Preguntas frecuentes

Is my data safe?
Yes. All processing happens entirely in your browser. Your data never leaves your device and is never uploaded to any server.
Does this tool actually post to social media?
No. It only generates a visual preview in your browser. Nothing is shared, uploaded to social platforms, or sent to any server. You can safely preview before your page is live.
Can I upload an image instead of using a URL?
Yes. Use the upload button to select an image from your device. It is previewed locally using a Base64 data URI — no upload to any server occurs.
Why does my live social card look different from the preview?
Social platforms cache Open Graph metadata, sometimes for 24 hours or more. After updating your meta tags, use the platform's official tools (Facebook Sharing Debugger, Twitter Card Validator) to force a cache refresh and see the updated card.
What image dimensions should I use for social cards?
The recommended size for Twitter, Facebook, and LinkedIn is 1200x630px (1.91:1 aspect ratio). This renders sharply on all device sizes and in all card types. Minimum sizes vary by platform and card type.
Can this tool fetch and analyze any live URL?
Yes. Paste any public URL and click Analyze — the tool fetches the page server-side to read its Open Graph and Twitter Card meta tags, then populates all fields automatically. This bypasses CORS restrictions that would prevent direct browser fetching. No data from the page is stored.
What is the OG Quality Score?
The quality score rates your Open Graph implementation out of 100 points across seven criteria: presence of og:title, og:description, og:image, and twitter:card, plus title length (≤60 chars), description length (≤200 chars), and HTTPS image URL. Failing items show specific tips for how to fix them.
Which platforms does the preview cover?
Twitter/X, Facebook, LinkedIn, Discord, WhatsApp, and Slack. Each tab shows a platform-accurate card mockup matching that platform's real layout and styling.

¿Qué es Open Graph Checker?

Check and preview Open Graph tags for any URL — instantly. Paste any link to fetch and analyze its og:title, og:description, og:image, og:url, twitter:card, and all related meta tags. See realistic platform-accurate card previews for Twitter/X, Facebook, LinkedIn, Discord, WhatsApp, and Slack. Score your OG implementation with a 100-point quality checker that flags missing tags, oversized titles, and insecure image URLs. Also works as a manual editor: fill in fields directly and preview without a live URL. Everything runs in your browser — no sign-up required.

¿Por qué usar Open Graph Checker?

  • Catch problems before publishing — see if your title is too long, your image is the wrong size, or your description is missing before your link goes live.
  • Platform-accurate mockups — different platforms display cards differently. See Twitter, Facebook, and LinkedIn renderings in one place.
  • No social media connection required — preview without logging in, posting, or making your page public.
  • Image upload support — test with a local image without needing a public URL first.
  • Completely private — your page details never leave your browser.

Casos de uso de Open Graph Checker

Pre-publish content check

Before publishing a blog post, article, or landing page, preview how the social card will look to verify title length, description, and image crop.

Marketing campaign preparation

Verify that campaign landing pages will display compelling cards when shared in posts, ads, and email campaigns that drive social traffic.

Open Graph tag implementation testing

After adding og:title, og:description, og:image, and og:url meta tags to a page, confirm the tags produce the expected visual result without waiting for social platform cache updates.

Team review and approval

Share a screenshot of the preview with stakeholders to get approval on social card design before launch.

Consejos y buenas prácticas

  • 💡Twitter summary_large_image cards require an image at least 300x157px. For best results, use 1200x630px images which look sharp on all displays.
  • 💡Facebook and LinkedIn recommend an image ratio of 1.91:1 (1200x630px). Taller images may be cropped depending on the platform context.
  • 💡Keep og:title under 60 characters — longer titles are truncated on most platforms. Your page's HTML <title> is used as a fallback if og:title is missing.
  • 💡Platform caches can hold old versions of your social card for hours. Use Facebook's Sharing Debugger or Twitter's Card Validator to force a cache refresh after updating your tags.

Cómo se compara

Social platforms provide their own official preview tools: Facebook Sharing Debugger, Twitter Card Validator, and LinkedIn Post Inspector. These show the actual fetched metadata and force cache refreshes, but require you to log in and have your page publicly accessible. TinyTool's preview tool works before your page is live, does not require login, and shows all three platforms side by side — making it ideal for pre-launch review and rapid iteration.
