See how a link looks when shared on social — from its Open Graph and Twitter card tags.
When you paste a link into Facebook, X/Twitter, LinkedIn, Slack, WhatsApp, or iMessage, the app does not just show the raw URL. It scrapes the page for Open Graph and Twitter card meta tags and builds a rich preview: an image, a title, a description, and the site name. If those tags are missing, wrong, or point at a stale image, your link shows up blank or off-brand, and that preview is often the only thing deciding whether anyone clicks. This tool fetches a page and shows you the preview those tags produce, before you publish.
Enter a URL and the previewer reads the page, pulls its og: and twitter: tags, and renders an approximation of the share card alongside a table of every tag it found. You can confirm the title and description read well, that the image exists and is the right one, and that the site name is set. It is the fast way to debug why a link looks wrong when shared, to check a page after editing its meta tags, or to compare how a competitor sets up their previews. Different platforms render cards slightly differently, but they all read the same underlying tags shown here.
Reading another site’s HTML from your browser is blocked for security reasons, so the page is fetched on Reslug servers on your behalf. The URL is used only to build the preview and is not stored.
Enter the link you plan to share in the Page URL field. Use the canonical page URL, the same one people will paste.
Click Preview. The tool fetches the page and reads its Open Graph and Twitter card meta tags.
The Card preview shows the image, title, description, and site name roughly as a social platform would render them.
The Tags found table lists every meta property and its content, so you can spot anything missing or incorrect and fix it on the page.
Open Graph (og:) tags are meta tags in a page’s HTML head that tell social platforms how to present the page when it is shared. The key ones are og:title, og:description, og:image, and og:url. Twitter adds its own twitter: tags for cards, though it falls back to Open Graph when they are absent.
Usually because og:image is missing, points to a URL that no longer exists, uses a relative path the platform cannot resolve, or the image is too small. This tool shows whether an image tag was found and what it points to so you can correct it.
Social platforms cache the preview they scraped earlier. After you fix your tags, use the platform’s own debugger (such as Facebook’s Sharing Debugger or LinkedIn’s Post Inspector) to force a re-scrape. This tool always fetches the page live, so it reflects your current tags immediately.
Close, but not pixel-for-pixel. Facebook, LinkedIn, X, Slack, and others crop images and lay out the title and description slightly differently. They read the same Open Graph and Twitter tags, so getting those right here gets the card right everywhere; the layout shown is a representative approximation.
The URL is sent to Reslug servers to fetch the page, since a browser cannot read another site’s HTML directly. It is used only to build the preview and is not stored.
Reslug short links carry your own preview image, title, and description, so your brand shows up wherever people paste them.
