## What is an OG Image Checker?

An **OG Image Checker** (Open Graph Image Checker) is a free tool that previews how your web page appears when shared on social media platforms like [Facebook](https://posteverywhere.ai/facebook-scheduler), [LinkedIn](https://posteverywhere.ai/linkedin-scheduler), [X (Twitter)](https://posteverywhere.ai/blog/how-to-schedule-posts-on-x), Slack, and WhatsApp. It validates your [Open Graph meta tags](https://ogp.me/), [Twitter Card tags](https://developer.x.com/en/docs/twitter-for-websites/cards/overview/abouts-cards), and displays the exact title, description, and preview image that will appear.

Open Graph tags are HTML meta tags created by [Facebook (Meta)](https://developers.facebook.com/docs/sharing/webmasters/) that control how URLs are displayed when shared on social media. Without proper OG tags, your links may show broken images, incorrect titles, or missing descriptions—hurting click-through rates and engagement.

## Open Graph Best Practices for Social Media

- • **LinkedIn:** 1200x627px (1.91:1 ratio) - displays perfectly in feed
- • **X (Twitter):** 1200x675px (16:9 ratio) or 1200x600px (2:1) for Summary Card with Large Image
- • **WhatsApp/Slack:** Use standard 1200x630px OG image

### ✍️ Title & Description Guidelines:

- • **og:title:** 50-60 characters (longer titles get truncated on mobile)
- • **og:description:** 150-155 characters for Facebook/LinkedIn, 200 for X
- • Include your brand name in title for recognition
- • Use action words and clear value propositions
- • Match your actual page content (don't use clickbait)

### 🖼️ Image Optimization Tips:

- • Keep file size under 5MB (under 1MB is ideal for fast loading)
- • Use JPG for photos, PNG for graphics with text
- • Add text overlay for context (make it readable at small sizes)
- • Use high-contrast colors and clear branding
- • Test on mobile - 80%+ of social media is viewed on phones
