Open Graph Image Guide

A good og:image makes shared links look intentional. This guide covers the practical requirements and the usual mistakes.

Requirements

  • Absolute https URL that returns 200.
  • A stable, cacheable path (not a one-off signed URL).
  • A wide aspect ratio commonly used for summary_large_image cards.

Common mistakes

  • Relative og:image path.
  • Image behind auth or that 404s.
  • No og:image at all → poor preview.

Preview

Use the Open Graph Preview (it shows the image URL as text — it never downloads remote images). Background: improving Open Graph metadata.

FAQ

Does the tool fetch my image?

No. By design it shows the URL as text and performs no remote fetch.

Exact pixel size?

Use a wide, large image; exact requirements vary by platform — treat as guidance.
