How does the social preview tester work?

Paste any public URL. We fetch the page's Open Graph and Twitter Card meta tags, then render preview cards that match how Twitter/X, Facebook, LinkedIn, and Discord will display your link when shared.

What does it validate?

Missing og:image, image dimensions too small for Facebook/LinkedIn, title length truncation, missing description, Twitter aspect-ratio crop risk, and missing twitter:card meta.

Can I fix issues directly?

Yes. Each card has a Fix in Editor button that opens our free editor pre-loaded with a 1200×630 canvas (the universal OG image preset), the safe-zone overlay, and your current image as the base layer.

Completely free. No signup, no watermark, no API key required. Pages are fetched from their public servers — same as Facebook's debugger or Twitter's card validator do.

Frequently asked

What does this tool actually check?

Six things: whether the page has an og:image at all, whether the image is large enough for Facebook and LinkedIn (≥600px on the short side), whether the title fits in their truncation limits, whether there’s an og:description, whether the og:image will hard-crop awkwardly on Twitter’s 1.91:1 large card, and whether a twitter:card meta tag is set.

How is this different from Facebook’s Sharing Debugger or Twitter’s Card Validator?

Those tools each cover one platform and require you to switch between them. They’re also developer-focused — raw meta-tag dumps and validation logs. Ours renders all four platforms side-by-side as visual cards, and the issues come with a one-click path to actually fixing the image.

What does “Fix in Editor” do?

Opens our free editor with the canvas pre-sized to 1200×630 (the universal OG image size — works for Facebook, Twitter large card, LinkedIn, and Discord), with a safe-zone overlay so you can see what each platform will and won’t crop. If the page already has an og:image, it loads as the base layer so you can edit rather than start from scratch.

Does this work for any URL?

Any public URL. Pages behind login walls, paywalls, or with aggressive bot detection may return limited data. We follow redirects, so short links (bit.ly, t.co, etc.) work fine.

Why don’t my changes show up in the preview after I update my site?

Facebook, Twitter, and LinkedIn each cache previews for hours to weeks. After updating your meta tags, you’ll usually want to re-scrape via Facebook’s Sharing Debugger, Twitter’s Card Validator, or LinkedIn’s Post Inspector to force a refresh of their cache. Our tool always fetches fresh — no caching delays here.
