🌐 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 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.
4 things that make the difference
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.
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.
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.
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.
Build your own prompt
Use this structured prompt format to generate consistent, professional hero banners tailored to your layout needs. This formula is written generically so it works reliably in any modern AI image tool.

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:
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.
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.
Get the size right
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.
Common mistakes
Fix it in the same chat
Not quite right? Don’t start again. Send one of these follow-up requests.
Ask ChatGPT to shift subjects to the far left or far right to match your exact website grid template.
Tell the AI to darken or lighten specific background areas to ensure your site’s text colour passes Web Content Accessibility Guidelines (WCAG) contrast ratios.
Request wider camera angles if your graphic elements feel cramped near the top or bottom edges of the hero frame.
Now it’s your turn
Building website hero images with AI gives you total creative control over your site’s visual entry point. Stick to the prompt formula, protect your negative space for text, and use conversational tweaks to build a polished visual experience for your website visitors.
