When to Create OG Images

01

Blog post share images

Sharing a blog post without an OG image shows a plain link. Adding a 1200Γ—630 image with the title and key visual can dramatically increase click-through rates.

02

Product pages for e-commerce

When a product URL is shared on KakaoTalk or Slack, a polished product image increases purchase conversions. Prepare images in the optimal size for each platform in advance.

03

Event and promotion campaigns

A standout OG image on a time-limited event URL can make a real difference in participation rates. Create images for X Cards and more, then distribute across multiple channels at once.

Frequently Asked Questions

What is an OG Image (Open Graph Image)?

An OG image is the preview image that appears when a web link is shared on social media (Facebook, Slack, etc.). It's specified using the og:image meta tag in HTML, with a recommended size of 1200Γ—630 pixels. A well-crafted OG image can significantly increase click-through rates.

What are the recommended social image sizes?

Recommended sizes by platform: OG Image (Facebook, Slack, LinkedIn) 1200Γ—630, X Summary Card 800Γ—418, X Large Card 1200Γ—628. IMGLOO generates all sizes at once.

How do I set a preview image for social sharing?

Add an og:image meta tag to your HTML <head>: <meta property="og:image" content="image-url" />. Use 1200Γ—630 images for best results. IMGLOO lets you create properly sized images instantly.

My OG image isn't updating on social media

Social platforms cache OG images after the first crawl. If the preview doesn't update after you replace the image, clear the cache using Facebook Sharing Debugger or Kakao Developer Tools. For X (Twitter), request a re-crawl via Card Validator.

Should I use JPG or PNG?

Most social platforms recommend JPG. It loads faster and offers the widest compatibility. Choose PNG only when you need a transparent background, such as for logos. WebP may not be supported on some platforms yet.
