercolor, oil paint, anime, line art, pixel art, clay or a 3D render and the model repaints your photo while keeping the composition.
Does it work on my phone?
Yes. The page works in any modern mobile browser. Tap the upload area to pick a photo from your camera roll, type the change, and download the result.
What happens to my uploaded image?
Your upload is sent to the model provider only to produce the result and is never used by Krater to train models. On this page nothing is saved to an account. Inside Krater, your images are stored in your private workspace and you can delete them at any time.
Are the generated images watermarked, and can I use them commercially?
Results are delivered without a watermark. You can use what you create for personal and commercial projects, as long as you have the rights to the image you upload.
