Crop Image to OG Image (1200×630)

What is an OG image and why 1200×630?

An Open Graph (OG) image is the thumbnail preview that appears when someone shares a link to your webpage on social media. Facebook defined the 1200×630 pixel standard, and it has become the universally supported size across Facebook, X (Twitter), LinkedIn, Slack, Discord, and most messaging apps.

When you share a URL without a properly sized OG image, platforms either show a random cropped version of your page or no preview at all. A correctly sized 1200×630 image ensures your content looks professional in every feed and chat.

How to create an OG image

1. Upload an image or paste from clipboard.
2. The crop area is pre-set to 1200×630 (1.91:1 ratio). Adjust if needed.
3. Choose JPG for smaller file size or PNG for text-heavy images.
4. Click Download to save your OG image.

For best results, keep important content in the center of the image. Some platforms crop the edges slightly on mobile, so avoid placing text or logos near the borders.

OG image best practices

• File size: Keep under 300 KB for fast preview loading. JPG at 85% quality usually works.
• Text overlay: If you add text, use a large font — OG images appear small in mobile feeds.
• Aspect ratio: 1.91:1 (1200×630) is the safest cross-platform ratio.
• Safe zone: Keep important content within the center 80% of the image.
