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.
