Open Graph & OG Tags Social Preview Checker

Open Graph & Social Preview Checker is a bulk OG tags checker and link preview checker. For any list of URLs it reads the Open Graph and Twitter Card tags, then downloads the preview image and measures its real pixel size and file size. You get a pass or fail for Facebook, LinkedIn, X, Slack, Discord and WhatsApp, plus a fix list. It catches images that are too small, broken or the wrong shape, not just the size the page claims.

Pricing: pay per result: $2.00 per 1,000 results ($0.20 per 100, $20.00 per 10,000), plus $0.00005 per run start. One result = one URL checked.

What data you get (one row per URL)

Field	What it is
url, statusCode	The page and its HTTP status
og	Open Graph tags: title, description, image, url, type, siteName, declared width and height
twitter	Twitter Card tags: card, title, description, image, site
pageTitle, metaDescription	The page's own title and meta description
image	The preview image as actually downloaded: url, statusCode, bytes, contentType, real width, height and ratio
platforms	pass or fail for facebook, linkedin, twitter, slack, discord, whatsapp
issues, issueCount	Plain-English fix list
goodPreview	true when no issues were found

What it checks

• Missing og:title, og:description, og:image or og:url
• Missing twitter:card (X then falls back to a small preview)
• Preview image tiny (under 200×200), or below the recommended 1200×630
• Preview image larger than 8 MB (Facebook may skip it)
• og:image that cannot be read (broken URL, blocked, or unsupported format)

Platform verdicts:

Platform	Pass when
Facebook, LinkedIn	Title, description and image present, and the real image is at least 600×315
X / Twitter	A card (or the core OG tags) plus an image
Slack, Discord, WhatsApp	A title and an image

How to use it

1. Paste your URLs into URLs to check.
2. Leave Fetch and measure the preview image on (the default) to get real image sizes.
3. Click Start, then filter on goodPreview = false for your fix list.

FAQ

Why download the image instead of reading og:image:width? Declared sizes are often missing or wrong. The real pixel size decides whether a network shows a large card or a small thumbnail.

Does it clear the Facebook or LinkedIn cache? No. It shows what your tags say now. If a network still shows an old preview, use that network's own debugger to refresh it.

Does it render JavaScript? No. It reads the HTML the server returns, which is what the social networks' crawlers read too.

Are the platform rules official? They are our own checklist, based on each network's published image guidance and listed above, so you can see exactly why a URL failed. Networks change their rules, so treat a fail as a strong hint rather than a guarantee.

Is it legal? It reads public pages and their public preview images, the same as a browser. Only check sites you have the right to access.
