Finds og:image and resolves relative image URLs.
Copy
Checks dedicated OG copy and ordinary metadata fallbacks.
Dimensions
Reads declared width and height against the 1200 x 630 target.
Accessibility
Looks for useful alt text attached to the shared image.
Common questions
The short version.
What is an OG image?
It is the image websites declare with the og:image meta tag. Social networks, chat apps, and search products use it when they build a preview for a shared URL.
Why does my preview still show an old image?
Most platforms cache link previews. Fixing the tag is only the first step. You may also need to ask LinkedIn, Facebook, or another platform to scrape the URL again.
What size should an OG image be?
1200 x 630 pixels is the safest general-purpose size. It produces a 1.91:1 image that works well across the major large-card previews.
