Meta Image Best Practices
Optimal Image Sizes
Use 1200x630px as your default meta image size. This works well for most platforms including Facebook, LinkedIn, and Twitter. For X (Twitter), keep important content away from the bottom-left corner where the domain overlay appears.
File Format & Size
Use JPEG for photographs and PNG for graphics with text. Keep file sizes under 1MB for faster loading. Compress images without sacrificing quality to improve performance.
Text & Branding
Include your logo and keep text minimal - it should be readable even at smaller sizes. Use high contrast colors and avoid placing important elements near edges.
Testing & Validation
Always test your meta images across different devices and platforms. Use social media debuggers to verify how your images appear and clear caches when updating.

A meta image is the preview image shown when your page is shared on social media or messaging apps. It's defined with Open Graph tags (og:image) and Twitter Card tags (twitter:image) in your page's HTML head. Without one, platforms show a bare link or pick a random image from your page.
1200×630 pixels (1.91:1) is the safest default — it works well on Facebook, LinkedIn, WhatsApp, and Slack. Twitter/X prefers 1200×675 (16:9) for large summary cards. Keep files under 1MB and important content away from the edges.
og:image is the Open Graph standard used by Facebook, LinkedIn, WhatsApp, Slack, and most platforms. twitter:image is Twitter/X's own tag that overrides og:image on that platform. Setting both gives you full control over how previews render everywhere.
Platforms cache meta images aggressively. After changing your image, use each platform's debugger — like Facebook's Sharing Debugger or LinkedIn's Post Inspector — to force a re-scrape. Adding a query string to the image URL also busts the cache.
Meta images don't directly change rankings, but they significantly boost click-through rates when your content is shared. Complete, well-structured metadata also helps AI crawlers and search engines understand and present your pages correctly.
