Platform Details
Facebook & Meta Platforms
Facebook uses the same og:image for Instagram link previews and WhatsApp link sharing. Images are displayed at a 1.91:1 ratio in the feed.
- Recommended: 1200 x 630 px
- Images smaller than 600x315 show as small thumbnails instead of large cards
- Facebook caches images aggressively — use the Sharing Debugger to refresh
- Supported formats: JPEG, PNG, GIF, WebP
Twitter / X
Twitter supports two card types with images. The summary_large_image card shows a large banner image; summary shows a small square thumbnail.
- summary_large_image: 1200 x 630 px (1.91:1)
- summary (small card): 240 x 240 px minimum, displayed as 120x120
- Twitter will fall back to og:image if twitter:image is not set
- Max file size: 5 MB. Images larger than 4096x4096 are ignored.
LinkedIn is strict about image sizes. Under-sized images won't display as large cards.
- Recommended: 1200 x 627 px
- Images must be at least 1200px wide for the large card format
- Use the Post Inspector to test and clear cache
Discord
Discord shows link previews in an embed card with a colored sidebar. It reads og:image, og:title, og:description, and og:site_name.
- Large images: 1200 x 630 px (shown below the text)
- Small thumbnails: If the image is square or small, Discord shows it as a thumbnail on the right side
- Animated GIFs are supported
Safe Zone Guidelines
Different platforms crop images slightly differently. To ensure your key content is always visible, keep important elements within the safe zone:
- Keep text and logos within the center 80% of the image (approximately 960 x 504 px)
- Avoid placing critical text in the bottom 60px — some platforms overlay the domain or a play button
- Leave at least 40px padding on all sides
- Use high contrast text — images are often seen on small screens in bright sunlight
File Format Recommendations
PNG
Best for text-heavy images and graphics with sharp edges.
- Lossless quality
- Larger file size (200-800 KB typical)
- Supports transparency (but most platforms ignore it)
JPEG
Best for photographs and images with gradients.
- Smaller file size (50-300 KB typical)
- Some quality loss at high compression
- Faster loading — better for performance
WebP
Modern format with best size-to-quality ratio.
- 30-50% smaller than PNG/JPEG
- Supported by most platforms now
- Some older scrapers may not support it — provide a fallback
