Frequently Asked Questions

Everything you need to know about Open Graph tags, our free OG checker, and OG image testing.

What is an Open Graph checker?
An Open Graph checker (also called OG checker, Open Graph tester, or OG debugger) is a free tool that inspects the Open Graph meta tags on any webpage. It shows you how your links will look when shared on social media platforms like Facebook, Twitter/X, LinkedIn, Discord, WhatsApp, and Slack. OpenGraph.to analyzes your og:title, og:description, og:image, and other meta tags, giving you a score and actionable recommendations.
What is an OG image checker?
An OG image checker tests the og:image meta tag on your page: whether the image loads, its dimensions, file size, HTTPS status, and alt text. OpenGraph.to is a free OG image tester that also previews how your image appears on Facebook, Twitter/X, LinkedIn, Discord, and WhatsApp so you can fix crop, size, or loading issues before sharing.
How do I check or test my Open Graph tags?
Paste your URL into the search bar above and click Inspect. Our free Open Graph tester instantly fetches your page, extracts all Open Graph and Twitter Card meta tags, and shows live previews on each social platform. You'll also get a score out of 100 with specific issues and fixes.
What are Open Graph meta tags?
Open Graph meta tags (og: tags) are HTML meta elements that control how your webpage appears when shared on social media. The key tags are og:title (the title shown in previews), og:description (the summary text), og:image (the preview image), and og:url (the canonical URL). They were created by Facebook in 2010 and are now supported by virtually all social platforms.
What is the ideal og:image size?
The recommended og:image size is 1200 x 630 pixels (1.91:1 aspect ratio). This works well across all major platforms including Facebook, Twitter/X, LinkedIn, Discord, and WhatsApp. Keep the file size under 5MB (ideally under 1MB; under 500 KB for WhatsApp) and use JPG for photos or PNG for graphics with text.
How do I fix missing Open Graph tags?
Add the required meta tags inside your HTML head section. The essential tags are: og:title for the title, og:description for the summary, og:image for the preview image (use an absolute HTTPS URL), and og:url for the canonical URL. Use OpenGraph.to to verify your tags after adding them.
What is the difference between Open Graph and Twitter Cards?
Open Graph tags (og:) were created by Facebook and are used by most social platforms. Twitter Cards (twitter:) are Twitter/X-specific tags. Twitter/X will fall back to Open Graph tags if Twitter Card tags are missing, but setting twitter:card explicitly is required to enable rich previews on X. For best results, set both Open Graph and Twitter Card tags.
Is OpenGraph.to free to use?
Yes, OpenGraph.to is a completely free Open Graph checker and OG image tester. You can check unlimited URLs, preview your links on all major social platforms, and get detailed analysis with scores and recommendations — all without creating an account.
