Meta tags
How it works
Paste the HTML of your page (or just its <head>) and this Open Graph
preview reads every og: and twitter: meta tag with the browser’s
own HTML parser, then draws the link preview cards Facebook, X and LinkedIn would build from
them. Edit any field and the cards, the checklist and the generated meta tags update
instantly, so you can fix a missing og:image or a too-long title before you
publish. The checklist flags the classic problems: missing tags, relative image URLs that
crawlers cannot resolve, and titles over 60 characters that get truncated.
Everything happens in your browser — your HTML is never uploaded and no crawler is called,
so you can test staging pages, intranet pages and unpublished drafts that a server-side
debugger could never reach. The og:image is not fetched unless you tick the box, keeping
the page fully offline by default. Aim for a 1200×630 pixel image (1.91:1) under 5 MB
and an absolute https:// URL for the widest platform support.
Frequently asked questions
How do I test my Open Graph tags without publishing the page?
Paste the page's HTML (or just its <head>) into the box at the top — the tool reads every og: and twitter: meta tag with the browser's own HTML parser and draws the preview cards. Because nothing is fetched from a server, it works on localhost, staging sites, intranet pages and unpublished drafts that the Facebook Sharing Debugger or LinkedIn Post Inspector cannot reach.
What size should an og:image be?
1200 × 630 pixels (a 1.91:1 ratio) is the safe size for Facebook, LinkedIn and X's summary_large_image card. Keep the file under about 5 MB, use PNG or JPG, and always give an absolute https:// URL — crawlers cannot resolve a relative path like /images/card.png, which is the single most common reason a preview shows no thumbnail.
Why is my link preview not showing an image on Facebook or LinkedIn?
Usually one of three things: og:image is missing, it is a relative URL, or the image is behind a login or a robots.txt block. This tool's checklist flags the first two instantly. If your tags look correct but the old preview still appears, the platform has cached it — re-scrape the URL in Facebook's Sharing Debugger or LinkedIn's Post Inspector to refresh the cache.
