Link Preview Checker — Free Tool
See how your link will look before you share it. Paste a URL to preview the card on Facebook, LinkedIn, and X, and get a list of the Open Graph tags that are missing, too long, or served over http.
The page is fetched by BulkPublish's servers, not by your browser. Only public pages can be read — logged-in, password-protected, and intranet URLs will not work.
Features
- One paste, three previews — Facebook, LinkedIn, and X side by side
- Respects twitter:card, so you see the wide image or the small thumbnail exactly as X will show it
- An audit of every card tag: missing title, over-long description, http image, no site name
- Follows redirects and shows the URL the card was actually read from
- No sign-up — the page is fetched by our servers, so CORS never gets in the way
Frequently asked questions
Why does the old preview still show after I fixed the page?
Every platform caches what it scraped, sometimes for days, so your fix stays invisible until it reads the page again. Force it with the platform's own debugger: the Facebook Sharing Debugger, the LinkedIn Post Inspector, or the X Card Validator. This tool always reads the page live, so if it shows the new card and the platform does not, caching is the answer.
Can I check a page that needs a login?
No. The page is fetched by our servers, which are not signed in to anything, so pages behind a login, a staging password, or a company intranet cannot be read. Only publicly reachable http and https pages work.
What image size should I use for og:image?
1200 × 630 pixels is the safe default — the 1.91:1 ratio that Facebook, LinkedIn, and X's summary_large_image all expect. Keep the file under about 5 MB, serve it from an absolute https URL, and keep text away from the edges, since each platform crops slightly differently.
Which tags does the checker read?
og:title, og:description, og:image, og:site_name, and og:type, falling back to twitter:title, twitter:description, and twitter:image where the Open Graph tag is missing, plus the page's own title element and twitter:card. That is the same set the platforms read.
Are the previews pixel-exact?
They are a close approximation: image placement, field order, and which fields appear at all. Exact fonts, spacing, and truncation shift between each platform's website and its mobile apps, so treat the previews as a reliable guide to structure rather than a screenshot.
