Open Graph is the protocol Facebook, LinkedIn, and most platforms read to build a link preview, using tags like og:title, og:description, and og:image. Twitter (X) uses its own twitter:card tags, where summary_large_image renders the big edge-to-edge graphic instead of a small thumbnail. They overlap heavily — Twitter falls back to Open Graph tags when its own are missing — so in practice you set both for full coverage. The image specs also differ slightly: Twitter's large card is 1200x675, while the Open Graph standard is 1200x630. This generator builds both tag sets from the same title, subtitle, URL, and site name, and re-renders the PNG at each platform's exact size, so paste the matching block into your page's head and you're covered everywhere.

Social platforms cache the preview the first time a URL is shared, so edits to your og:image won't appear until that cache is cleared. The other common cause is that the og:image URL points to a file that isn't publicly reachable — a localhost path, a private bucket, or a page behind login — since the platform's crawler must fetch the image from the open web. Fix it by hosting the downloaded PNG on a live CDN or web host, then updating the og:image and twitter:image URLs in your tags to that public link. After deploying, re-scrape the page in each platform's debugger, such as Facebook's Sharing Debugger, to force a fresh fetch. Design and export your card here, then drop in the generated tags before re-scraping.

Each network crops link previews to its own aspect ratio, so no single file is perfect everywhere. The de facto standard is 1200x630, the Open Graph default, which is safe to reuse across most platforms when you only want one image. For pixel-perfect results, Twitter's large card wants 1200x675, LinkedIn uses 1200x627, and Instagram is a 1080x1080 square. This tool sidesteps the guesswork: switch the preview tab and the card re-renders at that platform's exact dimensions before exporting as a PNG, so text and logos stay sharp and correctly positioned rather than stretched. If you publish to one main channel, export that size; if you syndicate widely, the 1200x630 file is the practical one-size-fits-most choice.

Yes — that is the one manual step. The generator draws and exports the PNG locally in your browser, but social platforms fetch preview images from a live URL, not from your computer. So after downloading, upload the PNG to your own CDN or web host where it has a public, reachable link, then swap that link into the og:image and twitter:image values in the copied meta tags. Hosting it on the same domain as the page is fine and often simplest. Once the file is live and the tags point to it, sharing your URL will pull the image automatically. Design your card here, copy the generated Open Graph and Twitter Card block, and you only need to replace those two image URLs with your hosted file.

Long titles are handled for you so nothing spills off the layout. As you type, the headline wraps automatically onto multiple lines to fit the card width, and if it still overflows the available space it is truncated with an ellipsis rather than running off the edge. That keeps every export clean regardless of how much text you enter. For the strongest preview, aim for a punchy headline — short, scannable lines read better in a crowded feed than a paragraph that gets cut off. You can also drag the title size between 40 and 120 pixels to balance impact against length, and switch font families if a narrower typeface helps more words fit. Type your headline into the live canvas and adjust the size slider until it reads cleanly at full export resolution.
