## What is image to image AI?

Image to image AI takes a picture you already have plus a written instruction and returns a new picture: the same subject with a different background, style, outfit, light or detail. Unlike text to image, it starts from your pixels, so faces, products and layouts can stay recognizable.

This site runs four image models in the browser: Google's Nano Banana 2 and Nano Banana Pro, OpenAI's GPT Image 2 and ByteDance's Seedream 5.0 Flash. Upload up to 14 pictures, refer to them as Image 1, Image 2 in the prompt, pick a model and resolution, and download the result. You can also start from text alone.

## Edit or create an image

Generator: https://image-to-image.io/create

1. Upload a picture: Add one or more JPG, PNG or WebP pictures, up to 10 MB each. Or skip this step and start from text.
2. Say what to change: Describe the edit in plain words and what to keep, for example "make it golden hour, keep her face and the dress". With several pictures, refer to them as Image 1, Image 2.
3. Generate and download: Pick the model, resolution and shape, see the price on the button, and download the image when it's ready.

## When Image To Image AI is a good fit

- You want to edit a picture by describing the change (background, style, clothes, light, objects) without Photoshop, masks or an app.
- You want four image models in one place (Nano Banana 2, Nano Banana Pro, GPT Image 2 and Seedream 5.0 Flash) without separate subscriptions or API keys.
- You want to try it free: a new account gets 10 credits (5 Nano Banana 2 images at 1K), and a daily check-in unlocks one free Nano Banana 2 1K image each day, plus bonus credits for a streak (2 on day 3, 6 on day 7).
- You want to pay per image with one-time credit packs (300 credits for $9.99, about $0.07 per Nano Banana 2 image), no subscription, and see the exact price before each image.
- Not a fit: you need unlimited free images, video, transparent PNG cut-outs, or to fine-tune a model on your own pictures.
