Generate Open Graph Images via API

Design your OG template once. RenderStack renders a unique, on-brand social card for every page — automatically, via a single API call or embeddable GET URL.

The Problem with Manual OG Images

Every page on your site needs a unique Open Graph image for social sharing. Designing each one by hand is tedious, inconsistent, and impossible to maintain at scale. Most teams either skip OG images entirely — losing click-through rates — or use a single generic image across every page, which looks lazy and hurts engagement. Headless browser solutions like Puppeteer add DevOps overhead, unpredictable rendering, and slow generation times. You need a reliable, fast, and visually precise way to generate social cards programmatically.

Before RenderStack

Manual design for every page variation
Inconsistent branding across social cards
Hours spent per batch of images
Puppeteer infrastructure and maintenance
No OG images on most pages

With RenderStack

One template, unlimited renders
Pixel-perfect branding every time
Milliseconds per image via API
Zero browser infrastructure needed
Every page gets a unique social card

How It Works

Design Your Template

Use the visual drag-and-drop editor to create your OG image layout. Add text, images, shapes, and branding elements exactly how you want them.

Mark Dynamic Layers

Select any element and mark it as a dynamic layer. Give it an API name like 'title', 'author', or 'avatar'. These become your API parameters.

Call the API or Embed a URL

Send a POST request with your dynamic data, or construct a GET URL and embed it directly in your HTML meta tags. Every page gets a unique image.

Key Features for OG Image Generation

Auto-Layout Containers

Text reflows automatically when content length varies. Titles of any length look great without manual adjustment.

Fallback Chains

Define what happens when data is missing — fall back to a default value, initials, or hide the element entirely.

GET URL Embedding

Embed a render URL directly in your meta tags. No server-side code required — the image generates on request.

Image Caching

Rendered images are cached automatically. Subsequent requests for the same parameters return instantly.

Embed in Your HTML Meta Tags

html

<!-- Add to your page's <head> -->
<meta property="og:image" content="https://api.renderstack.io/v1/render/og-template?api_key=rs_get_xxx&title.text=My+Page+Title&author.text=Jane+Doe" />
<meta property="og:image:width" content="1200" />
<meta property="og:image:height" content="630" />
