Uitly Link Preview Generator is a free online tool that fetches Open Graph metadata from any public URL and shows you how the link will appear when shared on Twitter, Facebook, LinkedIn, WhatsApp, and as a generic Open Graph card. No signup required, no usage limits, and the preview appears in real time.
Uitly's link preview generator shows you exactly how any URL appears when shared on Twitter, Facebook, LinkedIn, WhatsApp, and as an Open Graph card. Check for missing metadata, identify broken OG images, and fix social sharing issues before publishing. No signup. No cost.
A link that shows no image or a generic title on social media loses clicks before anyone reads the headline. This tool reads the live Open Graph tags from any public page and simulates what each platform's card renderer will display, so you can catch problems before they cost you engagement.
See how your URL appears on Twitter, Facebook, LinkedIn, WhatsApp, and as a generic Open Graph card, all from a single URL check. No switching between tools.
The tool reads every Open Graph tag on your page including og:title, og:description, og:image, og:site_name, and twitter:card, and displays them in a clear, structured overview.
Instant pass and fail indicators show which metadata tags are present and which are missing. Fix the gaps before your content goes live to avoid poor social sharing performance.
The tool fetches live metadata directly from the target page every time you run a check. You always see the current state of the page, not a cached version.
Every link preview check is completely free with no account needed and no usage limits applied. Run as many checks as your workflow requires.
Copy the full metadata as a JSON object with one click. Use the exported data in audits, reports, or developer handoffs without retyping any values.

We'll fetch the Open Graph metadata and show you previews for 5 platforms
Five steps from URL to a fully checked social media preview. No account required and no payment screen appears at any point.
Paste any public URL into the input field. The tool accepts links from any website, blog post, product page, or web application.
The tool fetches the Open Graph tags, Twitter Card tags, and other metadata directly from the target page in real time.
See all detected tags including title, description, OG image URL, site name, and Twitter card type. Pass and fail indicators show which tags are present and which are missing.
Switch between the Twitter, Facebook, LinkedIn, WhatsApp, and Open Graph tabs to see exactly how the link appears in each platform's card format.
Add any missing Open Graph or Twitter Card tags to your page's HTML head section, then run the preview tool again to confirm the fix worked before publishing.
A broken or missing link preview costs engagement on every platform. Here is exactly why checking matters and what each problem looks like.
A well-configured link preview with a compelling image and clear title consistently outperforms a blank or auto-generated preview. Checking before you share lets you confirm the card looks as intended.
Many pages are missing og:image or og:description entirely. Without these tags, social platforms either show no preview or pull random content from the page, which damages first impressions.
An og:image URL that returns a 404 error causes social platforms to show no image at all. The preview tool reveals broken image URLs so you can fix them before the content goes live.
Social platforms cache link previews for hours after the first share. This tool fetches live metadata directly from the page, so you see the current state and can confirm a fix before forcing a cache refresh.
Twitter Cards use different tags from Open Graph. LinkedIn reads og:image but has specific image size requirements. Checking each platform tab shows you exactly what each one will display.
The JSON export button copies all detected metadata to your clipboard. Paste it directly into audit spreadsheets, developer tickets, or client reports without retyping any values.
Checking Open Graph tags manually means opening browser developer tools, navigating to the Elements panel, and searching through the head section for meta tags. For non-developers and anyone checking pages quickly across a content workflow, that process is slow and error-prone.
This tool fetches and displays every Open Graph and Twitter Card tag in a structured overview with a pass and fail score, and then renders a realistic preview for five platforms without requiring any browser extension, developer account, or technical knowledge. Paste the URL, see the result, and fix what is missing.
Open Graph tags are a set of HTML meta tags placed inside the head section of a web page. Facebook created the Open Graph protocol in 2010 to give web publishers direct control over how their pages appear when shared on social networks. Twitter, LinkedIn, WhatsApp, Slack, Discord, and most other platforms adopted the same standard shortly after.
When someone shares a URL on social media, the platform sends an automated request to fetch the page and reads the Open Graph tags from the HTML. It uses those tags to build the link card, including the image, title, and description that appear in the feed. If the tags are missing, outdated, or pointing to a broken image URL, the platform either shows a blank card or guesses at the content using whatever text it finds on the page, which rarely produces a result worth clicking.
Every page that gets shared on social media should have at minimum an og:title, og:description, and og:image. Pages with all three set correctly and with a well-sized image consistently achieve higher click-through rates than pages with incomplete or missing Open Graph metadata.
These are the tags that the Uitly Link Preview Generator checks and scores. Here is what each one does and how to implement it correctly.
og:titleRequiredThe title of your page as it appears in social media cards. Keep it under 60 characters so it does not get truncated. Write it like a headline, not a page title.
<meta property="og:title" content="Free Link Preview Generator — Check OG Tags Online" />og:descriptionRequiredA short summary of the page shown below the title in most social media cards. Aim for 150 to 160 characters. Make it compelling because it directly influences whether someone clicks the link.
