Free OG Image Generator — Create Open Graph Images for Social Sharing
Last Updated: May 2026 · 5 min read
Every time someone shares your blog post, article, or product page on Twitter, LinkedIn, Facebook, or Slack, the platform fetches your Open Graph image to display as a preview. Without an OG image, platforms show a blank gray box — or nothing at all. Our free OG image generator lets you create professional 1200×630 px preview images in seconds. No design skills, no Canva account, no signup.
What Is an Open Graph Image?
Open Graph (OG) is a protocol created by Facebook (now Meta) in 2010 that defines how URLs are displayed when shared on social platforms. The OG image is the preview thumbnail that appears in link cards across:
- Facebook / Instagram: Link preview cards
- Twitter / X: Twitter Cards
- LinkedIn: Article preview thumbnails
- Slack: Link unfurling previews
- WhatsApp: Link preview images
- Discord: Embed previews
- iMessage: Link previews on iOS
Without a proper OG image, you're leaving engagement on the table. Posts with compelling images get 2–3× more clicks than posts without.

OG Image Design Best Practices
1. Keep text short and scannable
OG images are displayed at thumbnail size (often 300–400 px wide). Long titles get hard to read. Aim for 5–8 words for the title, 10–15 for the description.
2. Use high contrast
Dark text on light backgrounds and light text on dark backgrounds both work. Avoid mid-gray text on mid-gray backgrounds — it disappears on small screens.
3. Include your brand
Add your domain or logo to every OG image. When someone scrolls past your shared link, they should recognize it as yours.
4. Be consistent
Use the same template across all posts. Consistency builds brand recognition and signals quality.
5. Match the content type
- Tutorial → use a tag pill saying "Tutorial" or "Free Guide"
- Product announcement → focus on the product name and key benefit
- Blog post → emphasize the headline and your domain
6. Test before publishing
After setting your OG tags, test with: - Facebook Sharing Debugger - Twitter Card Validator - LinkedIn Post Inspector - OpenGraph.xyz

Frequently Asked Questions
What is an OG image? An OG image (Open Graph image) is the preview thumbnail shown when your URL is shared on social media — Facebook, LinkedIn, WhatsApp, Twitter/X. It is defined by the og:image meta tag in your HTML head section.
What is the ideal OG image size? The recommended size is 1200×630 pixels at 72 DPI. Minimum is 600×315px. For Twitter/X summary cards, 1200×628px is optimal. Keep text and logo centered with at least 80px padding from edges to avoid cropping.
How do I add an OG image to my website? Add this inside your HTML head: and . Use absolute URLs, not relative paths.
Do I need separate images for Facebook and Twitter? Not necessarily — a 1200×630px image works for both. Twitter may display it slightly differently depending on the card type. Test with the Twitter Card Validator and Facebook Sharing Debugger after publishing.
