Image To Image API for Visual Restyling and Image Editing
Build AI image features that start from a real image, not a blank prompt. With Kie.ai’s Image To Image API, developers can test models, transform source images, and deploy image editing, restyling, and variation workflows into production.
Popular Image To Image API Models on Kie.ai
Kie.ai supports several popular models for Image To Image API workflows, giving developers more flexibility when building image editing, visual transformation, and style transfer features. The options below highlight a few well-known models available on Kie.ai, rather than the complete list of supported models.
GPT Image API
Powered by OpenAI, GPT Image API is a strong option for Image To Image API workflows that require clear instruction following and refined visual editing. On Kie.ai, developers can access models such as GPT Image 1.5 and GPT Image 2 to transform uploaded images into polished new outputs, whether the goal is product image refinement, creative restyling, reference-based editing, or more controlled image transformation inside user-facing applications.
Nano Banana API
For teams that want faster and more flexible Image To Image API experiences, Kie.ai also supports Google’s Nano Banana series, including Nano Banana, Nano Banana Pro, and Nano Banana 2. These models are well suited to image variation, lightweight editing, social-style visual effects, and creative image transformation workflows where speed, responsiveness, and easy integration all matter.
Seedream API
ByteDance’s Seedream series brings another compelling option to Kie.ai’s Image To Image API offering, with supported models such as Seedream 4.5 and Seedream 5.0 Lite. If your product focuses more on visual quality, aesthetic restyling, or turning existing images into more striking creative assets, Seedream can work especially well for design tools, marketing content generation, e-commerce visuals, and other image-to-image use cases that benefit from stronger stylistic output.
Key Features of Kie AI Image To Image API
Multi-Model Image To Image API for Flexible AI Image Transformation
A strong Image To Image API should give developers room to choose the model that matches the task, rather than forcing every image editing workflow into one output style. Kie.ai supports 30+ Image To Image API model options, including popular choices such as GPT Image API, Nano Banana API, and Seedream API, allowing teams to compare results across AI image transformation, prompt-based image editing, photo restyling, and image variation workflows. This makes AI Image API development more flexible for products that care about source image preservation, visual quality, style range, generation speed, and cost control.
Prompt-Based Image To Image API for Visual Editing
A prompt-based Image To Image API allows users to upload a source image and describe the exact visual change they want. The prompt can guide background replacement, color changes, lighting adjustments, object details, clothing updates, scene mood, or creative style direction, while the original image remains the visual starting point. This makes AI image editing with prompt more controllable than text-only generation and more scalable than manual design work.
30+ Image To Image API for Photo Restyling and Composition Preservation
An Image To Image API for photo restyling can transform an existing image into a new visual style while still preserving the original composition, subject structure, depth, and key details. Users can turn portraits, product photos, character images, or scene references into anime, oil painting, cinematic, fantasy, 3D, sketch, editorial, or branded visuals. The result looks new, but the image-to-image transformation still follows the layout and visual story of the uploaded image.
Consistent Image Variation from One Image To Image API Input
Image variation becomes more useful when the output keeps the right elements stable. With an Image To Image API, a single input image can be used to generate multiple versions while maintaining key references such as character identity, product structure, pose, layout, or brand direction. Developers can support controlled variation for campaign assets, product previews, character design, avatar systems, and creative testing without producing disconnected or random-looking results.

Image To Image API Magic: From Simple Edits to Visual Transformation
Image Style Transfer
Turn an existing image into a completely new visual style without losing the original idea. Image To Image API workflows can transform portraits, products, landscapes, or character images into anime, sketch, oil painting, cinematic, fantasy, 3D, pixel art, and other creative looks while keeping the main subject and structure recognizable.
Background Replacement
Replace dull or distracting backgrounds with scenes that better match the final use case. A portrait can be placed in a studio, a product can move into a lifestyle setting, and a simple image can be rebuilt inside a more polished visual environment. This makes background editing one of the most practical Image To Image API applications for creative tools and commercial workflows.
Object Removal and Image Cleanup
Remove unwanted elements such as clutter, distracting objects, watermarks, or imperfections while keeping the overall image natural. Instead of just erasing parts of a photo, Image To Image API can regenerate surrounding areas so the final result feels cleaner, more complete, and visually consistent.
Photo Restyling
Restyle an uploaded image while preserving its original composition, subject structure, and key visual details. A photo can be reimagined with a different mood, color treatment, artistic direction, or branded aesthetic, making photo restyling a strong fit for apps that want to offer more than basic filters.
Consistent Character and Face Variations
Generate multiple variations from one source image while keeping the same face, character identity, or core layout intact. Users can explore different outfits, hairstyles, lighting, moods, or scene styles without losing continuity, which is especially useful for avatar tools, character design workflows, and visual series creation.
Old Photo Restoration and Enhancement
Bring faded, damaged, or low-quality images back to life through restoration and enhancement. Image To Image API can help repair scratches, improve clarity, restore missing detail, and refresh overall image quality while still respecting the original people, objects, and visual character of the photo.
Compare GPT Image, Nano Banana, and Seedream for Image Generation APIs
GPT Image, Nano Banana, and Seedream can all support text prompts, image inputs, and multi-image generation or editing workflows, but they differ in model ecosystem, output resolution options, creative control, and best-fit use cases.
