Style Transfer Prompter

🎨 Style Transfer Prompter

Generate style-only prompts from a reference image for FLUX, Krea, and other Image-to-Image models.

Unlike traditional image captioning, Style Transfer Prompter intentionally ignores the image content. Instead, it instructs a local VLM (Qwen3-VL) to describe only the visual style—brushwork, line quality, edge treatment, rendering technique, textures, and color palette.

As a result, the target image keeps its original subject while adopting the artistic style of the reference image.

✨ Features

✅ Style-only prompt generation

No characters, objects, poses, or scene descriptions—only stylistic attributes.

✅ Four analysis modes

🎨 Artistic / Illustration

🧊 3D / Render / CGI

📷 Photorealistic / Cinematic

✏️ Anime / Manga

✅ Identity preservation

keep_identity helps preserve the identity of the target subject.

✅ Painterly edge detection

painterly_edges describes unfinished brush strokes, watercolor bleeding, rough edges, and loose paint transitions.

✅ Color control

keep_original_colors

preserve the original colors of the target image

or adopt the palette of the reference image

✅ Custom prompt extension

extra_prompt appends your own instructions to the generated prompt.
