how to generate open graph images automatically per post

TL;DR

Posts with proper OG images get meaningfully more clicks from social and chat unfurls. A template plus the post title beats hand-designing every image. Applies to blogs, docs sites, and any site with per-page meta tags.

The query

how to generate open graph images automatically per post

Use this when

• You publish articles or pages at volume.
• Social and chat unfurls matter for your distribution.
• You have or can design one brand template.

Not for

• You publish rarely (make the few images by hand).
• The platform overrides OG tags with its own cards (check with the debugger first).
• You have no consistent brand template (design one first; automation needs a template).

Steps

1. Design one template: background, logo placement, title text area, and a readable font size. Expected output: A single template that fits titles from 20 to 120 characters.

2. Hook generation into the publish flow: title in, PNG out, saved next to the post. Expected output: An image file generated automatically for every new post.

3. Set the og:image and twitter:image meta tags to the generated file's URL. Expected output: Meta tags pointing at the per-post image.

4. Validate with a social card debugger and fix text overflow on long titles. Expected output: Clean card previews with no clipped text.
