# Generate an OG image with HTML-to-image
infsh app run infsh/html-to-image --input '{
  "html": "<div style=\"width:1200px;height:630px;background:linear-gradient(135deg,#1a1a2e,#16213e);display:flex;align-items:center;padding:60px;font-family:system-ui;color:white\"><div><h1 style=\"font-size:56px;margin:0;line-height:1.2\">How We Reduced Build Times by 80%</h1><p style=\"font-size:24px;opacity:0.8;margin-top:20px\">engineering.yourcompany.com</p></div></div>"

• 40px minimum padding from all edges
• Some platforms crop edges or add rounded corners
• Never put critical text in the outer 5%

Colors

Dark backgrounds outperform light in social feeds — most feeds have white/light backgrounds, so dark OG images pop.

infsh app run falai/flux-dev-lora --input '{
  "prompt": "clean professional social sharing card, dark gradient background, abstract geometric shapes, modern tech aesthetic, minimal, no text, 1200x630 equivalent aspect ratio",
  "width": 1200,
  "height": 630
}'

OG Meta Tags Reference

<!-- Essential (Facebook, LinkedIn, Discord, Slack) -->
<meta property="og:title" content="Title here (60 chars max)" />
<meta property="og:description" content="Description (155 chars max)" />
<meta property="og:image" content="https://yoursite.com/og-image.png" />
<meta property="og:url" content="https://yoursite.com/page" />
<meta property="og:type" content="article" />

<!-- Twitter/X specific -->
<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:title" content="Title here" />
<meta name="twitter:description" content="Description" />
<meta name="twitter:image" content="https://yoursite.com/og-image.png" />

<!-- Image dimensions (optional but recommended) -->
<meta property="og:image:width" content="1200" />
<meta property="og:image:height" content="630" />

Twitter Card Types

Always use summary_large_image unless you have a specific reason not to — the large image gets significantly more clicks.

Consistency System

For a blog or site with many pages, create a template system:

Testing OG Images

# Research OG debugging tools
infsh app run tavily/search-assistant --input '{
  "query": "open graph image debugger preview tool test og:image"
}'
