What is a Dynamic OG Image Generator API?

A dynamic OG image generator API allows you to programmatically create Open Graph images — the preview images that appear when your content is shared on social media platforms like Twitter, Facebook, LinkedIn, and Slack.

Instead of manually designing images for each piece of content, you send a simple API request with your title, description, and styling preferences, and receive a professionally designed image in milliseconds.

⚡ Instant Generation

Generate images in under 100ms. Perfect for dynamic content that changes frequently.

🎨 Full Customization

Control colors, fonts, layouts, and branding. Match your site's design perfectly.

📊 Built for Scale

Handle thousands of requests per minute. Enterprise-ready infrastructure.

How to Use the OG Image Generator API

Generating dynamic OG images is as simple as making a POST request:

// Generate an OG image with a single API call
const response = await fetch('https://ogimageapi.io/api/generate', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'X-API-Key': 'your_api_key'
  },
  body: JSON.stringify({
    title: 'How to Build a SaaS in 2024',
    subtitle: 'A complete guide for developers',
    theme: 'dark'
  })
});

const imageBuffer = await response.arrayBuffer();

Why Use an OG Image API?

1. Increase Social Media Engagement

Posts with custom images get 2-3x more engagement than those with generic previews. Dynamic OG images make every share look professional and branded.

2. Save Development Time

Building an image generation system from scratch takes weeks. With our API, you're generating images in minutes. Focus on your product, not infrastructure.

3. Perfect for Dynamic Content

Blog posts, product pages, user profiles, search results — any page with unique content deserves a unique preview image. Our API makes this trivial.

4. SEO Benefits

Rich social previews increase click-through rates, driving more traffic to your site. More traffic, more backlinks, better rankings.
