Image to image AI

Image to image AI.
Reference-driven generation.

Drop a reference photo and a prompt, and Postcrest's image-to-image AI generates a brand-new image that inherits the style, composition or character of your reference — powered by Flux Kontext, Nano Banana Pro, Seedream and SDXL img2img.

What image-to-image is for

Use a reference to guide the output.

Image-to-image is the bridge between prompt-only generation and full control — when text alone can't describe the look you want.

Style transfer
Paint a photo in the style of an illustration — or turn a sketch into a photoreal render.
Composition transfer
Keep the framing and pose from a reference, restyle everything else with a new prompt.
Character transfer
Generate the same character in new scenes by passing their portrait as the reference.
Product re-shoots
Use one clean product photo as the reference and generate it in unlimited lifestyle scenes.
Mood / colour transfer
Force a brand palette and mood onto every generation — drop the brand image as a reference.
Sketch to photo
Sketch a rough idea, pass it as reference, generate the polished photoreal version.

Paint a photo in any aesthetic.

Drop a reference image that captures the mood — Wes Anderson palette, Studio Ghibli illustration, oil painting, retro film — and have Postcrest carry that style into a brand-new subject. Perfect for brand visual systems, mood-locked campaigns and aesthetic experiments.

  • Mood + colour
    Carry brand palette, lighting and texture from one image to the next.
  • Style strength slider
    From subtle nudge to full transformation — one slider controls it.
  • Multi-reference
    Pass a style ref plus a composition ref plus a character ref — all three at once.

Character + composition

Same character. New scene. Locked composition.

Lock framing, pose or character identity from a reference, then change everything else with a prompt. Generate the same AI character in unlimited scenes, or keep the same framing from a hero shot while changing setting, lighting and props.

  • Character carry-over
    Same identity in new scenes — pair with custom AI models for max consistency.
  • Composition lock-in
    Keep the framing, change the subject — useful for brand-template campaigns.
  • Powered by Flux Kontext
    The strongest instruction-following image-to-image model on the market.

Included with Postcrest

Multi-model image-to-image pipeline.

Each model is better at different transfer tasks. Postcrest routes your reference + prompt to the right model automatically — or lets you override.

Flux Kontext
The strongest model for instruction-following image editing — "keep her, change the dress to red".
Nano Banana Pro Edit
Best at preserving identity, typography and fine product detail while you change the scene.
Seedream Edit
Cinematic style transfer and re-shoot quality — the model for editorial and ad creative.
Strength + denoise control
Slide between "just nudge the reference" and "reimagine from scratch" with one slider.
Multi-reference
Pass a character reference plus a style reference plus a composition reference — all three at once.
Up to 4K output
Image-to-image doesn't downgrade resolution — output is print-ready and watermark-free.
How it works

Image-to-image in three steps.

01
Upload a reference
A photo, sketch, illustration or AI generation — anything that captures the look you want.
02
Add a prompt
Describe what should change, what should stay, and the desired style.
03
Generate
Postcrest blends reference and prompt and outputs the new image at up to 4K.
How Postcrest compares

Why creators move from Midjourney img2img and Stable Diffusion.

Most image-to-image apps are limited to one model and one transfer mode. Postcrest bundles three best-in-class models and lets you stack references.

Midjourney --sref
Single model, style only
Midjourney's --sref works for style but not composition or character — and is locked to MJ's one model.
With Postcrest
Style + composition + character transfer with three different models — auto-picked per task.
Stable Diffusion ControlNet
Powerful but complex
ControlNet supports composition lock-in but requires installing extensions, picking the right control type, and managing local GPU.
With Postcrest
Same ControlNet-class quality with auto-routing, hosted, no setup, plus Flux Kontext for instruction following.
DALL·E (ChatGPT)
Limited image-to-image
Image-to-image in ChatGPT is conversation-based and limited — no strength control, no multi-ref.
With Postcrest
Strength slider, multi-reference support, per-model override — the full image-to-image toolkit.

What creators say about Postcrest.

"I drop our brand image as a style reference and every generation comes back on-palette. Killed our brand-visual inconsistency overnight."

L
Lina
Brand designer

"Flux Kontext is the model I switched from Midjourney for. Instruction-following at this level is wild."

P
Phenny
Creator

"Product re-shoot pipeline used to be a photographer day. Now it's a reference image + a prompt + 30 seconds."
