Preview how images will look when shared on Facebook, Twitter, and LinkedIn.
Sharing a link posts more than the link: each network builds a card from your image and text, and each one crops your image differently. This tool renders that card the way the platform will, with the image cropped to the network's banner ratio and the title and description laid out beneath it, so you judge the image as shared rather than as designed. What most people get wrong: a square or portrait image silently loses its top and bottom, and any text placed near the edges of the artwork disappears before anyone sees the post.
A concrete input and expected output from the current implementation.
Input
A 1080 x 1080 px square photo of a hiking trail with the words '10 FALL HIKES' near its top edge, shared with the title '10 fall hikes for beginners' and a three-sentence description.
Expected output
Three preview cards. Facebook and LinkedIn show the photo center-cropped to a 1.91:1 banner: a 1080 x 565 px band across the middle, with roughly 257 px removed from the top and bottom, so the '10 FALL HIKES' text near the top edge is cropped out. The title fits on one line; the description wraps and is cut off with an ellipsis. X renders the same photo in a wide-format large-image card (recommended 1200 x 675 px), where the square is cropped even harder.
A 1.91:1 crop of a 1080 px square leaves 1080 / 1.91 = 565 px of height, so (1080 - 565) / 2 = 257 px is trimmed from both top and bottom. The preview makes that arithmetic visible before you publish.
You provide the image plus the title and description the post will carry. The tool composes a share card in each network's layout, with the image at the top and the site name, title, and description beneath it, and displays the image at the ratio that network uses for its card. The crop and text wrap you see in the preview are the ones the network applies, not your file's original framing.
The crop is the platforms' rule, not the tool's. Facebook and LinkedIn display the shared image as a banner near 1.91:1 and trim from the center of the file to reach that ratio; X builds its large card from Twitter Card markup with a wider recommended frame. Anything outside the center band, such as headlines along the top or bottom edge, is removed before the card renders.
Mostly, but not for final sign-off. The preview applies each network's current crop and layout rules to your image and text, and networks do change those rules and render slightly differently by device and app. When exact appearance matters, share the real URL and inspect the live post, or run the URL through the network's own debugger.
Match the network's recommended ratio. Facebook and LinkedIn banners are built around 1200 x 630 px, about 1.91:1, and X's large-image card around 1200 x 675 px, which is 16:9. An image already in that ratio for the platform you care about should render uncropped; anything taller or squarer gets center-cropped.
