OG Image Preview – Test How Your Links Look on Social Media
By RapidTool Team · Last updated: September 2026
When someone shares your URL on a social network, platforms use Open Graph (OG) meta tags to generate a rich link preview card — showing your title, description, and image. Our free OG image preview tool shows you exactly how your page will appear across Facebook, Twitter/X, LinkedIn, WhatsApp, and Slack, so you can fix issues before publishing.

Open Graph Image Specifications
The recommended OG image size is 1200×630 pixels (1.91:1 ratio). Facebook minimum is 200×200px. Use JPG or PNG — JPG is better for photographs, PNG for graphics with text. Keep file size under 8MB for Facebook and 5MB for Twitter/X. Always use absolute URLs (starting with https://) for og:image, not relative paths.
Frequently Asked Questions
Why doesn't my OG image appear when I share my link?
Common causes: the og:image URL returns a 404 error, the image is too small (under 200×200px for Facebook), og:image is missing entirely, or the platform has cached an old version of your page. Use Facebook's Sharing Debugger (developers.facebook.com/tools/debug) to force a cache refresh and see detailed error messages for your specific URL.
What is the ideal OG title length for social media?
Facebook and LinkedIn display approximately 88–100 characters before truncating. Twitter/X shows around 70 characters in the card title. Keep your og:title between 60–70 characters to display cleanly across all platforms. Note that og:title can differ from your page's HTML <title> tag — use og:title for a more compelling social hook.
Can I use different images for Facebook and Twitter?
Yes. Use the og:image tag for Facebook, LinkedIn, and WhatsApp (1200×630px). Add a separate twitter:image tag for Twitter/X — Twitter recommends 1200×600px for summary_large_image cards. This lets you optimize image composition for each platform's display format.
How do I force social networks to refresh the OG image cache?
Each platform has its own cache refresh tool: Facebook has the Sharing Debugger, LinkedIn has the Post Inspector (linkedin.com/post-inspector), Twitter has the Card Validator, and Pinterest has the Rich Pins Validator. After updating your OG tags, run your URL through these tools to force an immediate re-crawl and cache clear.
Does having Open Graph tags improve SEO?
OG tags don't directly affect Google search rankings, but they have significant indirect impact. Better social media previews lead to more shares, higher click-through rates from social posts, and more inbound links — all of which send positive signals to search engines. Think of OG tags as essential for maximizing the reach of every piece of content you publish.
