🖼️ Free Image Prompt Generator

Turn a simple idea into a hyper-detailed image prompt — with subject, style, lighting, camera and composition baked in.

Most people type a few words into Midjourney or DALL·E and get a flat, generic image. The difference between a mediocre result and a stunning one is almost always the prompt — the specific details about subject, style, lighting, lens, mood and composition.

This free image prompt generator does that work for you. Describe what you want in plain English, answer a couple of quick questions, and get a richly detailed prompt engineered to produce the image you actually had in mind.

Tips for better results

Name the medium first — 'photograph', 'oil painting', '3D render' — so the model knows the overall look.
Add a lens and aperture (e.g. 85mm f/1.8) to control depth of field in photoreal images.
Describe the lighting (golden hour, soft studio, neon) — it sets the entire mood.
Specify composition: close-up, wide shot, rule of thirds, centered.
Upload a reference image in the tool to anchor style or character consistency.
