Image to Image AI Editor — Multi-Reference Photo Transformation
Traditional image editing tools treat each photo as an isolated canvas. This image to image AI editor lets you feed up to 16 reference images into a single edit — GPT Image 1.5 Edit combines brand guides, product shots, and style boards into one coherent output. Seedream 4.5 Edit handles artistic style transfer at native 4K with 14 references, preserving subject identity while completely changing the visual language. Flux 2 Pro Edit processes each transformation in seconds at 1K or 2K resolution. Nano Banana Pro maintains face and outfit coherence across edits at up to 4K. Upload JPG, PNG, or WebP files up to 10 MB and describe the change in natural language.
AI Models for Image Editing — Reference Counts Compared
The number of reference images you can attach changes what is possible. Below is each model's editing approach, resolution ceiling, and reference image limit.
GPT Image 1.5 Edit
OpenAI · 16 Reference Images
Accepts up to 16 reference images per edit — the highest count in any AI image editor. Feed a brand guide, product photography, a target layout, and a color palette in one request. The model synthesizes context from all inputs to produce edits that respect every reference simultaneously. Medium quality at 1024 px, high quality at 1536 px. Three aspect ratios: 1:1, 2:3, 3:2.
Seedream 4.5 Edit
ByteDance · 4K Style Transfer
Transforms photos into 4K artwork while preserving subject identity. Upload up to 14 reference images — style boards, art prints, color palettes — and the model maps their visual language onto your source photo. Native 4K output (up to 4096×4096 px) across 8 aspect ratios including 21:9 ultrawide. Both 2K and 4K edits render at the same cost tier.
Flux 2 Pro Edit
Black Forest Labs · 63.6% Edit Win Rate
Processes image edits in seconds — the fastest editing model in the lineup. Accepts up to 8 reference images for context-aware transformations. Holds a 63.6% win rate on multi-image reference editing benchmarks. Ideal for batch workflows: background swaps, color corrections, product photography edits at 1K or 2K across 7 ratios.
Nano Banana Pro
Google · Identity Preservation
Preserves face, hairstyle, clothing, and brand elements through every transformation — the model treats identity as a constraint, not a suggestion. Accepts up to 8 reference images for guided editing. Outputs at 1K, 2K, or 4K across 11 aspect ratios including auto-detect.
Reference-Driven AI Photo Editing
Most AI image editors accept one input photo and one text prompt. This tool goes further — attach up to 16 reference images with GPT Image 1.5 Edit to combine a brand guide, a product photo, a color palette, and a layout mockup into one coherent edit. Seedream 4.5 Edit accepts 14 references for deep style transfer at 4K. When you only need a quick background swap or object removal, Flux 2 Pro Edit handles it in seconds.
Image to Image AI Editing Workflows
Each use case maps to a specific model based on its editing strength. Below are six common workflows and the engine best suited for each.
Artistic Style Transfer
Recommended: Seedream 4.5 Edit (14 references)
Upload your photo plus up to 14 style references — art prints, film stills, color palettes — and Seedream 4.5 Edit maps their visual language onto your subject. Native 4K output preserves fine detail through the transformation.
Photo Enhancement & Restoration
Recommended: Nano Banana Pro (4K detail)
Recover detail lost to compression, low light, or aging. Nano Banana Pro reconstructs textures, corrects color shifts, and sharpens edges while preserving the original composition. Output at 1K, 2K, or 4K resolution.
Background Replacement
Recommended: GPT Image 1.5 Edit (16 references)
Describe the new background in your prompt or upload references showing the target environment. GPT Image 1.5 Edit understands spatial context — foreground subjects maintain correct lighting, shadows, and perspective relative to the new scene.
Object Addition & Removal
Recommended: Flux 2 Pro Edit (fastest)
Add, remove, or swap objects in seconds. Flux 2 Pro Edit completes each edit in under 10 seconds — ideal when iterating through multiple object placements or testing different props. Accepts up to 8 reference images for guided placement.
Resolution Upscaling to 4K
Recommended: Seedream 4.5 Edit or Nano Banana Pro
Re-generate your image at a higher resolution tier while preserving the original composition. Seedream 4.5 Edit outputs native 4K (4096×4096 px) across 8 aspect ratios. Nano Banana Pro reaches 4K across 11 aspect ratios. Both add realistic detail that simple interpolation cannot.
Product Mockup Compositing
Recommended: GPT Image 1.5 Edit (16 references)
Combine a product photo, a lifestyle background, a brand color guide, and a layout template into one edit. GPT Image 1.5 Edit processes all 16 references simultaneously, keeping text legible and brand elements consistent. Generate multiple mockup variants for rapid A/B testing.
Image to Image Prompt Templates
Copy these editing prompts directly. Each includes the recommended model and the type of transformation it performs.
Product Scene Swap
Best with GPT Image 1.5 Edit — multi-reference compositing
"Place this product on a sunlit wooden kitchen island. Morning light from the left window, subtle shadow behind the product, a fresh basil sprig to the right. Keep all product labels and text completely legible. Warm color temperature, lifestyle photography style."
Portrait Style Transfer
Best with Seedream 4.5 Edit — 4K artistic transformation
"Transform this portrait into a Renaissance oil painting style. Keep the face structure, expression, and gaze direction identical. Apply visible brushstroke texture, warm Rembrandt lighting from the upper left, dark umber background. Maintain eye color and hair detail. 4K output, 3:2 ratio."
Architecture Time-of-Day Shift
Best with Flux 2 Pro Edit — fast iteration
"Change this building exterior to blue-hour twilight. Add warm interior lighting visible through windows, wet pavement reflections, a deep indigo sky with orange horizon gradient. Preserve all architectural details and signage. Real estate photography style."
Damaged Photo Restoration
Best with Nano Banana Pro — detail preservation at 4K
"Restore this vintage photograph: remove all scratches, creases, and water damage. Reconstruct missing portions of the face and clothing using context from undamaged areas. Enhance contrast and sharpness while keeping the warm, aged tonal quality. 4K output."
Prompting for AI Photo Editing
- • Name the transformation explicitly - State the edit type first: 'Change the background to...', 'Apply oil painting style to...'. Models interpret direct instructions more accurately than vague requests.
- • Anchor what must stay unchanged - Specify preservation targets: 'Keep the subject's face, hair, and clothing identical.' Without an explicit anchor, the model may re-interpret the entire image.
- • Attach reference images for context - Upload references showing the target style, palette, or composition. GPT Image 1.5 Edit accepts 16, Seedream 4.5 Edit 14, Flux 2 Pro Edit and Nano Banana Pro each 8.
- • Choose resolution before generating - Seedream 4.5 Edit and Nano Banana Pro support 4K. Flux 2 Pro Edit caps at 2K. GPT Image 1.5 Edit outputs 1024–1536 px. Pick the tier that matches your final use case.
How Image to Image AI Editing Works
Upload, describe, generate. Each edit preserves your original composition while applying the requested transformation.
Upload Photos and References
Upload the base image you want to edit. Optionally attach reference images — style boards, brand guides, color palettes — to guide the AI. Supported: JPG, PNG, WebP, up to 10 MB per file.
Describe the Edit
Write a natural-language prompt specifying what should change — style, background, objects, lighting — and what must remain intact. Select the model matching your reference count and resolution needs.
Generate and Compare
Receive the edited image in 5–60 seconds depending on model and resolution. Output is watermark-free in PNG or JPEG. Re-run on a different model to compare interpretations.
