FLUX.1 Kontext edits in about 25 seconds. ~25s — typical time, FLUX.1 Kontext 5–20 — credits per image, by model 17 — models to choose from 10 MB — max upload ## Example prompts for Image to Image The same prompts are behind the “Try an example” button in the input box; each click loads the next one. ### Change season Make it winter — snow on the ground and rooftops, bare trees, cold overcast light ### Swap background Replace the background with a plain studio backdrop, keep the subject exactly as is ## Made with these models Images generated on this site with the same models. ## Will Image to Image work on your photo? Match what is wrong with your image to what this tool can realistically do. Where it cannot help, the row says which tool can. ### Swap a background, recolour, add or remove an object Good match These are the edits the models handle most reliably, because you can name both the change and what must stay. ### Keep a face identical through the edit Partial improvement Add “keep the face exactly the same” and prefer Nano Banana, which follows instructions most literally. Check the result at full size. ### Readable text inside the picture Partial improvement GPT Image 2.5 and Seedream handle lettering best. Put the exact words in quotes and keep them short. ### Fix a blurry, noisy or damaged photo Use another tool Editing models repaint; they do not repair. For quality problems use the [Image Enhancer](https://www.aiimagetools.net/tools/ai-image-enhancer) ## Why Image to Image on AI Image Tools ### Edit with a sentence, not a mask "Make it winter", "change the shirt to red", "replace the background with a plain studio backdrop". No brushes, no layers. ### Four editing models, one upload FLUX.1 Kontext is the fast default. Nano Banana follows instructions most literally and accepts several reference images. Seedream 5 and GPT Image 2.5 push detail and resolution. ### The rest of the photo survives The models are told to change only what you asked for. Name what must stay the same and it will. ### Pay per returned image Variations run in parallel and you are charged only for the ones that come back. Failed runs cost nothing. ## Every image model in one place Pick any of these from the Model menu above; the price is shown before you generate. Each name links to what that model is good at.

Phone photos are fine. - Step 2 ### Describe the change Name the one thing to change and what should stay. "Snow on the ground and rooftops, keep the building and the people exactly as they are." - Step 3 ### Generate and compare Ask for 2 or 4 variations, pick the best, and run it through the upscaler if you need a bigger file. ## Get a better result A few choices before you upload change the output more than any setting on this page. ### Upload the original file Screenshots and images re-saved by messaging apps carry compression the model then has to work around. Find the earliest copy you have. ### One change per run Stacking five instructions into one prompt is where results go sideways. Each run costs a few credits and takes about half a minute, so chain them. ### Fix quality first, then edit A soft or noisy source produces a soft or noisy edit. Clean it up, then come back. [Image Enhancer](https://www.aiimagetools.net/tools/ai-image-enhancer) ## How to write a prompt for Image to Image ### One change per run Stack edits across runs instead of listing five in one prompt; each run is cheap and fast. ### Say what must stay "Keep the face, pose and background" is the most useful sentence you can add. ### Describe the result, not the process "The wall is painted sage green" works better than "repaint the wall". ### Match the light If you add an object, say where the light comes from so it sits in the scene. ## Pricing Every tool draws from one balance. 40% OFF No hidden fees • Cancel anytime • Unused credits roll over 16% OFF - Save $18.8 $8.3/month $9.9/month $100/year billed yearly 480images / year $0.21 per image on Nano Banana - [Included] 2,400 Credits renew yearly - [Included] Or 120 images in 4KGPT Image 2.5 · 4K - [Included] All 26 tools, one balance - [Included] All 18 models, including the 4K tiers - [Included] Download without watermark 20% OFF - Save $70.8 Popular $24.0/month $29.9/month $288/year billed yearly 1,920images / year $0.15 per image on Nano Banana - [Included] 9,600 Credits renew yearly - [Included] Or 480 images in 4KGPT Image 2.5 · 4K - [Included] All 26 tools, one balance - [Included] All 18 models, including the 4K tiers - [Included] Download without watermark 40% OFF - Save $238.8 $30.0/month $49.9/month $360/year billed yearly 4,320images / year $0.083 per image on Nano Banana - [Included] 21,600 Credits renew yearly - [Included] Or 1,080 images in 4KGPT Image 2.5 · 4K - [Included] All 26 tools, one balance - [Included] All 18 models, including the 4K tiers - [Included] Download without watermark Swipe to compare plans → ## Image to Image: frequently asked questions ### ### Will it change parts of the photo I didn't mention? It is instructed not to. If something drifts, add "keep everything else exactly as it is" to the prompt or switch to Nano Banana, which follows instructions most literally. ### ### Which model should I pick? Start with FLUX.1 Kontext: it is the fastest for edits and costs 5 credits. Nano Banana follows instructions very closely but can take a few minutes when busy. GPT Image 2.5 and Seedream 5 Pro give the most detail at 13 to 20 credits. ### ### Can I upload phone photos? Yes. JPG, PNG, WebP and HEIC are accepted up to 10 MB. Very large images are downscaled by the model, so anything around 2000 pixels on the long side is plenty. ### ### How many variations can I get? 1, 2 or 4 per run, each charged only when it comes back. ### ### What happens if a generation fails? You are only charged when an image comes back. If the model fails or times out, nothing is deducted and you can simply run it again. ### ### What happens to my photos? Your upload is sent to the model provider only to produce the result. The result is stored in your My Creations gallery on our own storage, and you can delete it there at any time. ### ### Can I use the results commercially? You keep ownership of what you upload and what you generate, on every plan; see the Terms of Service. Free downloads carry a small watermark, paid plans download without one. ## Change one thing, keep the rest Upload a photo at the top of the page and say what should be different.
