Facebook Post & Link Thumbnail Generator with AI (1200×630)
Generate 1200×630 Facebook feed and Open Graph link thumbnails with AI. Upload a photo, describe your idea, export PNG, JPG or WebP for free.
1200×630 is the sweet spot for Facebook — it's also the standard Open Graph size, so the same image works as a link-share preview across Facebook, Messenger, and Slack. Use the AI generator to produce a clean, on-brand horizontal composition that reads well in the feed.
Step-by-step
- Upload one or two reference photos.
- Pick the Facebook preset (1200×630).
- Prompt: ‘product on left third, warm gradient background, room for headline on right’.
- Generate, add a headline that mirrors your post copy.
- Add a logo in a corner.
- Export PNG for graphics, JPG for photo-heavy composites.
OG-friendly tips
- Facebook trims the outer edges in some placements — keep text inside the middle 90%.
- The same 1200×630 image can be set as the og:image on your website.
- Under 300 KB is a safe target — use the Compress tool after export.
