Upload OG-friendly source
Upload a wide source meant for both OG and feed — anything under 600px wide gets downgraded to a small thumbnail card, so 1200px+ is safest.
Facebook Post Image Resize
The recommended 1200×630px (~1.91:1) for Facebook post images is also the Open Graph (og:image) standard, so the same crop powers link previews across Kakao, Discord, Slack, and X summary cards — not just Facebook. Facebook’s own feed accepts 1:1 and 4:5, but link-style posts down-sample anything off the 1.91:1 ratio, dragging click-through. og:image also needs to be at least 600px wide to render as a large card; below that it drops to a small side thumbnail. This tool exports a 1200×630px JPG while previewing the inner 1:1 and 4:5 crops, so a single master image can power OG, feed, and square posts at once.
How to use
Align inside the inner 1:1
Align key elements inside the inner 1:1 area so the same crop also works as a square or 4:5 post.
Avoid domain label and export
Place the brand logo at the top-right or center rather than bottom-right (where the link card sometimes shows the domain label), then export as 1200×630px JPG.
When to use this tool
Because the same 1200×630px asset doubles as your og:image across Kakao, Slack, Discord, and X previews, investing in one good master is usually the fastest way to cut per-channel design requests.

FAQ
Are post images and ad images the same size?
Almost. Ad images use 1200×628px while post images use 1200×630px — a 2px difference. Matching the exact spec minimizes quality loss from recompression.
Does the size change when I upload multiple images to a post?
Yes. Multi-image posts rearrange into a collage layout with the first image displayed larger. For single-image posts, 1200×630px provides the best result.
Should I use the same size for og:image meta tags?
Yes. Using 1200×630px for og:image ensures clean link-share previews. Images narrower than 600px may appear as small thumbnails.
What is the max file size for post images?
You can upload up to 30MB, but a JPG of 1–3MB or less delivers the best balance of loading speed and image quality.
Can I post square (1:1) or portrait (4:5) images in the feed?
Yes, the feed supports 1:1 (1080×1080px) and 4:5 (1080×1350px). However, 1200×630px is best for link-share preview images.
