Describe the idea
Write what you want to see in plain language. Naming the subject and the purpose matters more than length.

Image Prompt Generator
Describe a rough idea, pick the image type, style, target model, and aspect ratio, and the image prompt generator writes a structured prompt, a short version, and a negative prompt you can copy.

Use in Image GeneratorWhat the Image Prompt Generator Does
It turns a short description into prompt language an image model can act on. Instead of guessing at phrasing, you set the image type, visual style, target model, and aspect ratio, and get a prompt that names subject, composition, lighting, and what to keep out of frame.
- Input
- A short idea plus image type, style, target model, and ratio
- Output
- A full prompt, a short prompt, and a negative prompt
- Best for
- Anyone writing prompts for product shots, posters, or portraits
How to Build a Prompt
Four steps from an idea to copy-ready prompt text.
Set type and style
Choose the image type and the visual style so the prompt uses the right vocabulary for that category.
Pick model and ratio
Select the model you plan to use and the aspect ratio, so phrasing and framing match the destination.
Generate, then improve
Build the prompt, review it, and optionally run the AI improvement pass to tighten wording and add missing detail.
What You Get Back
Three prompt versions for three different situations.
Image prompt
The full prompt with subject, composition, lighting, style, and framing spelled out in order.
AI-improved prompt
An optional rewritten version that tightens phrasing and fills gaps the short description left open.
Short prompt
A compressed version for interfaces with tight input limits or for quick iteration.
Negative prompt
The list of things to keep out of the image, such as text, watermarks, or distorted details.
Controls That Shape the Prompt
Each control changes the wording, not just the label.
Image type
Product photo, portrait, poster, logo, social graphic, or illustration. This sets which composition terms appear.
Style
Photorealistic, cinematic, editorial, minimal, 3D render, or anime, which drives lighting and rendering language.
Target model
GPT Image, Midjourney, Flux, Stable Diffusion, or DALL-E. Phrasing conventions differ between them.
Aspect ratio
Square, landscape, vertical, or portrait, so framing and negative space suit the final placement.
What People Build Prompts For
Frequent jobs that start here.
Ecommerce product shots
Write prompts that name surface, lighting, and negative space so a product still leaves room for headline copy.
Build a product prompt
Thumbnails and social graphics
Set a vertical or landscape ratio and a high-contrast style so the result reads at small sizes.
Build a social prompt
Portraits and headshots
Describe framing, lens feel, and lighting direction instead of relying on the model to guess a look.
Build a portrait prompt
Posters and logo concepts
Plan layout and typography space up front, and use the negative prompt to control unwanted text.
Build a poster promptCheck the Prompt Before You Spend a Generation
Four quick checks that reduce retries.
Confirm the subject is singular
If the prompt describes two competing subjects, split it into two prompts instead of one crowded frame.
Check framing against the ratio
A vertical ratio needs vertical composition language. Mismatches are the most common cause of awkward crops.
Reserve space for copy
If text will sit on the image later, make sure the prompt asks for negative space in the right place.
Read the negative prompt
Remove exclusions you do not actually need, because over-long negative prompts can flatten the result.
What to Expect
Boundaries worth knowing before you rely on it.
It writes prompts, not images
Generating the picture happens in an image workflow. This step only produces the text you send there.
Model behavior still varies
The same prompt returns different results across models and versions. Treat the first output as a test.
Text inside images is unreliable
Asking for exact wording in an image often fails. Plan to add real typography during layout instead.
Image Prompt Generator FAQ
Common questions about writing prompts for AI image models.
Which models does the image prompt generator write for?
You can target GPT Image, Midjourney, Flux, Stable Diffusion, or DALL-E. The selection changes phrasing conventions and how parameters are described, so pick the model you actually plan to use.
What is a negative prompt for?
It lists what should not appear, such as text, watermarks, extra limbs, or cluttered backgrounds. Keep it short and specific, because long exclusion lists can weaken the main subject.
Do I need an account to build a prompt?
No. Building the prompt happens in your browser from the controls you select. Generating an actual image is a separate workflow with its own requirements.
Why are there three prompt versions?
The full prompt carries all detail, the short prompt fits tighter input limits and fast iteration, and the negative prompt controls exclusions. Different tools and stages need different lengths.
Can I use the prompt right away?
Yes. Copy it into your own tool, or open it directly in image generation to test it. Reviewing the framing against your chosen aspect ratio first usually saves a retry.
