Why Open Graph Tags Matter
Open Graph tags control how a link looks when it's shared on Facebook, LinkedIn, WhatsApp, and Slack — the title, description, and image that appear in the preview card. Without them, platforms fall back to guessing content from the page, which often means no image, a cut-off title, or the wrong text entirely.
A broken or missing link preview can quietly hurt click-through rates on every post, ad, and shared link — since people are far less likely to click a link with no image or a confusing snippet next to it.
Open Graph vs Twitter Card Tags
Open Graph (og:title, og:description, og:image) is the standard used by Facebook, LinkedIn, WhatsApp, and most other platforms. Twitter/X uses its own twitter:card tags, but automatically falls back to Open Graph tags if Twitter-specific ones are missing — so adding both ensures the best possible preview everywhere, including the larger image layout on X.

Frequently Asked Questions
Is the Open Graph Preview Checker free?
Yes — completely free, unlimited checks, no signup required.
Why do I need to paste HTML instead of entering a URL?
This tool runs entirely in your browser, and browsers block cross-site requests to other domains for security (CORS). Pasting your HTML avoids this limitation and keeps the tool 100% private — nothing is sent to a server.
Where do I get my page's HTML to paste here?
Open your live page, right-click and choose "View Page Source" (or press Ctrl+U), then copy the content inside the <head> tag — or the whole page source, since this tool automatically extracts the relevant tags.
Why is my link preview showing no image on Facebook or WhatsApp?
This almost always means the og:image tag is missing, points to a broken URL, or the image is too small. Most platforms require at least 200×200px, with 1200×630px recommended for the best display.
What is the difference between og:title and twitter:title?
og:title controls previews on Facebook, LinkedIn, WhatsApp, and Slack. twitter:title is used specifically by X/Twitter — if it's missing, Twitter automatically falls back to og:title.
Do I need both Open Graph and Twitter Card tags?
Open Graph tags alone cover most platforms including Twitter/X fallback behavior, but adding twitter:card explicitly ensures the larger "summary_large_image" layout instead of a small thumbnail.
Why does my preview show an old image after I updated og:image?
Most platforms cache link previews. Use each platform's debugging tool (like Facebook Sharing Debugger or LinkedIn Post Inspector) to force a re-scrape after making changes.
Is my pasted HTML uploaded anywhere?
No — parsing happens entirely in your browser using the native DOMParser API. Your HTML is never sent to or stored on any server.
