How to make a share image that works everywhere
Why 1200 × 630 pixels
One image can serve LinkedIn, Facebook, and X if you size it for the strictest of them. Meta asks for images of at least 1200 × 630 pixels for the best display on high-resolution screens, and LinkedIn lists 1200 × 627 as its minimum. Both recommend a 1.91:1 shape, which 1200 × 630 matches.
- Meta recommends at least 1200 × 630, and 600 × 315 for the larger link layout. Smaller images show much smaller. Hard limits: at least 200 × 200 pixels and no more than 8 MB.
- LinkedIn lists 1200 × 627 as its minimum and 1.91:1 as its recommended ratio. Images less than 401 pixels wide show as a thumbnail. Hard limit: 5 MB.
- X's large image card uses a 2:1 image between 300 × 157 and 4096 × 4096 pixels, under 5 MB, as a JPG, PNG, WEBP, or GIF. SVG isn't supported.
Design for a small, cropped preview
Feeds show share images at a fraction of their size, so a short headline in large type reads best. Keep your text and logo away from the edges: X's large card shows images at 2:1, so a 1200 × 630 image can lose about 15 pixels at the top and bottom. This tool keeps text inside a 72-pixel margin, and its crop guides show the area X can trim.
Text also needs enough contrast to read. WCAG asks for at least 4.5:1 for normal text and 3:1 for large text. The tool picks dark or white text for your background and warns when contrast falls short, including over a photo, where it measures the pixels behind each line.
Add the image to your page
Upload the image to your site, then point your page's og:image tag at its full address, starting with https://. X reads the same tag when your page has no twitter:image tag.
- Add og:image:width and og:image:height with 1200 and 630. Meta says these let it show the image the first time your link is shared, instead of after it has processed the image.
- Add og:image:alt with a short description of the image for people who can't see it.
- Check the page with the Open Graph preview to see each platform's card and catch missing tags.
Frequently asked
Questions, answered.
What people ask before they use the Social share image maker.
1200 × 630 pixels. It meets Meta's recommendation of at least 1200 × 630 and LinkedIn's minimum of 1200 × 627, and both recommend its 1.91:1 shape. X's large card is 2:1, so it trims a little from the top and bottom.
PNG keeps text and flat colors crisp and is usually small for designs without a photo. With a photo, a JPG is often much smaller. LinkedIn and X accept share images up to 5 MB, and the tool warns if your file is larger.
No. The tool opens your images and draws the share image in your browser, and the download is created there too. Nothing you add is sent to Ampere.
It compares dark and white text against your background color and uses whichever has more contrast. Over a photo, it measures the contrast behind each line of text and warns when parts of it fall below 4.5:1, the minimum WCAG sets for normal text.
X's large link card shows images at 2:1, a little wider than 1200 × 630, so about 15 pixels can come off the top and bottom. Turn on crop guides to see that area, and keep text inside the dashed margin.
Platforms keep a copy of each link preview, and Facebook stores images by their address. Upload the new image under a new file name and update og:image, then enter your page in LinkedIn's Post Inspector and Facebook's Sharing Debugger so they read it again. New posts get the new image; posts shared earlier keep the old one.
