Resize Image to 1200×630 (Facebook / Open Graph Share)

Resize Image to 1200×630 (Facebook Post & OG Image)

1200×630 is the 1.91:1 size that powers link-share previews — it's the recommended og:image dimension, so it's the picture that shows up when your page is posted to Facebook, LinkedIn, Slack or almost anywhere a URL unfurls into a card. Get it wrong and the platform either crops your image to fit the card or falls back to a tiny thumbnail; get it right and every share of your link carries a full-width, on-brand banner. This tool sizes your share image to exactly 1200×630 on your device, so a preview graphic for an unpublished page never leaves your machine.

Good to know

Outputs exactly 1200 × 630 pixels — the recommended size for an Open Graph (og:image) link-preview image.

This is the ratio Facebook, LinkedIn and most link-unfurlers use, so one image covers link shares across platforms.

1200×630 comfortably clears the 600×315 minimum below which platforms may show only a small thumbnail.

"Cover" fit fills the 1.91:1 card and trims overflow, so there are no letterbox bars in the preview.

Keep headline text away from the extreme edges, since some cards crop a few pixels of margin.

Frequently Asked Questions

What is the best size for an Open Graph / Facebook share image? ▼

1200×630 pixels (a 1.91:1 ratio) is the widely recommended og:image size. It renders as a full-width preview card when your link is shared on Facebook and most other platforms that read Open Graph tags, rather than being shrunk to a small thumbnail.

What's the difference between a 1200×630 post image and a 1080×1080 post? ▼

1080×1080 is a square image you upload directly into a feed. 1200×630 is a landscape image referenced by your page's og:image tag — it's the preview that appears when someone pastes your URL. If your goal is a good-looking link share, 1200×630 is the one to use.

Why does my shared link only show a tiny thumbnail? ▼

That usually means the image is below the minimum a platform will render large — around 600×315 — or the og:image tag is missing or points at the wrong file. Supplying a 1200×630 image and referencing it correctly makes the platform show the full-size preview card.

Is my image uploaded to resize it? ▼

No. The canvas resize happens in your browser, so your share graphic never leaves your device.
