Resize an image to 1200 × 630 for link previews

1200 × 630 is the size of the picture that appears when a link is shared on Facebook, LinkedIn, Slack, Discord, iMessage and most other places that unfurl a URL. The editor above makes any image exactly that size: crop it with a frame you can drag, or fit the whole image on a coloured background.

Link preview sizes, checked October 2026

The preview image is whatever a page names in its og:image tag, from the Open Graph protocol. Each platform publishes its own rules for it:

Platform	Size	Shape	Limits
Facebook	1200 × 630 or larger	1.91:1	At least 200 × 200; 8 MB
LinkedIn	1200 × 627 at least	1.91:1	5 MB
X, large card	1200 × 600	2:1	At least 300 × 157; under 5 MB

Facebook’s wording is “at least 1200 x 630 pixels for the best display on high resolution devices”, and its advice on shape is to stay “as close to 1.91:1 aspect ratio as possible to display the full image in Feed without any cropping.” The X figures are from X’s card documentation as quoted on its developer forum; its documentation site was not reachable when we checked.

One image for every platform

You do not need three images. 1200 × 630 and LinkedIn’s 1200 × 627 differ by three pixels, half a percent, which LinkedIn absorbs by scaling. X is the odd one out: its card is 2:1, so a 1200 × 630 image shown there loses 30 pixels of height, about 15 at the top and 15 at the bottom.

So make one 1200 × 630 image and keep text and faces at least 20 pixels in from the top and bottom edges. It then survives every crop above intact. The other two sizes are in the editor’s size list for when a single platform is all that matters.

Getting a picture to 1.91:1

1.91:1 is wider than any camera. A 3:2 photo cropped to it keeps 79% of its area, a 4:3 phone photo 70%, and an upright phone photo only 39%. When the frame opens, drag it to the band of the picture that matters, then Apply crop.

For a logo, a book cover or a portrait, choose Fit the whole image, with padding instead. The picture is centred at full height and the sides are filled with a colour; pick the one from your brand and the result reads as a designed card rather than a cropped photo. Padding also makes the file small: our sample padded measured 99 KB as WebP against 158 KB cropped.

The tags that point at it

Save the image, put it on your site, and name it in the page’s <head>:

<meta property="og:image" content="https://example.com/share.jpg">
<meta property="og:image:width" content="1200">
<meta property="og:image:height" content="630">
<meta property="og:image:alt" content="What the image shows">
<meta name="twitter:card" content="summary_large_image">

The URL must be absolute, including https://. Stating the width and height lets a platform lay out the preview before it has downloaded the image. The twitter:card line is what asks X for the large card instead of a small square thumbnail. This site’s own share card is a 1200 × 630 PNG, named exactly this way.

Which format, and how large

The editor exports JPEG at quality 90 on this page, because JPEG and PNG are the formats every link unfurler reads; support for WebP among them is less certain. Measured on our sample landscape at 1200 × 630, the JPEG came to 252 KB, and from the full-resolution camera original 213 KB — well inside every limit above. Choose PNG instead for a card that is mostly flat colour and text.

Changed the image, but the old one still shows?

Platforms fetch a preview once and keep it. After replacing an image, ask them to look again: Facebook’s Sharing Debugger has a Scrape Again button, and LinkedIn’s Post Inspector refetches the page when you inspect it. Giving the new image a new file name works everywhere, because to every cache it is simply a different image.

Questions about 1200 × 630 images

What size should an Open Graph image be?

1200 × 630 pixels, a 1.91:1 shape. Facebook asks for at least that size and LinkedIn for at least 1200 × 627, so one 1200 × 630 image serves both, and X as well.

Why is my link preview cropped on X?

X’s large card is 2:1, slightly wider than 1.91:1, so about 15 pixels are cut from the top and the bottom of a 1200 × 630 image. Keep text 20 pixels in from those edges.

Should a link preview image be JPEG or PNG?

JPEG for photographs, PNG for flat graphics and text. Both are read by every major platform. This page exports JPEG at quality 90, about 250 KB for a detailed photo.

Is my image uploaded to make it?

No. Everything runs in your browser, and the image is saved to your device; it goes online only when you put it on your own site. The privacy policy shows how to check.
