How to preview Open Graph and Twitter Cards
- Fill in the fields. Enter your page title, description, URL, image, and other details.
- See live previews. The tool renders visual previews for both Open Graph (Facebook, LinkedIn) and Twitter Card.
- Generate tags. Click Generate to get the HTML meta tags for both Open Graph and Twitter Card.
- Copy or download. Use Copy to copy tags to clipboard or Download to save as HTML.
All generation happens locally in your browser. Your data never leaves your device.
Open Graph Image Guidelines
Recommended size: 1200×630 pixels (1.91:1 aspect ratio). Use this as a practical starting point for Open Graph images — no single size guarantees identical rendering across all services, since each platform crops and scales previews differently.
Test how images survive smaller or cropped previews, especially square crops on mobile devices, where content near the edges can be cut off.
When publishing, use absolute, public HTTPS URLs for both the page (og:url) and the image (og:image) so crawlers can fetch them.
Frequently Asked Questions
- No. All preview generation happens entirely in your browser. Your data never leaves your device.
- Open Graph (og:*) is used by Facebook, LinkedIn, Slack, and many other platforms. Twitter Card (twitter:*) is specific to Twitter/X. Both can coexist on the same page. The tool generates both so your links look great everywhere.
- Open Graph recommends 1200x630 pixels (1.91:1 ratio). Twitter Cards also recommend 1200x630 for summary_large_image. Minimum is typically 300x157.
- Once the page is loaded, the tool works offline because all logic runs client-side.
Open Graph Preview: Validate Social Share Cards Before You Publish
Open Graph Preview is a free developer tool in the Web category that simulates exactly how your web pages appear when shared on social platforms and messaging apps that consume Open Graph meta tags, including Facebook, LinkedIn, Discord, Slack, iMessage, and WhatsApp. It reads og:title, og:description, og:image, og:type, og:url, and og:site_name from your markup, then renders a realistic link card so you can identify truncated headlines, missing thumbnails, incorrect image aspect ratios, or broken canonical URLs before your audience ever sees them. Catching these problems early protects click-through rates, preserves brand credibility, and prevents the embarrassment of shipping a broken social preview to production. A single missing og:image can turn a carefully written article into a plain text link that gets ignored, while an oversized image may be cropped unpredictably on mobile feeds. Because link previews often determine whether a user clicks or scrolls past, validating Open Graph markup is an essential part of modern frontend quality assurance, especially for teams that publish content at scale.
Use Cases
Engineering teams use Open Graph Preview to quality-assure blog post launches, verify e-commerce product thumbnails before seasonal campaigns, audit documentation links pasted into Slack workspaces, and confirm dynamically generated meta tags render correctly on single-page applications where tags are injected client-side. Marketing teams preview campaign landing pages before ad budgets go live, while open-source maintainers check that project repository link cards look professional when shared in developer communities, Discord servers, and weekly newsletters. Content teams also use it to A/B test headline and image combinations, comparing which preview variant drives the strongest engagement before committing to a final design. Any team that publishes URLs publicly benefits from validating exactly how those links look in the wild.
How-To
- Paste the full URL of the page you want to preview into the input field.
- Click Preview to fetch the page and extract its Open Graph meta tags.
- Inspect the generated card: title length, description copy, image preview, dimensions, and site name.
- Edit og:title, og:description, or og:image directly and refresh to test variations instantly.
- Deploy the corrected meta tags, re-run the preview, and share your link with confidence.
Consistent Open Graph validation turns every social share into a polished, clickable asset. Add Open Graph Preview to your pre-deploy checklist for every new page, campaign, and major redesign so your brand always puts its best foot forward wherever links appear, and never publish a broken link card again.
