Features
- Product stays pixel-true——Shape, color, logo and label stay exactly as shot — only the scene, light and layout are rebuilt. Deformation is a ship-blocking bug here.
- Poster plus prompt——Beyond the finished poster, the full English prompt ships as a code block — paste it into Midjourney, Flux or Ideogram.
- Big clean headlines——Short, huge headlines over clean space. Dense small print is better added later — every word is spell-checked before delivery.
- 4 styles, 3 sizes——Luxury, street, tech-spec and food styles; universal 3:4, social 9:16 and square 1:1, switch anytime.
How it works
- Upload product photo One phone photo of your product is enough. Messy background is fine — it just needs to be complete and sharp.
- Pick style, write copy Choose from 4 styles and 3 sizes, write selling points and headline — or tap a preset look to fill the brief in one click.
- Get poster plus prompt Loomi renders the finished poster with the full prompt attached: ask for a revision in plain words, or copy the prompt away.
FAQ
- Can one phone photo become a pro poster?
- Yes. One sharp phone photo of your product is the ideal starting material. Keep the product complete with no heavy blur or cropping — messy backgrounds are fine. Loomi cuts the product out and rebuilds the scene and light. Food, beauty and footwear work fastest.
- How do I write a poster prompt that looks real?
- Use the formula: preserve product + subject + new scene + light and texture + style and layout + empty top space for the title. Simpler backgrounds look pricier, shorter and bigger titles look realer. Or just write the selling points and let Loomi draft the headline.
- Midjourney or Flux — which is better?
- No single champion: Midjourney wins on mood but garbles long text, while Flux, Recraft and Ideogram nail text and layout. In Loomi you skip the choice — the same brief renders a finished poster, and the included prompt pastes into any of those tools.
- Is the ad poster prompt designer free?
- You can try it free online in Loomi with no software to install. Log in, send the product photo plus copy, and go — quotas follow the rules shown on the page.
- How can you tell if an ad image is AI-made?
- Check three things: mangled product details, garbled small headline text, and off lighting or reflections. Top-tier outputs keep getting harder to spot — for shopping, stick to official stores and real customer photos.
- How many steps does a beginner need?
- Three: 1 upload the product photo, 2 pick a style and write selling points plus headline, 3 take the finished poster and prompt. Preset looks fill the whole brief in one click — just follow the page.
