🌐 Website Hero Images

A website hero image sits right at the top of your homepage, forming the crucial first impression visitors get when your page loads. Creating these wide, visual banners with AI saves hours of hunting through tired stock photo libraries or spending thousands on custom commercial shoots.

Why AI works for this

Why ChatGPT is great for website hero images

ChatGPT excels at building website hero images because it understands spatial relationships better than most tools, letting you position your subject on one side while leaving empty background space on the other. Because website hero banners often need to match across multiple landing pages, ChatGPT’s in-thread conversational editing lets you generate a strong base image and adapt it across a single chat session without losing your core brand aesthetic.

💬

The secret: keep editing in the same chat. Ask for small changes (“keep everything the same, but…”) instead of starting again, and your designs stay consistent.

The techniques

4 things that make the difference

1

Compositional Negative Space

Hero sections require generous empty room for headlines, subheaders, and call-to-action buttons. You must prompt for asymmetric compositions so the focal point does not fight with your web copy. Once you hit a layout you like in ChatGPT, you can keep building inside that same chat thread to generate companion banners with matching space.

> Follow-up example: *”Keep this exact lighting and colour palette, but shift the main subject to the right third of the frame so the left side stays completely empty for web text.”*

Pro tip: Always specify which side of the image should remain clear based on your website template design.

2

Aspect Ratio and Horizontal Scope

Standard web banners rely on ultra-wide horizontal framing, typically 16:9 or wider panoramic spreads. Prompting for sweeping horizontal scope prevents AI from squeezing complex visual elements into a crowded frame. This keeps the scale looking intentional on wide desktop screens.

💡

Pro tip: Requesting wide focal lengths like 24mm helps push visual elements to the background while stretching the overall landscape smoothly across the screen.

3

Contrast Control for Text Readability

Your text must remain crisp and readable over the background image. If the background contains jarring bright spots mixed with deep shadows, text overlays become unreadable. You need prompts that enforce consistent tonal balance across the open areas of your banner.

💡

Pro tip: Match your lighting requests to your site’s font colour. Use dark ambient backgrounds for white text or bright softbox lighting for dark text.

4

Depth of Field and Focus Isolation

Blurring the background keeps your visitors focused on your core product or message. Sharp foreground subjects paired with soft background falloff create professional visual depth without cluttering the user experience.

Pro tip: Mention specific camera lenses, like an 85mm prime lens shot at f/1.8, to get natural optical background blur instead of artificial-looking digital fuzz.

Adding text

Getting words onto your image

AI generators can render short, high-impact headlines directly onto your hero banner with good visual accuracy. However, web design often requires text that changes dynamically across different screen sizes. You have two solid paths forward when managing text for your hero sections:

Option 1Generate Text In-Image

Include your exact short headline in double quotes within the prompt. If the rendered letters come out slightly warped or misspelled, ask the AI to re-render the image while keeping the overall layout intact.

Option 2Overlay Text in Code or Canva

Prompt the AI to build a clean background image with zero text, focusing purely on perfect composition and negative space. Take the generated image and drop it into Canva, Figma, or your web builder like Webflow or WordPress to add real HTML text overlays for perfect typographic control and mobile responsiveness.

Using another tool? The prompt formula and 10 examples above use generic style and camera descriptors, meaning they will work immediately if pasted into Midjourney, Gemini, or flux models. Keep in mind that ChatGPT’s conversational approach to adjusting space inside an existing image thread is unique. If you switch to tools like Midjourney, you will need to use their native pan, zoom, or image-to-image remix buttons to achieve the same layout tweaks.

Avoid these

Common mistakes

✕
Centreing the main subject directly in the middle of the frame, which causes background detail to fight with centreed H1 text and CTA buttons.
✕
Using complex, high-contrast background patterns behind areas meant for small body copy or navigation links.
✕
Forgetting to specify horizontal 16:9 aspect ratios, resulting in tall square images that get awkwardly cropped on desktop browser windows.
✕
Overloading the prompt with too many competing subjects, creating visual clutter that distracts from the core brand message.
✕
Starting every new page header from scratch with a brand-new prompt thread instead of building on a style anchor image in the same conversation.
