AI Hero Image Generator

Generate website hero images and banner backgrounds from a topic, a document, or your own photo with the Campaign kit in Gixo Prism. The kit cuts one picture to a 1536×1024 hero banner, sets your headline and supporting line on it, and cuts the same picture to the other channels you pick, such as matching email headers, display banners, and social posts.

Campaign image, channel crops and publishing review

Choose the source image and intended audience, channel and message. Review each crop, on-image text, captions and alternative text at its final dimensions; confirm image rights and contrast before publishing. Regenerate only the selected channel when its crop or copy needs a revision.

A composed visual does not independently verify its claims. Confirm the source, rights, figures, reading order and accessibility with the intended audience before publishing.

What the hero image generator produces

A website hero banner is one channel of a Campaign kit. The kit makes one picture for your message and cuts it to each channel's exact size, so the output fits the hero section instead of being a generic square image.

Website hero banners

1536×1024 landscape banners cut for a hero section from the kit's picture, with your headline and supporting line set on top in one of 7 designs, spelled as you typed them.

One picture, one design

A hero banner, email header, and display ad made in one kit share one picture and one design, so they read as one campaign instead of three unrelated images. From the Professional plan up, the design is built on your Brand Kit.

Matching campaign channels

The same kit covers Instagram post, Instagram Story, LinkedIn post, X, Carousel, TikTok cover, YouTube thumbnail, Website banner, Email header, Banner ad, and Section background, each cut to its own size, with captions and alt text where the channel takes them. Print, poster, video and book formats are not part of it.

2
Say what the page is promoting

Give the topic, a document in your Gixo account, or your own photo. Pick the website hero channel, plus any other channels the campaign needs.

3
Write the message and pick a design

A headline and a supporting line, set on the banner by Prism's renderer. From the Professional plan up, the design uses your Brand Kit, so the banner belongs to your site, not to a stock library.

Review and export

Generated imagery deserves a human pass — check it, make a new picture if needed, and download the banner as PNG, JPG, and WebP, or the whole kit as a ZIP, for your site, email, or campaign.

Where this fits in the Prism toolkit

  • Hero images are AI-generated imagery. The picture comes from an image model, which is the right tool for an evocative banner background; the words on it come from Prism's renderer. Review the picture before it ships; making a new one uses plan capacity.
  • When the visual carries data, use the makers instead. Prism's chart, diagram, flowchart, and card makers are deterministic — no AI in the rendering loop — so figures and labels render exactly. A hero banner sets the scene; the makers carry the numbers.
  • The entry plan covers both. Hero banners through the Campaign kit, the deterministic makers, and AI infographics are all included in Prism from $10/month — no per-export caps. Making a kit's picture and captions uses plan capacity; downloads do not.

Frequently Asked Questions

What is an AI hero image generator?
A tool that generates the large banner image at the top of a website or landing page from a text description. In Gixo Prism it is one channel of the Campaign kit: the kit makes a picture from your topic or document, or uses your photo, cuts it to a 1536×1024 hero banner, and sets your headline on it, spelled as you typed it, so the banner is cut for a hero section rather than left as a generic square image.
What size should a website hero image be?
Landscape, wide enough to span the viewport — Gixo cuts hero banners to 1536×1024, which scales cleanly across common hero-section layouts. Matching email headers in the same kit are cut wider (2048×1024) because email hero sections crop differently.
Can it match my brand colors?
Yes, from the Professional plan up: the kit's designs are built on your Brand Kit (your saved colours, fonts, and logo). On every plan, one design is applied to every image in a kit, so a hero banner, email header, and display ad produced together stay consistent as a set.
How much does it cost?
Hero banners are part of Gixo Prism, from $10/month — the Campaign kit, the deterministic chart/diagram/flowchart/card makers, and AI infographics. Making a kit's picture and captions uses plan capacity. There's a 14-day free trial with no credit card.
Is the output exact like Prism's charts?
No — and that's deliberate. The picture in a hero banner is AI-generated imagery reviewed by you; it sets a scene. The headline on it is set by Prism's renderer, so it is spelled as you typed it, but that is not a data claim. Prism's deterministic makers are the opposite: no AI at render time, so data and labels render exactly. Use each for what it's for.
Can it make banner ads as well as website banners?
Yes. Banner ad is one of the Campaign kit channels, off by default: choose it alongside Website banner and the kit cuts the same picture to 728×90, with your headline and supporting line set on it. Banner channels take no caption, because the words are on the image. Download each banner as PNG, JPG, and WebP. Prism makes the banners; it does not post or run them for you.
