Preview how a URL appears as a Twitter / Facebook / LinkedIn share card. Free, private, runs in your browser.
This tool needs a server because the browser can’t fetch arbitrary cross-origin URLs. Our Cloudflare Worker fetches the public URL you typed and returns the parsed result — nothing is stored.
Paste any public URL — we’ll fetch its OpenGraph + Twitter Card meta tags and show how each platform renders it.
How this works: a tiny Cloudflare Worker at workers.convertful.app fetches the public URL you typed and parses the <head> — nothing is stored. Pairs well with robots-tester and ssl-checker.
OpenGraph Preview fetches a public URL on your behalf, parses its <head>, and renders the same social-share card that Twitter, Facebook, LinkedIn, Slack, Discord, and most other unfurl-aware platforms would build for it. You see the title, description, image, site name, favicon, and Twitter Card variant — plus the raw og:* and twitter:* tags so you can audit which value will end up where. It's the fastest way to verify a fix before re-sharing the URL on a real channel.
When someone pastes your URL into a chat, message, or post, the platform fetches the head once and caches the unfurled card for hours or days. If your og:image is broken or your og:title is missing, every subsequent share looks ugly until the cache expires. Marketers and growth teams spend significant time on these tags because they directly affect the click-through rate of every link they ship. A 2-line fix to your <head> can lift CTR several points.
Five usual culprits: (1) og:image is a relative path — must be absolute. (2) og:image is hosted on a CDN that returns slow or missing CORS headers — use a domain you control. (3) The HTML is rendered client-side via JavaScript — Open Graph parsers don't run JS, so the <meta> tags must be in the initial server response. (4) The page returns a 4xx / 5xx for unauthenticated requests. (5) The CDN gates HTML behind a JS challenge or paywall. Our tool surfaces the HTTP status and final URL so you can pinpoint which one applies.
Compare the rendered card to what you want shared. Check the resolved og:image URL by clicking it — if it 404s in your browser, it'll 404 for Twitter too. Compare the title and description against your target keywords. If you're testing a Twitter-specific layout, check that twitter:card is set to summary_large_image (not just summary, which produces a smaller card). The raw tag table is grouped so you can scan and find the line that needs editing in your CMS or template.
This is one of a few Convertful tools that uses a server, because the browser can't fetch arbitrary 3rd-party pages due to CORS. The server is a Cloudflare Worker at workers.convertful.app — open-source-style code in our repo at workers/api/. Each request: the Worker fetches the public URL you typed, parses the head, returns JSON. Nothing is stored — no logging, no analytics on your queries, no caching beyond Cloudflare's standard 5-minute edge cache for the response itself. Your URL is the only thing we see, and only for the moment of the request.
The Open Graph image, title, description, site name, and Twitter Card metadata that Twitter, Facebook, LinkedIn, Slack, Discord, and most other platforms use to render a link unfurl. We also surface the resolved favicon and canonical URL so you can see what would appear in shares.
Yes. We follow up to the platform's default of redirects and report the final URL. Useful when you're checking a short-link or a tracked URL.
It hits the same head-tag parsing path that Facebook and Twitter use, but doesn't queue a real share or warm anyone's cache. You can iterate on og:image / og:title and see the result in seconds without spamming a test channel.
To work, this tool asks our Cloudflare Worker at workers.convertful.app to fetch the public page you specify, parses the head, and returns it. Your URL is the only thing we see, and only for the moment of the request. Nothing is stored, logged, or shared.
The most common reasons: a relative og:image URL (must be absolute), missing dimensions on the image, a slow server (timeouts at 10 s), or a CDN that gates HTML behind a JavaScript challenge — Open Graph parsing happens before JavaScript runs.
