IMAGE TO IMAGE, EXPLAINED

Transform an existing image with a text prompt

Image-to-image generation uses an uploaded image as visual context, then applies the changes you describe. It is suited to restyling a product shot, exploring lighting and backgrounds, refining a sketch, or combining visual references while keeping a recognizable subject.

For better control, state both what should stay the same and what should change. Generate several variations and compare them, because AI results can differ even when the input image and prompt are similar.

Choose a clear source image

Use a photo, sketch, render, or other reference where the important subject is easy to identify.

Describe what to keep

Name the subject, product shape, pose, composition, or other details that should remain recognizable.

Specify the change

Explain the new style, background, lighting, material, color, or scene you want to explore.

ONE IMAGE + TEXT

One image + text. A better result.

Upload your image and describe the change. AI keeps the subject intact while refining the result.

IMAGE-TO-IMAGE FAQ

Questions about transforming images with AI

What is an AI image-to-image generator?

It creates a new image from an uploaded visual and a text instruction. The source image provides context while the prompt explains what to preserve or change.

How can I keep the original subject recognizable?

Use a clear source image and state which details must remain, such as the subject, pose, product shape, or composition. Because this is generative editing, compare multiple results and refine the prompt when needed.

Can I combine more than one image?

Yes. Fastby AI can use multiple images as references and generate a result that brings their subjects or design elements into one composition.

How is image to image different from text to image?

Image to image begins with an existing visual, making it useful for controlled variations and restyling. Text to image starts from a written idea without requiring a source image.
