Templates

Every template renders in all five sizes and takes your brand colors, font and logo.

**Quote card** — A big quote with attribution. Good for thought leadership and customer voice.

**Blog post announcement** — "New on the blog" card with title, excerpt and a call to action.

**Product promo** — Product shot with name, price, old price and a discount badge.

**Testimonial** — Customer review with star rating, name and photo.

**Carousel slide** — One slide of a series: number, heading and body in a consistent style.

**Event / webinar** — Event announcement with date, time and speaker.

**Big number** — One striking number with a short explanation.

**Tips / list** — Heading with 1–5 numbered or bulleted points.

**We're hiring** — Job announcement with role, location, type and salary.

**Article cover / OG image** — Cover for articles and link previews: title, category, author and date.

How it works

1. Get a key

2. Send one request

Template, size and params as JSON. From curl, n8n, Make, Zapier or your code.

3. Get an image URL

A PNG on a fast CDN in under a second. Batches of hundreds take minutes.

curl -X POST https://api.bannergen.com/v1/renders \
  -H "Authorization: Bearer $BANNERGEN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "template": "quote-card",
  "format": "square",
  "params": {
    "quote": "Simplicity is not the absence of clutter, it is the presence of clarity."
  }
}'

FAQ

What counts as a render?

One successful image is one credit. Failed renders and playground previews are free.

Do I need a card for the trial?

No. Sign up with Google or email and get 50 free renders and an API key right away.

Can I use my own design?

On Pro and Business we turn your design into a template for you within 48 hours. Every template takes your colors, font, logo and handle.

Which sizes are supported?

Square 1080×1080, portrait 1080×1350, story 1080×1920, landscape 1200×628 and Pinterest 1000×1500, all from the same template.

Does it work with n8n, Make or Zapier?

Yes: it's one HTTP call that returns an image URL, so any HTTP step works. A native n8n node is planned.

How long are images kept?

Image links stay live while your account is active. Download them if you need a permanent copy.