<meta property="og:description" content="See how any URL looks on Twitter, Facebook, LinkedIn and WhatsApp before sharing." />og:imageRequiredThe image that appears in social media cards. Use an absolute URL, not a relative path. The recommended size is 1200 by 630 pixels. This is the most impactful tag because an image dramatically increases engagement compared to a text-only card.
<meta property="og:image" content="https://uitly.pro/img/link-preview-og.webp" />og:urlRecommendedThe canonical URL of the page. This helps social platforms identify the definitive version of the page and prevents duplicate content issues when the same page is accessible at multiple URLs.
<meta property="og:url" content="https://uitly.pro/link-preview-generator" />og:typeRecommendedThe type of content on the page. Use website for standard pages and article for blog posts and news articles. The default is website, so this tag is optional unless you need a specific type.
<meta property="og:type" content="website" />og:site_nameRecommendedThe name of your website or brand. This appears separately from the title in some platforms and helps establish brand recognition in social media cards.
<meta property="og:site_name" content="Uitly" />twitter:cardRecommendedControls how Twitter displays the link card. Use summary_large_image to show a large image above the title and description. Without this tag, Twitter falls back to a small square thumbnail card even if a large og:image is present.
<meta name="twitter:card" content="summary_large_image" />Each platform handles og:image differently. Use these specifications to ensure your image displays correctly on every platform without cropping or compression.

WhatsApp shows a small thumbnail from og:image alongside the title and description. Very large images above 300 KB may not load on slower connections. Square images also work well.
Use 1200 by 630 pixels as your standard OG image size. It satisfies the requirements for Twitter, Facebook, and LinkedIn simultaneously with a single image file.
Most link preview problems come from a small set of recurring mistakes. Here are the most common ones and the specific fix for each.
Replace /img/photo.jpg with https://uitly.pro/img/photo.jpg. Social media crawlers fetch the og:image from an external server and cannot resolve relative paths.
Use a minimum size of 600 by 315 pixels. Platforms like Facebook display small images as tiny inline thumbnails instead of full-width cards, which dramatically reduces visual impact.
Add a twitter:card tag set to summary_large_image. Without it, Twitter ignores your og:image and shows a plain text card or a tiny square thumbnail even when a large image is present.
Write og:title as a human-readable headline that makes someone want to click the link. It does not affect search rankings. It only affects social media card engagement.
Use the platform-specific debugger tools: Facebook Sharing Debugger, LinkedIn Post Inspector, and Twitter Card Validator to force a cache refresh after making OG tag changes.
Link preview checking fits into many different workflows. Here is who gets the most value from it.
Verify that every piece of content produces the correct social card before publishing. Catch missing images and broken descriptions in a seconds-long check rather than discovering the problem after the content goes live.
Confirm that OG tag implementations work correctly without switching to browser developer tools. Check multiple pages quickly during a content migration or CMS upgrade.
Audit Open Graph metadata across a site as part of a technical SEO review. The JSON export makes it easy to document current metadata and compare it against target values in a spreadsheet.
Preview every link before it goes into a scheduled post queue. Eliminate the experience of a campaign going live with a broken or missing card image that kills click-through rates.
Ensure product pages, landing pages, and blog posts produce compelling social cards without relying on a developer to check every time. The tool is self-serve and requires no technical knowledge.
Uitly offers 23 free browser-based tools for marketers, developers, and designers. Here are the tools most useful alongside link preview checking.
Common questions about Open Graph tags, link previews, image sizes, and how the tool works.
A link preview generator fetches the Open Graph metadata from a web page and shows you how that page will appear when someone shares the URL on social media platforms like Twitter, Facebook, LinkedIn, and WhatsApp. It reads tags like og:title, og:description, og:image, and twitter:card to simulate what each platform's card will look like.
Open Graph tags are HTML meta tags placed in the head section of a web page. They control how the page appears when shared on social media. Without them, platforms either show no preview at all or guess at the title and description using page content, which often produces poor results that reduce click-through rates.
Social platforms cache link previews for hours or sometimes days after the first share. If you recently updated your Open Graph image, the platform may still show the old cached version. You can use the platform's own scraper tools to force a cache refresh. The Uitly Link Preview Generator always fetches the current live metadata, so it shows you what is actually in the page right now.
The recommended Open Graph image size is 1200 by 630 pixels with an aspect ratio of 1.91 to 1. This size works well across Twitter, Facebook, and LinkedIn. Images smaller than 600 by 315 pixels may not display as large cards on some platforms. Always use a JPG or PNG file and keep the file size under 5 MB for reliable display.
No. The tool can only fetch metadata from publicly accessible URLs. Password-protected pages, pages behind login walls, and private staging environments cannot be fetched. This is the same limitation that social media platforms themselves have when generating link previews.
