1. Write the brief
Name the product or announcement and the mood. For a website hero, reserve an uncluttered area for live headline text and a button. For a promotion, use only approved offer wording.
AI banner generator
Your brief. A wide banner image.
An AI banner generator turns a written brief into website, social or promotional banner artwork. Choose a 16:9 or 21:9 image with Nano Banana Pro in the existing generator, or upload an authorized product photo to edit. Text generation costs 20 credits at 1K; a reference edit costs 40 credits at 1K. This guide provides prompts and manual setup, not an automatic banner editor.
Use only images, product assets and wording you have the rights to use, with consent from anyone pictured. This is an independent website, not affiliated with or endorsed by Google. Review offers, text and product details before publishing.
Text-to-image or editing with your authorized product photo
16:9 and 21:9 wide layouts in the selected image model
Flat image artwork; add precise typography and links separately
How to make a banner
From campaign brief to banner draft
Decide where the banner will appear before writing the prompt. Describe the focal product, background, color palette and space for your final headline.
2. Choose the layout
Open the generator, select Nano Banana Pro, and choose 16:9 or 21:9 to suit your placement. Paste a prompt or upload a product photo up to 8 MB for an edit. The link does not prefill a prompt or select a model.
3. Review before publishing
Sign in and check the displayed quote. At 1K, text generation costs 20 credits and reference editing costs 40; at 4K, the quotes are 40 and 60 credits respectively. Inspect details, then crop or resize for your destination in an editor.
Banner prompt examples
Give the composition a clear purpose
Copy a prompt into the existing tool and replace the subject with your own. These are instructions to try, not tested outputs. Add exact promotional text in an editor when spelling and placement must be precise.
Website hero
Create a wide website hero image for an independent ceramic shop. Place an original handmade mug on the right against a warm neutral background, with soft side lighting and uncluttered space on the left for a live headline and button. No text, logos or watermarks.
Seasonal product promotion
Use my authorized product photo as the reference for a wide seasonal banner. Preserve the product shape and label as closely as possible. Add a subtle autumn background with warm colors and natural light. Keep clear space beside the product for approved offer text added later. No invented discounts or brand logos.
Social announcement
Create a wide social announcement image for a local plant workshop. Use original green leaf arrangements and a potting table as the focal scene. Keep the central subject easy to crop and leave calm background space for an event title. No text or third-party logos.
Banner review
Prepare artwork for the destination
The result is a flat image draft, not an editable ad layout, HTML banner or campaign publishing service. It does not include clickable buttons or guarantee advertising results.
Check responsive crops
Preview the artwork in the actual website or social placement. Keep the product away from crop edges and add website headlines as live text where practical. An aspect ratio does not guarantee the destination pixel size or file limit.
Check product fidelity
Compare a reference edit with the original. Labels, packaging, colors and proportions can change. Reject misleading product details and fix spelling before publishing.
Finish the offer separately
Add approved dates, prices and legal copy in a layout editor. Export for the destination requirements. A generated button is part of the picture; implement real navigation in your website or ad platform.

FAQ
AI banner generator questions
Can I generate a banner from text?
Yes. Select Nano Banana Pro in the existing generator, choose a wide ratio and describe the subject, palette and layout. Leave space for a headline, then review the image before using it on your website or social account.
Can I use a product photo as a reference?
Yes. Upload an authorized photo up to 8 MB with the selected model and describe the banner setting. Ask to preserve the product, but inspect labels and proportions because exact preservation is not guaranteed.
Which banner ratios are supported?
16:9 and 21:9 are supported by Nano Banana Pro. Choose the ratio in the generator rather than relying on the prompt alone. Crop and resize the finished image for your placement; a ratio is not a guarantee of exact pixel dimensions.
Is the AI banner generator free?
No free generation is promised by this guide. With Nano Banana Pro, text generation costs 20 credits at 1K or 40 at 4K; a reference edit costs 40 at 1K or 60 at 4K. Sign in and check your balance and current quote before submitting.
Will the image include exact promotional text?
No. Exact spelling, typography and layout are not guaranteed. Request a clean background with space for text, then add and proofread your final headline, prices and offer conditions in an editor.
Does this page automatically generate or publish a banner?
No. The button opens the existing image tool; it does not prefill a prompt, select a model or submit a request. Set up the image yourself, check the quote, and publish only after reviewing the result.
