How to use the open graph tester

1

Paste any page URL

The open graph tester fetches the live page and reads its og meta tags and Twitter card tags — exactly like Facebook’s scraper does.

2

See the previews

One og viewer, four renders: Facebook, X, LinkedIn and an open graph whatsapp preview, all from the same tags.

3

Fix what is flagged

Missing og:image, oversized files, http-only URLs, absent twitter:card — each issue listed with the exact tag to add.

Why use this open graph validator

Every platform, one run

An open graph preview for Facebook, X, LinkedIn and WhatsApp side by side — because each renders your card differently.

Image verification built in

The open graph image tester actually fetches your og:image and reports status, content-type, size and whether it is served over https.

Full tag audit

All og meta tags plus twitter:* tags in one table, with fallbacks shown — a complete open graph validator, not just a picture.

WhatsApp-aware

The open graph whatsapp card is the one everyone forgets — small thumbnail, tight title cut-offs. We render it so you see the crop first.

Debug before you publish

Use it as an open graph debugger after cache-busting changes — see what scrapers get now, not what they cached last week.

Cards drive clicks

Links with a proper image and title earn dramatically more engagement than naked URLs. Thirty seconds in this open graph checker pays for itself.

What is open-graph, and which og meta tags matter

What is open-graph? A small set of meta tags (the Open Graph protocol, created at Facebook) that tells platforms how to unfurl your link into a card: og:title, og:description, og:image and og:url are the big four, with twitter:card as X’s companion tag. They are the difference between a rich open graph social media card and a bare grey link. An og viewer like this open graph checker simply reads those tags from your live HTML and renders each platform’s interpretation.

The failure modes worth testing: an og:image behind a redirect or an http URL (many platforms refuse it), images over ~5 MB (skipped), a missing twitter:card (X falls back to a small summary), and stale scraper caches after a redesign. Run this open graph image tester before big launches, treat it as your open graph validator on every template change, and use it as an open graph debugger when a share looks wrong — then re-check the open graph preview after each fix. An open graph social media card breaks silently, and the open graph whatsapp variant breaks first.

What users say about the open graph checker

The WhatsApp preview alone is worth it — our titles were truncating at the worst possible word and nobody noticed for months.
Laura B. · Social media manager
Caught an og:image serving over http that LinkedIn silently rejected. One tag change, cards everywhere again.
Ahmed Z. · Newsletter operator
Side-by-side platform renders beat opening four different official debuggers. Would love bulk mode someday.
Katie M. · Product marketer
My default open graph validator now. The image fetch check (status, size, https) is more thorough than the platform tools.

Open graph tester FAQs

What is open-graph in plain words?+

A standard set of meta tags that tells Facebook, X, LinkedIn and WhatsApp what title, description and image to show when someone shares your link. Without them, platforms guess — usually badly.

Which og meta tags does the checker read?+

og:title, og:description, og:image (plus width/height/alt), og:url, og:type, og:site_name and og:locale, alongside twitter:card, twitter:title, twitter:description and twitter:image — with page-title fallbacks shown where tags are missing.

Why does my open graph preview differ between platforms?+

Each platform crops differently and caches aggressively: X needs twitter:card for large images, LinkedIn re-scrapes rarely, and the open graph whatsapp thumbnail is tiny. That is why this og viewer renders all four side by side.

What size should my og:image be?+

1200×630 px is the safe universal size (1.91:1), under ~2 MB, served over https at a stable URL. The open graph image tester here verifies status, type and size for you.

A platform still shows my old card — how do I force a refresh?+

Platforms cache scrapes. After fixing tags, re-share with a query string (?v=2) or use the platform’s own open graph debugger to re-scrape — but confirm the new tags in this open graph checker first so you only cache-bust once.
