Turn a blog post into an Open Graph image

Paste the post, not a screenshot

Open MD Publisher and paste the Markdown. The first heading becomes the suggested title. Shorten the description so it still reads when a network truncates it.

Check the card before you publish

The preview image is a same-origin PNG. Change the theme or the author handle and the image updates. If the title wraps to three lines, cut words rather than shrinking the type yourself.

What you download

1. Front matter you can put at the top of the post.
2. JSON-LD for the page.
3. A 1200×630 PNG for the social card.

That download uses the same credit as a PDF or a Word export. The post is not stored as a library item.
